George Bosilca 82d1d5d785 The patch for "Unexpected message queue for unknown CID's required" ticket #1460.
I'm unable to split it in two parts, my patch and Edgar's one. So I just update
copyright information for both of us.
What this patch do:
- it use the unexpected queue create by commit r19562 to dispatch the
  unexpected message to the right communicator (once this communicator
  is created and initialized).
- delay the PML comm_add until we have the context_id for the new communicator.
- only do the PML comm_add on processes that really belong to the new
  communicator. Please read the lengthy comment in the source code for the
  reason behind this.

This commit was SVN r19929.
