70b84478f0 Add WW_DIGI to the special activities section. Make necessary changes to
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.

d431e2cecd Restructuring in preparation for direct decoder invocation from wsjtx
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.

d5bc774641 Get rid of jt9com and npar common blocks
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.
