73df0d00ef 1. Alt+F8 arms "Call 1st" as if a CQ had been sent.
2. "Call 1st" label turns red when armed to respond to a caller.
3. Suppress some recognizable false decodes, send them to cumulative file
   "data_dir/false_decodes.txt".
4. Reduce sleep delay in decoder() to 10 ms.

d431e2cecd Restructuring in preparation for direct decoder invocation from wsjtx
Re-factor the JT4, JT65 and JT9 decoders as Fortran modules using type
bound  procedures, the  decoder types  implement a  callback procedure
such that he client of the decoder can interpret the decode results as
they need.

The JT4 decoder has a  second callback that delivers message averaging
status.  Also the  previously separate  source files  lib/jt4a.f90 and
lib/avg4.f90 have been merged  into lib/jt4_decode.f90 as private type
bound procedures of the new jt4_decoder type.

Re-factored the lib/decoder.f90 subroutine  to utilize the new decoder
types. Added local procedures to process decodes and averaging results
including the necessary OpenMP synchronization directives for parallel
JT9+JT65 decoding.

Added the  jt65_test module  which is  a basic  test harness  for JT65
decoding. Re-factored  the jt65 utility  to utilize the  new jt65_test
module.

Changed a  few integers  to logical variables  where their  meaning is
clearly binary.

f416a52def Make Fortran profiling timer function a callback with a default null implementation
Groundwork for calling the decoders directly from C/C++ threads.

To  access   the  timer   module  timer_module   must  now   be  used.
Instrumented code need  only use the module function  'timer' which is
now a  procedure pointer that  is guaranteed to be  associated (unless
null()  is assigned  to it,  which should  not be  done). The  default
behaviour of 'timer' is to do nothing.

If a  Fortran program  wishes to  profile code it  should now  use the
timer_impl module  which contains a default  timer implementation. The
main program should call 'init_timer([filename])' before using 'timer'
or     calling     routines     that     are     instrumented.      If
'init_timer([filename])'.  If it is called  then an optional file name
may  be  provided  with  'timer.out'  being used  as  a  default.  The
procedure 'fini_timer()' may be called to close the file.

The default  timer implementation is  thread safe if used  with OpenMP
multi-threaded code  so long as  the OpenMP  thread team is  given the
copyin(/timer_private/) attribute  for correct operation.   The common
block /timer_private/ should  be included for OpenMP  use by including
the file 'timer_common.inc'.

The module 'lib/timer_C_wrapper.f90' provides  a Fortran wrapper along
with 'init' and 'fini' subroutines  which allow a C/C++ application to
call timer instrumented  Fortran code and for it  to receive callbacks
of 'timer()' subroutine invocations.  No C/C++ timer implementation is
provided at this stage.

d5bc774641 Get rid of jt9com and npar common blocks
Also  use correct  C binding  and have  compilers determine  sizes and
offsets.

The wsjtx.exe program now owns the  decoder shared data that is shared
with symspec.  It is now in  struct dec_data, still a  global variable
for now but hopefully a MainWindow member variable soon.

The struct  dec_data (in both C/C++  and Fortran) has a  sub structure
with the decoder  parameters which enables copying  and manipulating a
lot cleaner.

New  of  changed types  of  shared  data  must  still be  modified  in
commons.h and a  new file lib/jt9com.f90, they must stay  in sync as a
pointer to the structure is passed between C and Fortran.

94472ac31c Many changes in program jt9[.exe] aimed at speeding up the decoders.
The long FFTs can now use the multi-threaded FFTW routines.
Subroutine decode9.f90 was renamed jt9fano.f90.
The JT9 decoder's top-level functions were removed from decoder.f90
and put into a separate subroutine decjt90.f90.
Subroutine decoder.f90 is now configured for possible use of OpenMP 
SECTIONS, with the JT9 and JT65 decoders running concurrently on
a multi-core machine.  Note, however, that this concurrent processing 
is not yet fully implemented.  Probably calls to timer need to be removed; 
some variables used in calls to jt65a and decjt9 may need to be 
declared PRIVATE in decoder; some sections probably need to be declared 
CRITICAL; probably some SAVE statements in downstream routines have
made them not thread-safe; etc., etc.  

I'm a neophyte at using OpenMP.  Comments, suggestions, and/or tests by
others will be welcome!

f37ed4cd78 Take advantage of the new KVASD v1.12
Pass the  temporary directory to  jt9 and use  it to give  the correct
paths  to  temporary files.  Also  jt9  passes  the absolute  path  to
kvasd.dat in the temporary directory to kvasd.

Clear out all the annoying cruft that has accumulated due to having to
run with $CWD as the temporary directory.

Use QStandardPaths  to find the  writable data directory  where needed
rather than passing it around  between objects. This now works because
the $CWD hasn't been changed.

Do away with the CMake option WSJT_STANDARD_FILE_LOCATIONS as it is no
longer needed.

3a5edb5af5 FFTW wisdom is now built into jt9[.exe].
New optional argument to jt9: -w patience
Default is patience = 1

Example timing measurements for 130610_2343.wav:

patience  plan   execute
          (s)      (s)
-----------------------------------------------
   0      0.01     1.25  FFTW_ESTIMATE
   1      0.69     1.25  FFTW_ESTIMATE_PATIENT
   2     16.97     1.15  FFTW_MEASURE
   3    390.88     1.15  FFTW_PATIENT

Conclusions, consistent with expectation based on past experience
with similar FFTs:
  - First decode (in each mode) with patience = 2 is slow.
  - Speed advantage of patience = 2 is small but measurable.
  - No measurable advantage in using patience > 2.

Present mainwindow.cpp has "-w 1" hard-wired.

f07a960e2d Several decoder optimizations, including implementation of FFTW wisdom.
Notes:
1. Equivalents of wisdom1.bat will be needed for *nix and OS X.  (The
   version now added to the source .../lib directory is an example only.)
2. Installers should offer to run the wisdom1[.bat] script at installation
   time.
3. wisdom1[.bat] and fftwf-wisdom[.exe] must be installed in .../bin directory
