Joe Taylor 846ddf9039 1. Clean up GUI features releted to message averaging and deep search.
2. Make averaging and DS separately selecteble.
3. Clear nftt and avemsg on Clear Avg.
4. Allow fer65 to handle message averaging.

Joe Taylor 331402213a Several changes for single-decode behavior:
1. Use "f" to flag FT decodes, 'h' for hinted decodes.
2. Let "Experience-based" checkboxes activate hinted decoding.
3. Singls-sequence decodes go to left window, average decodes to right.

Joe Taylor 767a9452e6 1. Use Lorentzian profile for smoothing (but not yet for message averaging).
2. Add ability to set ndepth and do message averaging ti fer65.
3. Correct SNR values for measured Doppler width.
4. Comment out the "write(62..." diagnostics.

Joe Taylor 533bb81220 Various changes to JT65 decoding, all potentially temporary.
1. Measure Doppler width by fitting a (modified) Lorentzian.
2. Don't call "slope" in sync65().
3. New definition of "sync1".
4. Get snr from sync1.

factor 2*sqrt(log(2)).

Bill Somerville 4de778c4e7 Reverting r6531 and replacing with correct fix
The WSPR  message is unpacked  into a symbol  per byte array  which is
processed  by  encoding a  whole  number  of  bytes of  message,  this
requires the output  array to be bigger than the  number of symbols to
accommodate  extra values  that are  not part  of the  message due  to
rounding up to whole bytes. I.e.  176 (11*8*2) elements to contain the
162 symbols.

Also use assumed shaped for dummy argument arrays where possible.

If a  Fortran procedure has  an interface declaration,  which includes
all procedures exported  from modules, then dummy  arguments should be
declared as assumed shape if possible.  This allows compiler generated
array bounds checking and compile time array shape checking.

Bill Somerville 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.

Bill Somerville f416a52def Make Fortran profiling timer function a callback with a default null implementation
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.

Bill Somerville 93b2f4164a Improve the randomness of the srand seed generator
XOR:ing the time since epoch in seconds with the PID fails for processes
started every second since the PID and time increment in step regularly in
this scenario and therefore give identical seeds. Thanks to Steve K9AN for
spotting this subtle flaw.

Bill Somerville 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.
