ompi_mtl_portals4_get_endpoint() was incorrectly making a direct
call to ompi_mtl_portals4_add_procs(). Instead use the actve PML
to call add_procs(). If add_procs() fails, call ompi_rte_abort()
to terminate the job.

This option is problematic, and has never worked in an Open MPI v4.0.x
release tarball. Given that PMIx is now available elsewhere, it isn't
worth fixing this option.
See https://github.com/open-mpi/ompi/issues/6228 for more detail.
NOTE: This is a v4.0.x-specific commit because this option no longer
exists on master because we deleted the entire pmix3x component.
Hence, it's not possible to cherry-pick anything from master back to
the v4.0.x branch.

An implementation of R. Rabenseifner's algorithm for MPI_Iallreduce.
This algorithm is a combination of a reduce-scatter implemented with recursive vector halving
and recursive distance doubling, followed either by an allgather.
Limitations:
-- count >= 2^{\floor{\log_2 p}}
-- commutative operations only
-- intra-communicators only

Implements recursive doubling algorithm for MPI_Iexscan.
The algorithm preserves order of operations so it can be used both
by commutative and non-commutative operations.
The MCA parameter 'coll_libnbc_iexscan_algorithm' was added for dynamic

The call of MPI_Allgatherv with sendbuf and sendtype parameters equal to MPI_IN_PLACE and NULL correspondingly, produces the segmentation fault.
The problem is that sendtype is used even when sendbuf value is MPI_IN_PLACE. But according to the standard, sendtype and sendcount parameters should be ignored in this case.
