Brian Barrett 61a090e0d1 Checking for NULL function pointers and direct-call semantics can't work
together, so implement all functions in the MTL interface for all
MTLs.  The only places NULL was still being set was for add_comm/del_comm,
and matched probe, both of which are straight forward to implement (or
return ERROR_NOT_IMPLEMENTED, since the PML can't emulate matched probe).

This commit was SVN r26194.
