* Add support for using modex to exchange NID/PID pairs when using Portals4.
Rather than try to support a bunch of lightweight environments like I did with the Portals3 code, always use the "modex" and hack the grpcomm for the SHMEM implementation to return the right nid/pid for a remote process by "magic". This commit was SVN r24733.
