- in sine cases persistent request was deleted during completion
callback, this cause double free of linked UCX request (assert
in debug build or hang in release build)
- UCX request is freed prior completion callback

Per https://github.com/open-mpi/ompi/issues/5031, if the user didn't specify a particular PMIx installation, then default back to the internal version if it is newer than the discovered external one. PMIx doesn't yet provide a full signature so we have to just get as close as possible for now.

Due to decreasing support by vendors/other orgs for the OpenIB BTL,
only look for iWarp/RoCE devices by default. Allow IB HCAs
with ports configured for ethernet.

OFI BTL uses context for completion but never ask for it in
fi_getinfo(3). This commit makes sure that we always ask for FI_CONTEXT
to eliminate any potential error.

OMPIO now uses the correct delete function depending on the fs
mca_common_ompio_file_delete now works this way instead
of calling POSIX unlink:
- create a minimal file handle with the given file name
- select the best fs component using this file handle
- call the component-specific file delete function

It is needed because the fs components might be queried due to a MPI_File_delete call.
And in this case, we don't have a communicator value.

instead of invoking ompi_request_test_all(), that will end up
calling opal_progress() recursively, manually check the status
of the requests.
the same method is used in ompi_comm_request_progress()

This commit fixes two bugs in the RMA/atomic emulation code:
1) Fix a fragment leak when using AMO emulation.
2) Always initialize the single-copy emulation code. This is required
to use the AMO support.

This commit fixes a crash that occurs when using btl/vader as an RDMA
btl. This btl supports using CPU atomics and does not support using
the btl for self communication so we must use the local memory
optimizations in osc/rdma.
