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. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6324 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
