[Mpi3-ft] Defining the state of MPI after an error

I realize my basic point is rather simple:
If you say MPI state is UNDEFINED after an error, you have part of the
standard done. Simple and clear.
If you say MPI state is DEFINED after certain errors, the standard must
The complexity of identifying and classifying errors and defining the
state after each is mind boggling. The job of implementing and testing
that is even more mind boggling.
BTW - I see no practical problem with mandating that an error code in
class NOT_IMPLEMENTED be considered harmless. I.E. "A subroutine that
returns an error in error class NOT_IMPLEMENTED leaves the MPI library in
the same state as if the call had not been made." That is easy to define
