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.
