[ofiwg] Blue Gene /Q OFI Libfabric provider open source contribution to OFIWG git repo

The first rc for the 1.4 release will occur soon (target is this week).  So, merging it after the 1.4 release seems preferable.  But you can submit a PR with the changes now.
 
For the PR, it is helpful if you separate out all changes to the libfabric core into its own commit(s).
