The RML is comfortable with zero-byte payloads, so don't pack something we don't need

Fix the allgather and allgather_list functions to avoid deadlocks at large node/proc counts. Violated the RML rules here - we received the allgather buffer and then did an xcast, which causes a send to go out, and is then subsequently received by the sender. This fix breaks that pattern by forcing the recv to complete outside of the function itself - thus, the allgather and allgather_list always complete their recvs before returning or sending.

grpcomm_types.h

Fix xcast so it works in multi-node situations where the user specifies a particular mode to use (e.g., direct).
