grpcomm_base_allgather.c

Effectively revert the orte_output system and return to direct use of opal_output at all levels. Retain the orte_show_help subsystem to allow aggregation of show_help messages at the HNP.

grpcomm_base_close.c

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.
