We should invoke OBJ_CONTRUCT/OBJ_DESTRUCT only on regular requests
(which are embedded inside UCX requests) and for the completed request.
Persistent requests are already constructed/destructed by the free list.
This fixes an assertion in ompi_request_destruct.
Writing to the pml_monitoring_flush variable will set the filename of
the output file.
Stopping a session for the pml_monitoring_flush will force the
generation of the nobitoring output file (as long as the filename
is not NULL).
To reset the monitoring, une has to bind the pml_monitoring_flush to a
session.

Per Brice suggestion make all data count and message length be

counting or not the collective traffic as a separate entity. The need
for such a PML is simply because the PMPI interface doesn't allow us to
identify the collective generated traffic.
This commit add protection to the group, ob1, and bml endpoint lookup
code. For ob1 and the bml a lock has been added. For performance
reasons the lock is only held if a bml or ob1 endpoint does not
exist. ompi_group_dense_lookup no uses opal_atomic_cmpset to ensure
the proc is only retained by the thread that actually updates the
group.

This commit changes the priority of mtl components to be relative to
pml/ob1 and updates the mtl interface to expose this priority. cm now
sets its own priority based on the priority of the selected mtl
component.

This commit removes code that checks the ob1 priority vs the previous
priority. The previous priority is meaningless here and may only cause
ob1 to disable itself when it shouldn't.

This patch removes a priority check that disables cm if the previous
pml had higher priority. The check was incorrect as coded and is
unnecessary as we finalize all but one pml anyway.

Once a FIN control message is appended to the pending list,
the ob1 PML attempts to send the FIN again in the `mca_pml_ob1_process_pending_packets` function.
But if the PML failed to sent the FIN again, the `mca_pml_ob1_send_fin`
function creates a new `mca_pml_ob1_pckt_pending_t` object and the
old object is not retured to the free list.
Fix CID 1315271: Constant expression result
The intent of this conditional is to not produce a peruse event for
probe or mprobe requests. Coverity is correct that the expression is
always true. Changed the || to && to fix. Also moved the conditional
within an OMPI_WANT_PERUSE to ensure the conditional is not evaluated
if peruse is disabled.

This commit adds support to the pml, mtl, and btl frameworks for
components to indicate at runtime that they do not support the new
dynamic add_procs behavior. At the high end the lack of dynamic
add_procs support is signalled by the pml using the new pml_flags
member to the pml module structure. If the
MCA_PML_BASE_FLAG_REQUIRE_WORLD flag is set MPI_Init will generate the
ompi_proc_t array passed to add_proc from ompi_proc_world () instead
of ompi_proc_get_allocated ().
Both cm and ob1 have been updated to detect if the underlying mtl and
btl components support dynamic add_procs.

This commit contains the following changes:
- pml/ob1: use the bml accessor function when requesting a bml
endpoint. this will ensure that bml endpoints are only created when
needed. for example, a bml endpoint is not requested and not
allocated when receiving an eager message from a peer.
- pml/ob1: change the pml_procs array in the ob1 communicator to a
proc pointer array. at the cost of a single level of extra
redirection this will allow us to allocate pml procs on demand.
- pml/ob1: add an accessor function to access the pml proc structure
for a given peer. this function will allocate the proc if it
doesn't already exist.

Bring Slurm PMI-1 component online
Bring the s2 component online
Little cleanup - let the various PMIx modules set the process name during init, and then just raise it up to the ORTE level. Required as the different PMI environments all pass the jobid in different ways.
Bring the OMPI pubsub/pmi component online
Get comm_spawn working again
Ensure we always provide a cpuset, even if it is NULL
pmix/cray: adjust cray pmix component for pmix
Make changes so cray pmix can work within the integrated
ompi/pmix framework.
Bring singletons back online. Implement the comm_spawn operation using pmix - not tested yet
Cleanup comm_spawn - procs now starting, error in connect_accept
Complete integration
This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).
