0f72c3fd9b Abandon getting changeset revision number from svn keyword expansion
Subversion keyword expansion of $Rev:$ in  a file is hopeless as it is
impossible to  coordinate with  a release. Revert  to an  empty string
when it can't be discovered with svn info etc..

Further changes to the way verion and revision numbers are generated

Local builds from  source tar balls or the  two phase wsjtx-superbuild
no longer specify  any revision, just the version  number. Since these
sort  of builds  are  expected  to be  release  candidates or  release
versions the revision (svn changeset  number) is implicit from the svn
tag of the version.

Merged from wsjtx-1.4 branch.

c70f523952 Optimized kvasd download in build
The kvasd binary  need only be downloaded  if the MD5 hash  for it has
changed.

Also fixed a defect in the status check of the MD5 hash download.

messages.

46064e3af3 Add on-line KVASD install to Windows NSIS installer
To comply  with the  WSJT_X GPL  v3 license,  the closed  source KVASD
executable  must  be  delivered   separately  and  optionally  to  end
users. To facilitate  this a new install option has  been added to the
Windows  installer  to install  KVASD  by  downloading it  at  install
time. The installer  first downloads the KVASD EULA  from the Internet
and presents it  to the user for reading and  agreement.  If agreement
is  given  the  KVASD  binary  is downloaded  from  the  Internet  and
checksummed using an  MD5 hash, if that passes, it  is installed along
with WSJT-X.  An  uninstall record is also written to  ensure that, if
installed, KVASD will be un-installed if WSJT-X is un-installed.

To facilitate this enhancment to the NSIS installer the standard CPack
NSIS  installer script  template has  been overridden  with a  project
specific version.   This version also  implements the more  modern and
recomended nsDialogs mechanism for  installer custom page construction
including the install options page. See CMake/Modules/NSIS.template.in
for  details   and  CMakeCPackOptions.cmake.in   for  usage   in  this
installer.

ef35c0bd48 Use correct svn revision in program name text
The latest revision rather than the revision of the last change to the

ffa6305b98 Better version identification.
An  ambiguity  existed  between  release  candidates  and  development
versions  as there  was no  definitive identification  for development
versions.

Added a  new version number  suffix of  '-devel' which appears  if the
release candidate number is missing  or zero in Versions.cmake and the
revision is not marked as a release version, also in Versions.cmake.

Also re-factored setting of version number suffiexes to a single place
in in CMake/VersionCompute.cmake.

d4e55a093d Add local HTML help file to help menu.
So that a manual can be viewed without an Internet connection a second
manual action has been added to  the WSJT_X help menu. This shells out
to the default web browser with a local file target.

The build has been enhanced to install and package the current version
of the  HTML user manual  as downloaded from  the project web  site at
build time

The package  file locations have  been adjusted to be  compatible with
the QStandardPaths  class so that  its locate()  method can be  used to
portably access resources like this local help file

5b05f229a1 Try to form a consistent program title and revision specification from
all types of build.

CMake builds use 'svn info' (the git-svn equivalent is also supported)
to  get the  real latest  revision of  the workspace  that is  used to
source a  build. If the sources  are not in VCS  workspace (build from
source  snapshot  archive for  example)  then  the  $Rev$ svn  keyword
expansion in mainwindow.cpp is used despite its issues with accuracy.

Non-CMake builds use the $Rev$ keyword expansion where possible.

If a CMake  build is from a VCS workspace  with local modifications; a
'-dirty' suffix is added to the revision number to denote that.

If no revision number information can be found the word 'local' is
used as a revision number.

The revision  specification is used in  the WSJT-X "about"  box and is
sent  to PSKReporter.info  as part  of the  local  station information
(this     can     be     viewed     at     the     statistics     page
http://pskreporter.info/cgi-bin/pskstats.pl).

5709ae53df Fixed and improved SVN revision lookup in the CMake script.
The lookup was broken and always returning 'local'.

It now returns 'local' for a non svn source tree,
'r<revno>-dirty' for a source tree with uncommitted changes,
'r<revno>' for a clean svn source tree.

Unversioned files are ignored for now.

Also added some diagnstics output in CMake script to aid debugging Qt
plugin location issues.

