zero-size derived datatypes are now flagged as OPAL_DATATYPE_FLAG_CONTIGUOUS
so update mca_pml_ucx_init_datatype() to correctly handle them.
Since 'size' is a 'size_t', the assertion can simply be removed.

individual read/write operations exceeding 2GB fail in ompio
due to improper conversions from size_t to int in two different
locations. This commit fixes an issue reported by Richard Warren

one off patch for v4.0.x. for some reason commit on master
didn't have this problem.
Signed-off-by: Howard Pritchard <howardp@lanl.gov>
(cherry picked from commit 5f3dbdb5c8)
Note that this commit is actually a cherry-pick from the v4.0.x
branch. This is the opposite direction than what we nornmally do: we
usually commit to master first and then cherry-pick to the release
branches (vs. the other way around).
As is probably evident from the original commit message above, through
a comedy of errors, this commit was actually applied to the v4.0.x
branch first and then cherry-picked back to master (i.e., the problem
*did* exist in the original master commit
3aca4af548, but it was not recongized at
the time).

INTERNAL: STL-59403
The OFI (libfabric) MTL does not respect the maximum message size
parameter that OFI provides in the fi_info data.
This patch adds this missing max_msg_size field to the mca_ofi_module_t
structure and adds a length check to the low-level send routines.

I'm restoring the info function pointers to the IO module
but allowing the function pointers to be NULL (eg in ompio).
And letting romio321 set its function pointers for those
routines.
This means the info system uses the new OMPI-level info
system for most things, but skips it and uses the pre-existing
romio info system just for the romio module.
It's possible to convert romio, but I went a ways down that
path and found it kind of convoluted. Having pointers from
the lower level ADIO_File back to the higher level ompi_file_t
wasn't too bad, but I got stuck trying to figure out where/how
to register the infosubscribe_subscribe callbacks vs the way
initial k/v values are scattered around the romio code currently.

open-mpi/ompi@0fe756d416 Introduced
a bug in coll/hcoll component. The ompi_requests allocated by
libhcoll would be treated as coll_base_nbc_request during
ompi_coll_base_retain_<> call. Afterwards this would lead to a
segv in the request cleanup.
Fix: since libhcoll interface does not distinguish between the
blocling/non-blocking requests use coll_base_nbc_request all the
time and initialize it properly in
coll/hcoll/get_coll_handle(). It is still within 2 cache lines.

Within the shuffle iteration, the aggregators have to set a displacement array needed to receive data from other processes. The array had 1 extra element. We adjust the displacement index to match the number of elements.

a non blocking collective might return ompi_request_null, so we should not
retain anything in that case.

Since ompi_coll_base_nbc_request_t is to be used in an
opal_free_list_t, it must be returned into a "clean" state.
So cleanup some data in the callback completion subroutines.
