73df0d00ef 1. Alt+F8 arms "Call 1st" as if a CQ had been sent. 
2. "Call 1st" label turns red when armed to respond to a caller.
3. Suppress some recognizable false decodes, send them to cumulative file
   "data_dir/false_decodes.txt".
4. Reduce sleep delay in decoder() to 10 ms.

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.
