(cherry picked from commit open-mpi/ompi@a02be5e91a)
Cisco wrote a bipartite graph solver to properly solve
interface pair selection for usNIC. Using the reachable
framework, the TCP BTL (and possibly the runtime network
code) can use the graph solver to make more optimal pair
selection. Jeff was happy to have the code more broadly
used, but didn't have time to do the move, hence this
commit.
There are a couple of minor changes to the code compared
to the usNIC version. Obviously, the functions have
been renamed to match naming convention for their new
home. Since it's easier to write unit tests for
util/ code, the unit tests have been made first class
tests run at "make check" time. This last bit required
moving some of the definitions into a new header,
bipartite_graph_internal.h, so that they could be
included in both the library code and the test code.

This test used to have fixed-sized arrays for the mounts that it was
checking. However, we periodically run across machines with more
mounts than can fit into those fixed-size arrays. Rather than
periodically increasing the size of those arrays (after re-discovering
that the error is due to fixed-size arrays), just count how many
entries there are and make arrays that are big enough.
Additionally, add a check to ensure that we don't go over the max size
of the array when reading/filling them.

Now that "make check" siphons off stdout/stderr to logfiles, it's ok
to have output by default from tests. This test fails often enough
that it's useful to see the diagnostic output.
the OPAL and ORTE libraries. This is required by projects such as ORCM
that have their own ORTE and OPAL libraries in order to avoid library
confusion. By renaming their version of the libraries, the OMPI
applications can correctly dynamically load the correct one for their
build."
This reverts commit 63f619f871.
Linux statfs(2) lies about the type of fuse filesystems (it reports
fuse.encfs as an NFS filesystem). So just skip fuse filesystems in
this test until/if we ever care to add some kind of workaround.

On Linux, if this test is run with no command line params, it will run
"mount" and analyze the output (same as it always has).
On all platforms, if you provide one or more command line options,
each command line option is given to opal_path_nfs() and the result is
sent to stdout.

Roll in the ORTE state machine. Remove last traces of opal_sos. Remove UTK epoch code.
Please see the various emails about the state machine change for details. I'll send something out later with more info on the new arch.

zeroes);
if so, use it for bit-operations like opal_cube_dim and opal_hibit.
Implement two versions of power-of-two.
In case of opal_next_poweroftwo, this reduces the average execution
time from 83 cycles to 4 cycles (Intel Nehalem, icc, -O2, inlining,
measured rdtsc, with loop over 2^27 values).
Numbers for other functions are similar (but of course heavily depend
on the usage, e.g. opal_hibit() with a start of 4 does not save
much). The bsr instruction on AMD Opteron is also not as fast.
- Replace various places where the next power-of-two is computed.

This allows us to "make distcheck" with "./autogen.sh -no-ompi"

not present -- because they're OPAL tests and we should treat them
that way).

Also fix a case where if you haven't run "make install", then
opal_show_help_string() will (rightfully) return NULL. So be sure to
handle that case and not segv.

example) because of the fact that libmpi now completely slurps in
libopen-rte (ditto with libopen-rte and libopen-pal).

(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
back the native error code.
* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
(OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
decode 'ret' to get the native error code.
This commit was SVN r23162.
The OPAL SOS framework tries to meet the following objectives:
* reduce the cascading error messages and the amount of code needed to print an error message.
* build and aggregate stacks of encountered errors and associate related individual errors with each other.
* allow registration of custom callbacks to intercept error events.
