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).
