Jeff Squyres c7c3de87f5 Add ummunotify support to Open MPI. See
http://marc.info/?l=linux-mm-commits&m=127352503417787&w=2 for more
details.

 * Remove the ptmalloc memory component; replace it with a new "linux"
   memory component.
 * The linux memory component will conditionally compile in support
   for ummunotify.  At run-time, if it has ummunotify support and
   finds run-time support for ummunotify (i.e., /dev/ummunotify), it
   uses it.  If not, it tries to use ptmalloc via the glibc memory
   hooks. 
 * Add some more API functions to the memory framework to accomodate
   the ummunotify model (i.e., poll to see if memory has "changed").
 * Add appropriate calls in the rcache to the new memory APIs to see
   if memory has changed, and to react accordingly.
 * Add a few comments in the openib BTL to indicate why we don't need
   to notify the OPAL memory framework about specific instances of
   registered memory.
 * Add dummy API calls in the solaris malloc component (since it
   doesn't have polling/"did memory change" support).
