Nathan Hjelm fc7397949c btl: require that btls handle descriptor = NULL in the btl_sendi function

The send inline optimization uses the btl_sendi function to achieve lower
latency and higher message rates. Before this commit BTLs were allowed to
assume the descriptor was non-NULL and were expected to return a valid
descriptor if the send could not be completed using btl_sendi. This
behavior was fine until the usage of btl_sendi was changed in ob1. This
commit allows the caller to specify NULL for the descriptor. The affected
btls have been updated to handle this case.

Per the PR and discussion on today's telecon, extend the process name definition as a two-field struct of uint32_t's down to the OPAL layer. This resolves issues created by prior commits that impacted both heterogeneous and SPARC support. This also simplifies the OMPI code base by removing the need for frequent memcpy's when transitioning between the OMPI/ORTE layers and OPAL.
