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.

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!