9247e10115 Added support for use of "Standard" locations for writable files.
This allows  writable files  to be  located in  the "correct"
         location for  each platform rather  than in the  directory of
         the  executable  which, in  general,  is  not recommended  or
         allowed in some cases.

         A preprocessor macro  WSJT_STANDARD_FILE_LOCATIONS is used to
         switch be tween old and new functionality, currently it is on
         by default.  It  can be turned off by defining  it to a false
         value (0)  or more simply  with cmake-gui setting  the option
         with  the same  name.  JTAlert  can  only work  with the  old
         non-standard file  locations until  Laurie VK3AMA  chooses to
         support the new file locations.

         Even  if the  above is  not  enabled; the  QSettings file  is
         written to a  user specific location so it will  be shared by
         all instances  of the  program (i.e.  across  upgrades).  See
         below for multiple concurrent instance support changes.

Added a command line parser module for Fortran.

         Added 'lib/options.f90'  to facilitate more  complex argument
         passing to jt9 to cover explicit file locations.

Changed the way multiple concurrent instances are handled.

         This is  to allow the program  to be run multiple  times from
         the same installation directory.

         A new wsjtx command line  optional argument is available "-r"
         or  "--rig"   which  enables  multiple   concurrent  instance
         support.  The  parameter of the  new option is a  unique name
         signifying  a rig  or equivalent.   The name  is used  as the
         shared memory segment key and  in window titles.  The name is
         also used to  access unique settings files  and writable data
         files like ALL.TXT  and log files.  No attempt  has been made
         to share these files between concurrent instances.

         If  "-r" or  "--rig" is  used  without a  parameter it  still
         enables  multiple   concurrent  instance  support   for  that
         instance.  All instances must use  a unique parameter, one of
         which may be empty.

         The        rig       name        is       appended        the
         QCoreApplication::applicationName() for convenient usage like
         window titles.

Set non Qt locale to "C".

         This ensures that C library functions give consistent results
         whatever the  system locale is set  to.  QApplication follows
         the system locale as before.  Thus using QApplication and its
         descendants  like widgets  and QString  for all  user visible
         formating will give correct l10n and using C/C++ library will
         give consistent formatting across locales.

Added top level C++ exception handling to main.cpp.

         Because  the   new  transceiver  framework   uses  exceptions
         internally, the main function now handles any exceptions that
         aren't caught.

Retired devsetup, replaced with Configuration.

         Configuration  is  a  class  that encapsulates  most  of  the
         configuration  behavior.   Because  rig configuration  is  so
         closely coupled with rig operation, Configuration serves as a
         proxy  for   access  to  the  rig   control  functions.   See
         Configuration.hpp  for  more  details  of  the  Configuration
         interface.

Menu changes.

         Various checkable  menu actions moved  from main menu  to the
         Configuration  dialog.   The  whole settings  menu  has  been
         retired with  the single  "Settings..."  action moved  to the
         file  menu  for  consistency  on  Mac  where  it  appears  as
         "Preferences" in line with Mac guidelines.

New data models for data used by the application.

         ADIF amateur band parameters,  free text message macros, spot
         working   frequencies  and,   station  information   (station
         descriptions and transverter offsets per band) each implement
         the  QAbstractItemModel interface  allowing them  to be  used
         directly with  Qt view widgets  (Bands.hpp, FrequencyList.hpp
         and, StationList.hpp).  Configuration  manages maintenance of
         an instance of  all but the former of the  above models.  The
         ADIF band  model is  owned by  Configuration but  requires no
         user maintenance as it is immutable.

Band combo box gets more functionality.

         This  widget is  now an  editable QComboBox  with some  extra
         input capabilities.

         The popup list is still the list of spot working frequencies,
         now  showing the  actual  frequency decorated  with the  band
         name.  This  allows multiple  spot frequencies  on a  band if
         required.

         The  line edit  allows direct  frequency entry  in mega-Hertz
         with  a completer  built  in to  suggest  the available  spot
         working frequencies.   It also  allows band name  entry where
         the  first  available  spot working  frequency  is  selected.
         Recognized band names are those  that are defined by the ADIF
         specification and  can be found  in in the  implementation of
         the ADIF bands model (Bands.cpp).

