base.h

Move the daemon collectives out of the ODLS and into the GRPCOMM framework. This removes the inherent assumption that the OOB topology is a tree, thus allowing different grpcomm/routed combinations to implement collectives appropriate to their topology.

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.

grpcomm_base_coll.c

Add a new hierarchical collective grpcomm component that performs modex and barrier across the procs instead of the daemons. Modeled on the tuned collectives. Collective code is in grpcomm base for eventual use by the daemon-based components as well.
