c75c4aefda Further improvements to JT9 decoder.
Better AFC (wider range of possible drifts; more accurate DT alignment).
Better definition of metric tables used by Fano decoder.
Zero-centeres soft symbols, instead of offset +128.
Tuned several empirical parameters.

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!

3fdde76420 The "big FFTs" should be computed only once for each new set of Rx data.
This requires setting newdat=0 after the big FFT is computed.  In the OMP
code this must be done separately for each mode; so new variables newdat9 
and newdat65 have been defined.  Both are set to "newdat", the value
forwarded from the GUI, each time jt9[_omp][.exe] goes into action.

127f72f3ad Remove redundant copy of large array in JT9 decoder
Also moved  the same large array  from stack to heap  which along with
other prior  changes now allows  the Windows jt9 OpenMP  executable to
run with a default stack size again.

This also removes a crash on the Mac version which was probably due to
excessive stack usage.

Net result is an even faster JT9 decoder.

d1a1510fc8 Make output arguments of decoders shared between threads
This is only a temporary fix  becuase if both decoders were to produce
results  that need  accumulating  e.g. number  of  decodes, then  more
complex code to merge the results would be needed.

1271243952 Thread safe lib/timer.f90
Accounts for each traced call per thread and accumulates by rolling up
calls with an identical call chain before printing the statistics. The
print now accounts for function calls  in their call chain so the same
function will be reported more than  once if it is called in different
places.

e791efb5b8 First attempt at a thread safe lib/timer.f90
This  tries  to  account  for  function  calls  in  different  threads
separately by decorating  the function name with the  thread number it
is  running in.  This may  not be  the best  strategy for  performance
timing but it is  the easiest way of making it thread  safe that I can
see.

ffdeafe3bb Build an OpenMP version of jt9 where possible
This change  introduces the program jt9_omp  which is a testbed  for a
multi-threaded version of the jt9 decoder program. The program jt9_omp
should be  a directly substitutable for  jt9 except that JT65  and JT9
decodes are computed in parallel.

Also enable  the OpenMP directives in  decoder.f90 - note this  is not
yet a working multi-threaded decoder and the existing jt9 is still the
correct decoder to be used in WSJT-X.

Increased the available  stack size for jt9_omp.exe as this  is a hard
limit on  Windows and  the default  is not big  enough for  the OpenMP
version of jt9.

Also  Fortran  array  bounds  checking is  now  disabled  for  Release
configuration builds so as to improve performance a little.

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!
