Jeff Squyres c7282855e7 Fixes trac:659
This commit fixes several aspects regarding MPI conformance of requests.

 * Eliminate the last argument of ompi_errhandler_request_invoke(); we
   ''always'' want to invoke the back-end exception handler with the
   real error code.
 * Make it clear in comments that we only invoke the ''first''
   exception in a given array of requests, even if there's more than
   one request with a non-MPI_SUCCESS value for MPI_ERROR.
 * Defer the freeing of requests upon exception in the back-end
   functions to MPI_WAIT* and MPI_TEST* until later; the requests are
   kept so that we know what handler to invoke when we actually invoke
   the exception.  After figuring that out, ''then'' we free requests
   with pending exceptions on them.
 * Clean up return codes from the back-end MPI_TEST* and MPI_WAIT*
   functions.
 * Slightly modify ompi_errcode_get_mpi_code() to return unity if it
   receives an MPI error code (vs. an OMPI error code).
