This commit adds support for atomic operations as well as rdma for
systems without rdma support. This support is implemented using an
internal send tag.

added pointer to this method into mca_spml_ucx_t structure

moving some code from fs/ufs into fs/base. The benefit of this approach is
that fs components that are fundamentally based on posix I/O (and only differ
in some non-posix functionality such as setting stripe size, or which hints
are being supported) can avoid having to replicate the same code over and
over again. First beneficiary is the lustre fs component, but more
are to follow soon.

Intentionally do not mark some MPI-1 function pointer typedefs as
`__mpi_interface_removed__` because we have to use them in prototyping
some MPI-1 functions when `--enable-mpi1-compatibility` is used.
Fixes#5357.

The current cast is *functional*, but isn't really the way it should
be done. This commit makes the cast the way it should be done.

Fix two facepalms:
1. The "uint32" in the hash map functions refer to the *key* size, not
the *value* size. The values are always 64 bits.
2. Pass the straight value to the "set" functions -- not the pointer
to the value.

This commit changed the way btl/ofi call progress. Before, we force
progression with every rdma/atomic call. This gives performance boost in
some case and slow down on others. Now we only force progression after
some number of rdma calls which result in better performance overall.
Also added new MCA parameter 'mca_btl_ofi_progress_threshold' to set
the threshold number. The new default is 64.
Also:
Added FI_DELIVERY_COMPLETE to tx_rtx flags to ensure that the completion
is generated after the message has been received on the remote side.

This commit improves the injection rate and latency for RDMA
operations. This is done by the following improvements:
- If C11's _Thread_local keyword is available then always use the
same virtual device index for the same thread when using RDMA. If
the keyword is not available then attempt to use any device that
isn't already in use. The binding support is enabled by default but
can be disabled via the btl_ugni_bind_devices MCA variable.
- When posting FMA and RDMA operations always attempt to reap
completions after posting the operation. This allows us to
better balance the work of reaping completions across all
application threads.
- Limit the total number of outstanding BTE transactions. This
fixes a performance bug when using many threads.
- Split out RDMA and local SMSG completion queue sizes. The RDMA
queue size is better tuned for performance with RMA-MT.
- Split out put and get FMA limits. The old btl_ugni_fma_limit MCA
variable is deprecated. The new variable names are:
btl_ugni_fma_put_limit and btl_ugni_fma_get_limit.
- Change how post descriptors are handled. They are no longer
allocated seperately from the RDMA endpoints.
- Some cleanup to move error code out of the critical path.
- Disable the FMA sharing flag on the CDM when we detect that there
should be enough FMA descriptors for the number of virtual devices
we plan will create. If the user sets this flag we will not unset
it. This change should improve the small-message RMA performance by
~ 10%.

This commit adds a new btl for one-sided and two-sided. This btl
uses the uct layer in OpenUCX. This btl makes use of multiple uct
contexts and per-thread device pinning to provide good performance
when using threads and osc/rdma. This btl has been tested extensively
with osc/rdma and passes all MTT tests on aries and IB hardware.
For now this new component disables itself but can be enabled by
setting the btl_ucx_transports MCA variable with a comma-delimited
list of supported memory domains/transport layers. For example:
--mca btl_uct_memory_domains ib/mlx5_0. The specific transports used
can be selected using --mca btl_uct_transports. The default is to use
any available transport.

The osc/rdma module did not wait for all pending atomics to complete
before tearing down. This could lead to weird issues as the target
location may no longer be registered or allocated.
