Ralph Castain 4efddc7b0a 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. ...

Reogranize the grpcomm code a little to provide support for soon-to-come new grpcomm components. The revised organization puts what will be common code elements in the base to avoid duplication, while allowing components that don't need those functions to ignore them.

This commit was SVN r17941.
