Jeff Squyres 020efdf1f9 Refs trac:250
This commit essentially caches the invoking comm/win/file on the
ompi_request_t. This, paired with the req_type field, allows us to
retrieve the invoking MPI object and invoke the proper errhandler.

The patch is missing most updates for the MPI-2 one-sided stuff (i.e.,
the patch mainly fixes comms and files); I didn't really understand
that code and didn't want to hazard trying to figure it out when Brian
can probably do it much more quickly.

So #250 will still stay open, pending MPI-2 one-sided updates for this
stuff.

This commit was SVN r12339.
