the decoders. Also, an experimental change to the FT4 decoder to base
AP decoding passes on 4-symbol block detection instead of single symbol
detection. This provides about 1 dB improvement on the AWGN channel.
Sensitivity changes on other channels are TBD.

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.

Also use correct C binding and have compilers determine sizes and
offsets.
The wsjtx.exe program now owns the decoder shared data that is shared
with symspec. It is now in struct dec_data, still a global variable
for now but hopefully a MainWindow member variable soon.
The struct dec_data (in both C/C++ and Fortran) has a sub structure
with the decoder parameters which enables copying and manipulating a
lot cleaner.
New of changed types of shared data must still be modified in
commons.h and a new file lib/jt9com.f90, they must stay in sync as a
pointer to the structure is passed between C and Fortran.