         If an out of band frequency  is chosen, the line edit shows a
         warning red  background and the  text "OOB".  Out of  band is
         only defined  by the  ADIF band limits  which in  general are
         wider than any entities regulations.

Qt 5.2 now supports default audio i/p and o/p devices.

         These devices are placeholders  for whatever the user defines
         as the  default device.   Because of  this they  need special
         treatment as  the actual device  used is chosen at  open time
         behind the scenes.

Close-down behavior is simplified.

         The close-down  semantics were broken such  that some objects
         were not being shut down cleanly, this required amendments to
         facilitate correct close down of threads.

User font selection added to Configuration UI.

         Buttons to set the application font and the font for the band
         and  Rx frequency  activity widgets  have been  added to  the
         Configuration UI to replace the file based font size control.

Free text macros now selected directly.

         The free text line edit  widgets are now editable combo boxes
         that have  the current free  text macro definitions  as their
         popup  list.   The old  context  menu  to  do this  has  been
         retired.

Astronomical data window dynamically formatted and has font a chooser.

         This window is now autonomous,  has its own font chooser and,
         dynamically resizes to cover the contents.

Double click to Tx enabled now has its own widget in the status bar.

QDir used for portable path and file name handling throughout.

The  "Monitor", "Decode",  "Enable  Tx" and,  "Tune"  buttons are  now
checkable.

         Being checkable allows these  buttons control their own state
         and rendering.

Calls to PSK Reporter interface simplified.

         In   mainwindow.cpp  the   calls   to   this  interface   are
         rationalized to just 3 locations.

Manipulation of ALL.TXT simplified.

         Moved, where possible, to common functions.

Elevated frequency types to be Qt types.

         Frequency  and FrequencyDelta  defined as  Qt types  in their
         meta-type system  (Radio.hpp).  They  are integral  types for
         maximum accuracy.

Re-factored rig control calls in mainwindow.cpp.

         The new  Configuration proxy  access to rig  control required
         many changes  (mostly simplifications) to the  MainWindow rig
         control code.  Some  common code has been  gathered in member
         functions   like   qsy(),   monitor(),   band_changed()   and
         auto_tx_mode().

Rig control enhancements.

         The  rig control  for  clients interface  is  declared as  an
         abstract    interface   (See    Transceiver.hpp).    Concrete
         implementations of this interface are provided for the Hamlib
         rig  control library,  DX Lab  Suite Commander  via a  TCP/IP
         command channel, Ham  Radio Deluxe also via  a TCP/IP command
         channel and, OmniRig via its Windows COM server interface.

         Concrete Transceiver implementations are expected to be moved
         to a separate thread after construction since many operations
         are blocking  and not suitable  for running in a  GUI thread.
         To facilitate this all  instantiation of concrete Transceiver
         instances are handled by  Configuration using a factory class
         (TransceiverFactory)   for   configuration  parameter   based
         instantiation.

         Various   common  functionality   shared  by   different  rig
         interface implementations  are factored out into  helper base
         classes that  implement or delegate parts  of the Transceiver
         interface.  They  are TransceiverBase  which caches  state to
         minimize expensive rig commands, it also maps the Transceiver
         interface  into a  more  convenient  form for  implementation
         (template methods).  PollingTransceiver that provides a state
         polling   mechanism  that   only   reports  actual   changes.
         EmulateSplitTransceiver  that  provides  split  operation  by
         QSYing on PTT state changes.

         EmulateSplitTransceiver can  be used with  any implementation
         as  it follows  the GoF  Decorator pattern  and can  wrap any
         Transceiver implementation.

         OmniRigTransceiver is  derived directly  from TransceiverBase
         since  it doesn't  require  polling due  to its  asynchronous
         nature.  OmniRigTransceiver is only built on Windows as it is
         a COM server client.  To build  it you must first install the
         OmniRig     client     on     the     development     machine
         (http://www.dxatlas.com/omnirig/).

         DXLabSuiteCommanderTransceiver          derives          from
         PollingTransceiver since  it is a  synchronous communications
         channel.   No  third  party  library  is  required  for  this
         interface.

         HRDTransceiver also derives from PollingTransceiver.  The HRD
         interface  library has  been  reverse  engineered to  provide
         functionality with  all available versions of  HRD.  No third
         party libraries are required.

