nonzero status (we polled other MPI implementations since one one in
the OMPI community had a concrete opinion on what behavior to do here
-- all other MPI's seem to adhere to this behavior, too).
This commit adds an MCA parameter that allows us to tell ORTE to
''not'' kill jobs when a process exits with a status of 77, meaning
the GNU testing standard of "this test was skipped". In all the OMPI
tests, all procs will either return 77 or not. So if they all return
77, mpirun won't consider it an error, but will still return an exit
status of 77 (so that MTT can know that the test was cleanly skipped).

POWER6 and POWER7 systems.
This is still an unresolved issue; the Linux kernel does not expose
enough (correct) information for OMPI to be able to do anything
rational. IBM is working on it.

* Remove paffinity, maffinity, and carto frameworks -- they've been
wholly replaced by hwloc.
* Move ompi_mpi_init() affinity-setting/checking code down to ORTE.
* Update sm, smcuda, wv, and openib components to no longer use carto.
Instead, use hwloc data. There are still optimizations possible in
the sm/smcuda BTLs (i.e., making multiple mpools). Also, the old
carto-based code found out how many NUMA nodes were ''available''
-- not how many were used ''in this job''. The new hwloc-using
code computes the same value -- it was not updated to calculate how
many NUMA nodes are used ''by this job.''
* Note that I cannot compile the smcuda and wv BTLs -- I ''think''
they're right, but they need to be verified by their owners.
* The openib component now does a bunch of stuff to figure out where
"near" OpenFabrics devices are. '''THIS IS A CHANGE IN DEFAULT
BEHAVIOR!!''' and still needs to be verified by OpenFabrics vendors
(I do not have a NUMA machine with an OpenFabrics device that is a
non-uniform distance from multiple different NUMA nodes).
* Completely rewrite the OMPI_Affinity_str() routine from the
"affinity" mpiext extension. This extension now understands
hyperthreads; the output format of it has changed a bit to reflect
this new information.
* Bunches of minor changes around the code base to update names/types
from maffinity/paffinity-based names to hwloc-based names.
* Add some helper functions into the hwloc base, mainly having to do
with the fact that we have the hwloc data reporting ''all''
topology information, but sometimes you really only want the
(online | available) data.

Fix the state machine to support multiple jobs being simultaneously launched as this is not only required for mapreduce, but can happen under comm-spawn applications as well.

point home that they're deprecated
* Similarly, make mpif77-wrapper-data.txt be a sym link to
mpifirt-wrapper-data.txt (ditto with mpif90)
* Make new mpif77.1 and mpif90.1 man pages that say that they're
deprecated; use mpifort instead
