base.h

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_base_allgather.c

Fix unity routed component by adding xcast of proc data to the daemons. This enables daemons to complete the revised modex procedure by forwarding their collected modex info to the rank=0 proc.
