Jeff Squyres 431f940a52 Fixes trac:496
* Add some more error checking to GREQUEST_START
 * Move the error checking in GREQUEST_COMPLETE up to inside the
   MPI_PARAM_CHECK block, where it belongs
 * Invoke the gen request query_fn in all the Right spots (per MPI-2:8.2)
 * Distinguish between grequests created from C and Fortran
 * Use the OBJ system to reference count to release the grequest at
   the Right time and invoke the grequest free_fn properly (see
   lengthy comment in grequest.c above the destructor)
 * Have ompi_grequest_complete() call ompi_request_complete() rather
   than [poorly] copy the contents of ompi_request_complete()
 * Fix Fortran function callback pointer typedefs to use proper
   Fortran types
 * Edit ompi_request_test* and ompi_request_wait* to properly handle
   generalized requests.  This adds an "if" statement in the critical
   path for all the back-end test* and wait* functions :-(,
   but fortunately George took out two "if" statements from the
   critical path last week.  So we're still ahead.  :-)
 * Move ompi_request_test() out of request.h and into request.c (all
   other test* and wait* functions were already in the .c file -- and
   ompi_request_test() was too long to be statically inlined anyway)
