[svn-r7416] Major improvement to RMA performance for long lists of operations, an immediate mode accumulate for single ints, store the MPID_Comm within the window, and added a basic performance instrumentation interface that was extensively used to improve the RMA performance (enabled with --enable-g=instr).  With these fixes, MPICH2 can run the one-sided version of the Graph500 benchmark at a respectable if not great rate

[svn-r6115] Use a defined typedef for the message match information; this is needed by the debugger interface

[svn-r5977] Prepare for fix to the debugging interface by providing a name for the message_match_parts structure

This ticket also converts the MPIDI_Request_recv_pending macro into two
macros which have slightly clearer names and usages.  The side effect of
the old macro was very confusing.
