These issues were introduced in the recent commit b71af0eca0.
This commit fixes Coverity CID 1451661 and 1451660.
Though `c_info` part was an actual bug, the `c_sendtypes` part was not.

Update PMIx to latest master to get supporting updates. For
connect/accept (part of comm_spawn as well), lookup locality for all
participating procs on the node and compute the relative locality so it
can be used for MPI operations.

Use linear with sync alltoall algorithm for certain message/comm size
ranges. Does not affect default fixed decision, unless HPCX (with its
custom parameters) is used or corresponding mca is set.

- ignore sendcounts, sendispls and sendtypes arguments when MPI_IN_PLACE is used
- use the right size when an inter-communicator is used.
Thanks Markus Geimer for reporting this.

A sentinel is only an internal Fortran module and hence should not
be slurped into libmpi_usempif08.so

MPI standard states a user MPI_Op and/or user MPI_Datatype can be free'd
after a call to a non blocking collective and before the non-blocking
collective completes.
Retain user (only) MPI_Op and MPI_Datatype when the non blocking call is
invoked, and set a request callback so they are free'd when the MPI_Request
completes.
Thanks Thomas Ponweiser for reporting this

Move toward a base type of vector (count, type, blocklen, extent, disp)
with disp and extent applying toward the count repertition and blocklen
being a contiguous memory of type type.
Implement 2 optimizations on this description used during type_commit:
- collapse: successive similar datatype descriptions are collapsed
together with an increased count.
- fusion: fuse successive datatype descriptions in order to minimize the
number of resulting memcpy during pack/unpack.
Fixes at the OMPI datatype level including:
- Fix the create_hindexed and vector creation.
- Fix the handling of [get|set]_elements and _count.
- Correctly compute the dispacement for block indexed types.
- Support the MPI_LB and MPI_UB deprecation, aka. OMPI_ENABLE_MPI1_COMPAT.

Since array_of_errcodes is only allocated when MPI_ERRCODES_IGNORE is not used,
it should not be cleaned when MPI_ERRCODES_IGNORE is used.
Correctly allocate array_of_errcodes with the right size (e.g. maxprocs).

To avoid fully initializing the osc/ucx component for MPI application
that are not using One-Sided functionality, the initialization happens
at the first MPI window creation.

In common_ompi_aggregators calc_cost routine:
do not cast the real division to an int intermediately.
This patch removes the obsolete int variable c and assigns
the result of the P_a/P_x division directly to n_as.
With the intermediate int c variable, n_as gets 0 if P_a < P_x,
resulting in a division by 0 when computing n_s.
