…ring neither have nans first
The MPI_ibsend calls in edyn_mpi were generating MPI tags by concatenating the source and destination PE numbers which overflows the maximum MPI tag size (~65536) - the original tag numbers were around 10M (e.g., 12341235) Since communicators in mp_mag_jslot is scoped to the cols_comm sub-communicator for a single magnetic longitude column (up to nmagtaskj-1), there is no need for globally unique tags. The code has been updated to use sender rank number which is unique within the sub-communicator (tij) which is isrc at the receiver end.
Bring in a couple of misc changes: MT and LT ne16pg3 namelist defaults for dycore and inic; remove unused routines
