This commit expands the OPAL_THREAD macros to include 32- and 64-bit
atomic swap. Additionally, macro declararations have been updated to
include both OPAL_THREAD_* and OPAL_ATOMIC_*. Before this commit the
former was used with add and the later with cmpset.

This commit adds opal_using_threads() protection around the atomic
operation in OBJ_RETAIN/OBJ_RELEASE. This resolves the performance
issues seen when running psm with MPI_THREAD_SINGLE.
To avoid issues with header dependencies opal_using_threads() has been
moved to a new header (thread_usage.h). The OPAL_THREAD_ADD* and
OPAL_THREAD_CMPSET* macros have also been relocated to this header.
This commit is cherry-picked off a fix that was submitted for the v1.8
release series but never applied to master. This fixes part of the
problem reported by @nysal in #1902.

The max inline send size on a queue pair is not available until after
the endpoint is connected. Before this commit the send flags
(including the inline flag) were set before this value was
initialized. This commit moves setting the send_flags down to
mca_btl_openib_put_internal which is only called after the endpoint is
connected. This fixes a bug when using osc/rdma.

This commit fixes a bug in the pmix2x client code where a loop
variable is not correctly incremented. This was leading to hangs and
crashes when creating intercommunicators. Also fixed two double
increments in other loops.

Blocking fence is used in yalla del proc. Native pmix exposes this functionality.
We need to expose it for SLURM's s1/s2 components as well.
Also this commit fixes uninitialized `rc` in fencenb's of both
components.
Thanks Jeff for the guidance

in order to keep this commit easy to review, some AS_IF([...]) were replaced with
AS_IF([false], ...) or AS_IF_([true], ...)
these will be removed and re-idented in a subsequent commit
pmix cannot be built on alpine linux because of some missing includes.
uid_t and gid_t are defined in unistd.h or sys/types.h, and unistd.h
is not indirectly pulled under alpine linux, so do it manually.

This commit fixes a long standing bug in rdmacm. It is required that
the thread that calls mca_btl_openib_endpoint_cpc_complete holds the
endpoint lock. This was not the case for rdmacm. This causes debug
builds to abort. This change also required changing
mca_btl_openib_endpoint_send_cts to require the endpoint lock to be
held when calling.

This commit is an attempt to fix a hang in finalize of rdmacm. This fixes
a path where no rdmacm client is found for an endpoint.

This commit fixes a segmentation fault that occurs if a device can be
initialized but not used. In this case the devices_count is not equal
to the number of usable devices in the devices pointer array.
Thanks to @artpol84 for tracking this down.

This commit fixes a race condition discovered by @artpol84. The race
happens when a signalling thread decrements the sync count to 0 then
goes to sleep. If the waiting thread runs and detects the count == 0
before going to sleep on the condition variable it will destroy the
condition variable while the signalling thread is potentially still
processing the completion. The fix is to add a non-atomic member to
the sync structure that indicates another process is handling
completion. Since the member will only be set to false by the
initiating thread and the completing thread the variable does not need
to be protected. When destoying a condition variable the waiting
thread needs to wait until the singalling thread is finished.
Thanks to @artpol84 for tracking this down.
