Temporary solution for the PML inconsistency issue discussed in #7475.
This patch address 2 things: first it make the PMIx key optional so that
if we are not in a full modex mode we don't do a direct modex, and
second it get the PML info from the vpid 0 instead of from the local
rank.

Restrict the search to the "immediate" range so at worst we check with
our local server and don't go up to the host daemon.

- Protect against DVM collisions
- Update atomics
- Fix fork/exec and provide better tool support (PMIx)
- Ensure we cleanup completely upon terminating a tool/server that has
dropped rendezvous files

The SM BTL was effectively removed a long time ago. All that was left
was a shell that warned people if they tried to use the SM BTL. For
v5.0, we plan to finally remove this ancient shell (and possibly
replace it with vader).

External pmix installs are frequently in non-standard locations and
the path to their shared libraries are not ldconfig'd in because
there may be multiple pmix installs.
The way the configury was set up prior to this patch, the configuration
would fail soon after the PMIX config stuff was called because it
added some pmix lib stuff to the LDFLAGS, resulting in configury tests
for things that require running the configure test to fail.
This patch avoids this problem by resetting the LDFLAGS and LIBS back
to what they were prior to the run of the external PMIX detection.
The CFLAGS setting is left because there are many places in the ompi
and opal source code where pmix_common.h needs to be included.

Hwloc upstream has fixed a problem with embedded "make distcheck" that
was breaking that surfaced when you ran autogen in an Open MPI
tarball.
This submodule update takes in the upstream hwloc fixes for this
issue.

If someone gives us a namespace that doesn't easily translate to an
integer, we have to create a mechanism for working around the
disconnect. PRRTE has been updated to give us a flag so we know we were
"natively" launched. If we don't see it, then fall back to generating a
hash of the nspace as our jobid. We then have to translate back/forth
between nspace and jobid using a lookup table.
Probably not the right long-term solution, but hopefully helps get us
thru for a bit.
Includes update of PRRTE pointer

This commit fixes an issue in the MCA base variable system. The
code was retrieving the user home directory (from HOME) and
attempting to use it to build a search path for config files.
In this case user-level configuration directories have been
enabled so the appropriate thing to do is to print an error
message and return. This commit makes that change. It does not
ensure that HOME is set correctly.

If you autogen.pl --without-prrte, we wouldn't configure or build PRRTE
support. However, configuring with --disable-internal-rte wasn't working
as it was being ignored. This led to some false errors when compiling
with an earlier PMIx v2.2 release.
That said, there were a couple of places that needed protection against
PMIx v2.2.

Fix a couple of spots in OMPI to resolve warnings. The one in comm_cid
in particular may be responsible for some/all of the comm_spawn issues
as it was passing an incorrect pointer to a macro, thus causing memory
corruption.
Update PRRTE and PMIx to deal with v3/v4 differences.

When a job fails very quickly, it is possible that the spawning tool
won't get notified that the spawn completed prior to be told that the
job terminated. This can cause the tool to "hang" in PMIx_Spawn. Ensure
that PRRTE handles this case by guaranteeing we notify the spawner.
Track both PRRTE and PMIx masters as both have changed, though only the
PRRTE one is involved in this particular fix.

This commit fixes a potential deadlock that can occur between the
memory hooks and region registation. This deadlock occurs because
of a hold and wait error between two mutexes. The first mutex is
the VMA lock used to protect internal rcache/grdma structures and
the reader/writer lock in the interval tree.
In the case of the memory hooks a reader lock is obtained on the
interval tree then the VMA lock is obtained to remove the
registration from the LRU. In the case of LRU evictions the VMA
lock is obtained then the writer lock on the interval tree is
obtained. This leads to the deadlock.
To fix the issue the code that evicts from the LRU has been
updated to only invalidate the registration while the VMA lock
is held then remove the registration from the VMA after the
lock is released. This should completely eliminate the above
deadlock.
