Jeff Squyres 2f936c4597 Fixes trac:549
Had group discussion about this on the weekly call.  The decision was
that we should pass the real error code to the back-end exception
handler because it's pretty useless to pass MPI_ERR_IN_STATUS to the
back-end exception handler (because exception handlers don't have
access to the request or the status - this has potential issues for
fault tolerance kinds of scenarios).  So in TESTALL, TESTSOME,
WAITALL, and WAITSOME, we examine the error code and if it's not
MPI_SUCCESS, return MPI_ERR_IN_STATUS.

This commit was SVN r12389.
