Remove the obsolete and largely unused orte_system_info structure. The only fields that were used in that struct were nodeid and nodename - these have been transferred to the orte_process_info structure.
...
Only one place used the user name field - session_dir, when formulating the name of the top-level directory. Accordingly, the code for getting the user's id has been moved to the session_dir code.

get the sm optimized allreduce working for all but user defined
...
operations. Added to the reduction operations a set of reduction
functions that take 2 input buffers and one output buffer to avoid
some extra memory copies. These can't be used with user defined
operations. The intel c collective suite passes both original, and
new (new, not the user defined operations).
