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.

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.

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.

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.

More detailed message to come, with comparative timing statistics.

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!

This commit will serve as a benchmark for comparison with new code to
be written.
