If user sets HCOLL_EXTERNAL_UCM_EVENTS=1 then we try init opal
memory framework and register a mem release cb. Otherwise, rely on ucx.

Atomic lock must progress local worker while obtaining the remote lock,
otherwise an active message which actually releases the lock might not
be processed while polling on local memory location.

SLURM 19 discontinued the use of --cpu_bind (and changed it to
--cpu-bind). There's no easy way to test at run time which one is
accepted, so set the environment variable SLURM_CPU_BIND to "none",
which should do the same thing as the srun CLI parameter.

- in some cases realloc operation may be completed without
allocation of new buffer (and without additional data copy)
- added logic to reallocate buffer inplace if possible

Remove compatibility code for multiple versions of BTL_IN_OPAL,
BTL_VERSION, and RCACHE_VERSION. This stuff was really only necessary
when we were actively swapping code between multiple release branches
that had large variations in core OMPI infrastructure. These large
variations have now been around for quite a while, so the need for
this "compat" layer is significantly reduced. It hasn't been removed
simply because a few of the "compat" names a slightly more friendly
than the real names (e.g., the SEND/RECV/PUT names).

This commit fixes an error in the 32-bit compare-and-swap atomic support
for Aries networks. The code was incorrectly using the non-fetching
version of cswap which was causing the routing to return
OPAL_ERR_BAD_ARG.

The rdma_frag attached to the send request was not correctly released
upon request completion, leaking until MPI_Finalize. A quick solution
would have been to add RDMA_FRAG_RETURN at different locations on the
send request completion, but it would have unnecessarily made the
sendreq completion path more complex. Instead, I added the length to
the RDMA fragment so that it can be completed during the remote ack.
Be more explicit on the comment.
The rdma_frag can only be freed once when the peer forced a protocol
change (from RDMA GET to send/recv). Otherwise the fragment will be
returned once all data pertaining to it has been trasnferred.

In OMPI 2.1.2, buildrpm.sh could work with a value of rpmtopdir that was
set in the environment. In newer versions this is no longer true,
causing such values to be ignored. This patch adds a new argument to
buildrpm.sh, -R, which allows the user to specify where to build the
RPMs.
