Joe Taylor a93e55fef0 Improved, simplified sort routine; faster and better "flatten"
procedure; better window functions for some FFTs, resulting in
better decoder performance; User-selectable colors for backgrounds
of decoded messages.  NB: more testing is desirable!

Joe Taylor c7faf40d34 Need space for more calls to timer().

Joe Taylor 010f85ec70 Further algorithmic tweaks in the JT9 decoder.
More detailed message to come, with comparative timing statistics.

Joe Taylor 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!

Joe Taylor 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.

Joe Taylor 60955db247 Resurrect jt9sim, in case we need it.

Joe Taylor 3228cc85e5 New Makefile.jtsdk allows easy building of jt9.exe from command line.
(Many changes still needed to wsjtx.pro, in order to build from
within QtCreator.)
