Several small improvementsasrc

[arango]

Several changes were made to aid in new underway developments:

• Removed the parameter attribute to the declaration of MyMaster in mod_parallel.F.

• Changed from numerical to a variable argument in several MPI function calls in distribute.F:

        Npts=1
        CALL mpi_bcast (A, Npts, MPI_INTEGER, MyMaster, OCN_COMM_WORLD,   &
       &                MyError)
  
  instead of
  
        CALL mpi_bcast (A, 1, MPI_INTEGER, MyMaster, OCN_COMM_WORLD,   q   &
       &                MyError)
  

• Moved the declaration of Adir, Hdir, Hfile, and Rdir from mod_ncparam.F to mod_strings.F.

• Cleaned the use my_fflags in def_info.F, def_mod.F, and read_phypar.F.

• Updated the scripts build.bash and build.sh.
