Things got a little out of whack and we weren't actually processing the map-by modifiers, plus an error crept into the display of the binding report. So clean those up.
Thanks to @tonyreina for the error report

Get the OMPI rte/pmix component working. This was tested using PRRTE as the RM, configuring OMPI using:
* autogen --no-orte
* with external libevent, external hwloc, and external PMIx master
* configuring PMIx master with the same libevent and hwloc
* execute the application using PRRTE's "prun" launcher, which has the same cmd line as ORTE's mpirun
Note that PMIx master appears to have a bug in the event notification system that caches job termination events. Thus, the first execution runs fine, but subsequent executions cause an "abort" when the OMPI default error handler is invoked upon notification of the prior job's termination. Will work that separately.

Simple MCA vars for ext1, ext2, and pmix3 components to reflect what
the underlying PMIx library version is. For example:
```

This commit fixes the case when local client asks for the key from the
process on the remote node. The local server don't have commit count for
remote ranks, it is maintained by another PMIx server, so commit count
should be ignored for remote requests.

The current code path for PMIx_Resolve_peers and PMIx_Resolve_nodes executes a threadshift in the preg components themselves. This is done to ensure thread safety when called from the user level. However, it causes thread-stall when someone attempts to call the regex functions from _inside_ the PMIx code base should the call occur from within an event.
Accordingly, move the threadshift to the client-level functions and make the preg components just execute their algorithms. Create a new pnet/test component to verify that the prge code can be safely accessed - set that component to be selected only when the user directly specifies it. The new component will be used to validate various logical extensions during development, and can then be discarded.

(cherry picked from commit 456ac7f7af3d9ba09888e3c899eb001daaa24aef)
This is a point-in-time update that includes support for several new PMIx features, mostly focused on debuggers and "instant on":
* initial prototype support for PMIx-based debuggers. For the moment, this is restricted to using the DVM. Supports direct launch of apps under debugger control, and indirect launch using prun as the intermediate launcher. Includes ability for debuggers to control the environment of both the launcher and the spawned app procs. Work continues on completing support for indirect launch
* IO forwarding for tools. Output of apps launched under tool control is directed to the tool and output there - includes support for XML formatting and output to files. Stdin can be forwarded from the tool to apps, but this hasn't been implemented in ORTE yet.
* Fabric integration for "instant on". Enable collection of network "blobs" to be delivered to network libraries on compute nodes prior to local proc spawn. Infrastructure is in place - implementation will come later.
* Harvesting and forwarding of envars. Enable network plugins to harvest envars and include them in the launch msg for setting the environment prior to local proc spawn. Currently, only OmniPath is supported. PMIx MCA params control which envars are included, and also allows envars to be excluded.

Resolve a race condition between registering for a file to be removed upon termination and actual creation of that file by providing attributes that identify whether the path is a file or directory. This removes the need for PMIx to detect the difference.

If available, have apps use registration capability to cleanup their session directories. Setup capability for vader to register its shared memory file location - let someone familiar with that code do so.

The problem is that the waiting thread is cycling using OMPI_LAZY_WAIT_FOR_COMPLETION so it can exercise opal_progress. This probably isn't as critical for the modex step, but definitely necessary for the barrier at the end of mpi_init. The problem this creates is that the lazy macro exits as soon as "active" becomes false, and then we destruct the lock.
However, wakeup_thread sets "active" to false - and then calls the condition broadcast to wakeup any waiting threads. So there is a race condition between that broadcast and the lock destruct.
Add OPAL_ACQUIRE_OBJECT and OPAL_POST_OBJECT memory barriers to help protect against thread race conditions on some platforms
