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.
