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.

ready for release in a future v1.6 release.
