Jeff Squyres e02114dcf3 Fixes trac:529.
* Create a new request type: NOOP (described below)
 * For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its
   type to NOOP
 * Ensure that the NOOP requests are OBJ_RELEASE'd when they are done
 * MPI_START looks at the request type; if NOOP, just return success. If
   not, call the PML start() function
 * MPI_STARTALL always pass the entire array of requests back to the PML
   (see next point)
 * Make the PMLs only process PML requests (i.e., ignore/skip anything
   that isn't of type PML -- such as the NOOP requests)
 * Add a little more param error checking in STARTALL
