If the state of the request is not set to OMPI_REQUEST_ACTIVE
then MPI_Test would immediately signal such request completed
while hcoll may still be working on it.

If atomics are not globally visible (cpu and nic atomics do not mix)
then a btl endpoint must be used to access local ranks. To avoid
issues that are caused by having the same region registered with
multiple handles osc/rdma was updated to always use the handle for
rank 0. There was a bug in the update that caused osc/rdma to continue
using the local endpoint for accessing the state even though the
pointer/handle are not valid for that endpoint. This commit fixes the
bug.

Optimizing put aggregation in the presence of threads will require a
redesign of the code. For now just ensure that put aggregation is
turned off when MPI_THREAD_MULTIPLE is enabled.

Update the configure logic for the new pmix120 component
ckpt
Get the pmix120 component to work - still not really registering or handling notifications, but infrastructure now operates
Cleanup some of the symbol scopes, and provide a more comprehensive rename.h file. Will pretty it up later - let's see how this works
Cleanup the rename files to use the pretty macros
When mtl-portals4 is configured for logical mapping, coll-portals4
must disqualify because it does not yet support logical mapping.
coll-portals4 looks for the endpoint pid to be zero which tells it
that mtl-portals4 is configured for logical mapping. This commit
initializes the endpoint nid/pid to zero for logical mapping.
NOTE: Building with external pmix *requires* that you also build with external libevent and hwloc libraries. Detect this at configure and error out with large message if this requirement is violated.
Closes#1204 (replaces it)
Fixes#1064
A previous commit updated the one-sided code to register the state
region only once. This created an issue when using the scratch lock
with fetching atomics. In this case on any rank that isn't local rank
0 the module->state_handle is NULL. This commit fixes the issue by
removing the scratch lock and using a fragment pointer instead.

accelerate message queue lookups if the lookups have
the proper tag&mask layout. OpenMPI should follow
PSM2's preferred tag&mask spec, so that PSM2 can provide
a performance benefit.
Remove send of the extra message. This bug hase triggered on
MPICH/coll/nbicbarrier test. In this test a series of communicators
are created.
This extre-message was reseived after original communicator was destroyed
and queued into non_existing_communicator_pending. When new completely
unrelated communicator with the same id as original was created this message
was pushed into the frags_cant_match queue and caused seq numbers skew and hang.
