Add debug
Add client/server test
Per conversation with Josh H., remove the stale rsh component from the filem framework. Let the "raw" component do the job.
Update platform files
Changing some of the MPI_ functions to ompi_ equivalents.
Defensive programming: add a constructor for opal_if_t that zeros
everything out before using it.  

This is not in response to any known bug, but rather just a
pre-emptive, defensive move to help prevent bugs in code that forgets
to initialize a field.
Also support getting the MAC and MTU.
Add public functions for retrieving the MAC and MTU (paired with
r28344).
Fix some compile errors in CUDA-aware code that has crept in.
Fix an error in a test in the libevent configure.ac that we introduced - there are two brackets around the entire test code, so no need for double-brackets around the array indices within it

cmr:v1.7.2
Update libevent to 2.0.21-stable, but currently ignore it for all but those testing it
Somebody (accidentally) removed the instructions for updating libevent releases in OMPI, so replace them with at least an outline on how to do it.
Got this wrong while replacing MPI function with OMPI functions. Fixed it now.
Sync NEWS
Properly remove the object from the list prior to releasing it when an error is encountered
Add some debug output
update LANL platform files
Per RFC add initial support for the MPI 3.0 tools interface.

Current MPI_T support:
  - Full cvar interface.
  - Full categories interface.
  - No pvar support at this time.
Add file missing from last commit
Fixed macro definition order in MXM component headers
