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!

3a8232b113 Made a start at implementing an option to use multi-threaded FFTs.
New command-line option for jt9: [-m nthreads].  Default is nthreads=1.
Also refactored a loop in filbig.f90 that was taking far too much
time.

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.

Fix astro status file azel.dat formatting.

20ded259d8 Decode from disk sets npatience = 2.
This means that the first decode from a saved data file will be slow,
but the saved wisdom for the decoded mode(s) will be better than
for the default npatience = 1.  All subsequent decodes in the same 
mode(s) will take advantage of the newly saved wisdom.

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

4fea8ebd0c Optimizations of JT9 and JT65 decoders; change clock in timer routine.
Both decoders now have slightly better performance and faster
execution.  The rare "duplicate decodes" in JT9 were eliminated.
On Windows, at least, calls to f90 routine system_clock() do not
provide correct wall time increments.  Changed to using secnds()
instead.

1ff68d5098 Make/qmake tweaks
The lib/Makefile.MinGW makefile  has been enhanced to link  to the DLL
version of fftw3  which is the normal version of  the library that you
get with the Windows installer.

The library is  located by passing the FFTW3_DIR variable  on the make
command line. For example on my system:

	$ # In a MinGW console
	$ cd ~/src/wsjtx/lib
	$ make QT_DIR=/c/Tools/Qt/5.2.1/mingw48_32 \
	>  FFTW3_DIR=/c/Tools/fftw-3.3.3-dll32-2

Similarly with the qmake project:

	$ # In a Qt MinGW 32-bit console
	$ cd ~/src/wsjtx
	$ qmake \
	>  HAMLIB_DIR=c:/test-install/hamlib/mingw48_32 \
	>  FFTW3_DIR=c:/Tools/fftw-3.3.3-dll32-2
	$ mingw32-make

0e96882d8b Improve the way messages with compound calls are automatically generated.
Routine packmsg now tries the shortlist (Type 1 prefix or suffix) first.
Then it tries to to make a valid message using a Type 2 prefix or suffix.
If both fail, it packs the first 13 characters as a free-text message.

The GUI now generates the most useful messages with compound callsigns
of all valid types.
