688943e779 Fix audio input rate issue on Windows Vista
Windows Vista has a broken rate converter which gets invoked when an
input audio stream at 48kHz sampel rate is requested. I've no idea why
our application can't get exclusive access to the audio input device
and have a unconverted stream direct at 48kHz.

To get around this our down sampling filter for audio input from 48kHz
to 12kHz is disaabled by default on Windows Vista, instead we request
a 12kHz stream and process it directly.

This default behviour can be overriden by specifying the following
settings value:

[Tune]
Audio\DisableInputResampling=false

This settings value defaults to true on Windows Vista and false
everywhere else so normally needn't be present.

b6559fae7c Added audio channel support.
Audio input can be mono, left of stereo pair or, right of stereo
pair. Audio output can be mono, left of stereo pair, right of stereo
pair or, both of stereo pair (the same output goes to both channels in
both mode). Settings are remembered between sessions.

Stream channel suport is implemented mainly in the new AudioDevice
class which is now the base class of Modulator and Detector.

Audio channels are selected on the configuration screen. Only
supported channel configurations per device can be selected.

Audio output volume (actually attenuation) is now possible from the
GUI. I have added a slider control to the main window; I don't
necessarily propose this as a final release location for the widget as
I understand that changes to the main screen are sensitive. This
location is just a starting suggestion for a trial. The volume
(attenuation) setting is remembered between sessions and is not device
dependent. This addresses all issues of volume setting on *nix
versions since there is no need to use pavucontrol to set audio
levels. The volume (attenuation) action is logarithmic.

Shaped CW keying has been implemented in Modulator although it is
currently disabled as I am not 100% happy wth the implementation. If
you want to try it define the C++ preprocessor macro WSJT_SOFT_KEYING
in your build.

The Modulator instance has been moved to the same thread as the
SoundOutput instance as it should have been since the output callback
already operates in that thread. Cross thread slots are now correctly
called in a thread safe way as a result.

A number of files where in the SVN repository with DOS line endings
which I have removed. SVN users on Windows need set the config for
native line endings so that DOS line endings are automatically
stripped on checkin.

The DevSetup class now holds it's UI o the heap to reduce imapact on
build dependencies.

The application settings are now passed to objects from the main.cpp
file. Management of settings are moved to the responsible classes (top
level windows). This has involved a few settings moving groups so
users will see some settings reverting to default values on the first
run of an update.

Persistance of top level windows geometry and position is now handled
in the recommened manner (constructor for load, closeEvent for store
in modal windows and, hideEvent for store in modeless dialogs).

The MainWindow class now holds its children as members rather than
global variables.

The LogQSO class now hides its implementation and takes responsibility
for its own settings and widows rendering parameters. A new settings
file group is implemented to persist the LogQSO class settings.

The WideGraph class now hides its implementation and manages its own
settings and window rendering parameters.

e602def8b1 Qt 5 Audio replaces PortAudio.
Currently only Qt5 or above is known to work with this code. It may be
possible to backport it to Qt4 if required.

Audio output goes back to a separate thread to try and minimize
stutters in streaming on Windows particularly.

A crash on Linux due to mishandling of stereo audio output has been
fixed and both left and right channels are now correctly synthesised
with identical contents.

Rigs are enumerated directly from hamlib API rather than running a sub
process reading output of rigctl -l. This was initially done to get
rid of some GUI thread blocking in the configuration dialog, but is
generally a better way of doing it anyway.

Some refactoring in MainWindow to accomodate the audio streaming,
modulation and detecting classes.

Exit handling for application refactored to use signals rather than
brute force event loop exit. This was required to get correct thread
shutdown semantics.

The GUI update timer is now stopped during application shutdown which
is necessary to stop crashes when shutting down gracefully with
signals and window close() calls.

There is an outstanding issue with Linux audio streams; the QAudio
Input/Output classes create a new stream name each time a stream is
started. This doesn't play well with PulseAudio utilities such as
pavucontrol to set stream volume as settings are lost every tx
period. I have tried to keep a single stream for all output but there
are problems restarting it that haven't been resolved yet.

The QtCreator project file has been rearranged a little because it
passes all the object files to the linker rather than using an archive
library. Since the GNU linker is single pass; the object files need to
be in a logical order with definitions appearing afer references to
them. This was required to avoid a linking error.

The lib/Makefile.linux has been enhanced to use the fortran compiler
to locate the correct version of the Fortran library to use. This is
necessary on the latest Linux distros because the unversioned symlink
to compiler support libraries is no longer provided. This only an
issue with mixed programming language links where the linker driver
for one language has to link support libraraies for another language.

87ad45188f Most of these changes are thanks to G4WJS. Audio I/O is now done using
Qt's built-in QAudio calls rather than PortAudio.  Also includes some
refactoring of the arrangement for these calls, and more use of C++ style.

c4e6f89b0b This code now compiles OK in either Qt4 or Qt5. To run in Qt5 we'll need
a Qt5-compatible "thermo" widget.

67a99ccbc4 Working toward compiling WSJT-X under Qt5. It doesn't work, yet.
The present code is still OK in Qt 4.x.  For Qt5, must replace 
#include <QtGui> by #include <QtWidgets> in several places, and 
uncomment these lines

//#include <QtConcurrent/QtConcurrentMap>
//#include <QtConcurrent/QtConcurrentRun>

in mainwindow.cpp.  More work still to do, for Qt5!

04dcf0a528 Major changes to the MAP65 branch. This branch is now a copy of
MAP65 v2.3.0, r631, as checked out from the SVN repository on
pulsar.princeton.edu.  If all goes well with this commit, subsequent
MAP65 development will use the Berlios repository.