         HamlibTransceiver  likewise  derives from  PollingTransceiver
         since  the Hamlib  asynchronous interface  is non-functional.
         Although this  class will interface with  the release version
         of Hamlib (1.2.15.3);  for correct operation on  most rigs it
         needs to  run with the  latest master branch code  of Hamlib.
         During development many changes to Hamlib have been submitted
         and accepted,  hence this requirement.  Hamlib  source can be
         obtained from git://git.code.sf.net/p/hamlib/code  and at the
         time of writing he master branch was at SHA 6e4432.

         The Hamlib interface directly calls the "C" interface and the
         modified rigclass.{h,cpp} files have been retired.

         There is a rig type selection of "None" which may be used for
         non-CAT  rigs, this  is actually  a connection  to the  dummy
         Hamlib device.

         PollingTransvceiver   derives    from   TransceiverBase   and
         TransceiverBase derives from the Transceiver interface.

         Each interface implementation offers  some possibility of PTT
         control via  a different serial  port than the CAT  port.  We
         also support PTT  control directly via a  second serial port.
         This is done  by delegating to a dummy  Hamlib instance which
         is   only   used   for   PTT  control.    This   means   that
         DXLabSuiteCommanderTransceiver,       HRDTransceiver      and
         OmniRigTransceiver  always  wrap  a  dummy  HamlibTransceiver
         instance.  The  factory class TransceiverFactory  manages all
         these constructional complexities.

         Serial port  selection combo  boxes are  now editable  with a
         manually  entered value  being  saved to  the settings  file.
         This allows  a non-standard  port device  to be  used without
         having to edit the settings file manually.

         For TCP/IP  network CAT  interfaces; the network  address and
         port  may  be specified  allowing  the  target device  to  be
         located on a different machine  from the one running wsjtx if
         required.  The  default used when  the address field  is left
         blank is the correct one for normal usage on the local host.

         Selecting a polling  interval of zero is  no longer possible,
         this  is because  the rig  control capability  can no  longer
         support one way connection.  This  is in line with most other
         CAT control software.

         In the Configuration dialog there are options to select split
         mode  control  by  the  software  and  mode  control  by  the
         software.  For  the former  "None", "Rig"  and "Fake  it" are
         available,  for  the latter  "None",  "USB"  and, "Data"  are
         available.  Because  tone generation is implicitly  linked to
         split mode  operation; it is  no longer possible to  have the
         software in split  mode and the rig not or  vice versa.  This
         may mean some rigs cannot be used in split mode and therefore
         not in dual JT65+JT9 until  issues with CAT control with that
         rig are  resolved.  Single  mode with VOX  keying and  no CAT
         control are still possible so even the most basic transceiver
         setup is supported as before.

         Configuration now  supports a  frequency offset  suitable for
         transverter   operation.     The   station    details   model
         (StationList.hpp) includes  a column  to store an  offset for
         each band if required.

CMake build script improvements.

         The CMakeLists.txt from the  'lib' directory has been retired
         with its  contents merged into the  top level CMakeLists.txt.
         Install  target support  has been  greatly improved  with the
         Release build  configuration now building a  fully standalone
         installation  on Mac  and Windows.   The Debug  configuration
         still   builds   an   installation   that   has   environment
         dependencies for  external libraries, which is  desirable for
         testing and debugging.

         Package target  support is largely complete  for Mac, Windows
         and, Linux, it should be possible to build release installers
         directly from CMake/CPack.

         Cmake FindXXXX.cmake  modules have been added  to improve the
         location of fftw-3 and Hamlib packages.

         Version numbers are now stored in Versions.cmake and work in
         concert with automatic svn revision lookup during build.  The
         version string becomes 'rlocal'± if there are any uncommitted
         changes in the build source tree.

Moved resource like files to Qt resources.

      	 Because location of resource files  (when they cannot go into
      	 the  installation directory  because of  packaging rules)  is
      	 hard to standardize.  I have used the Qt  resource system for
      	 all ancillary data files. Some  like kvasd.dat are dumped out
      	 to the temp (working directory)  because they are accessed by
      	 an external program, others like the audio samples are copied
      	 out so  they appear in  the data directory under  the default
      	 save directory.
