in order to keep this commit easy to review, some AS_IF([...]) were replaced with
AS_IF([false], ...) or AS_IF_([true], ...)

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.
Thanks N.L.K Nguyen for the report

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.

The way the gni btl is currently coded,
it will run completely out of gas on KNL at
123 processes/node. Since there are bound to be
those who try to run a MPI process/hyperthread
on KNL nodes, the fma sharing mode needs to be requested.

The rdma_disconnect function specifies that both the server and client
should call rdma_disconnect. The code was not calling rdma_disconnect
on an endpoint if the event came before the endpoint finalization.

Before dynamic add_procs the openib_btl_size_queues was called exactly
once for non-dynamic jobs. Now the function is called on each new
connection so the calculation was wrong. Re-wrote the function to
correctly calculate the CQ size and only attempt to adjust the CQ if
the requested size has changed. This fixes a bug when using the openib
btl on psm2 hardware that is caused by the time needed to resize a
CQ. The overhead was causing udcm to timeout and fail.
