Split the sentinel library in ompi/mpi/fortran/use-mpi-f08 into
- the real sentinel that contains no code (only used to build the .mod files)
- an internal library that does contain some code
and have libmpi_usempif08.la slurp the latter.
This fixes a regression introduced in open-mpi/ompi@5de5e751ed

This commit fixes issue #6853 by removing
MacOS/Darwin-specific logic from intercept_mmap.
It also opportunistically converts tabs to spaces.

Due to IF_NAMESIZE being a reused and conditionally defined macro,
issues could arise from macro mismatches. In particular, in cases where
opal/util/if.h is included, but net/if.h is not, IF_NAMESIZE will be 32.
If net/if.h is included on Linux systems, IF_NAMESIZE will be 16. This
can cause a mismatch when using the same macro on a system. Thus
different parts of the code can have differring ideas on the size of a
structure containing a char name[IF_NAMESIZE]. To avoid this error case,
we avoid reusing the IF_NAMESIZE macro and instead define our own as
OPAL_IF_NAMESIZE.

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.

After the OPAL_MODEX_RECV call, remote_addrs was not freed in the error
path. Moved the free call into cleanup to ensure we always free this
memory before leaving the function.

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

The parameter names were misleading due to implying a single interface
instead of a list. This will provide more clarity in distinguishing the
list of interfaces from each individual interface.

Start optimizing the code.
This commit divides the operations in 2 parts, the first, outside the
critical part, deals with partial blocks of predefined elements, and the
second, inside the critical path, only deals with full blocks of
elements. This reduces the number of expensive operations in the
critical path and results in a decent performance increase.

Amazing how a bad instruction scheduling can have such a drastic impact
on the code performance. With this change, the get a boost of at least
50% on the performance of data with a small blocklen and/or count.

Optimize contiguous loops by collapsing them into a single element.
During datatype optimization collapse similar elements into larger
blocks.
