With Open MPI 5.0, the decision was made to stop building
3rd-party packages, such as Libevent, HWLOC, PMIx, and PRRTE as
MCA components and instead 1) start relying on external libraries
whenever possible and 2) Open MPI builds the 3rd party
libraries (if needed) as independent libraries, rather than
linked into libopen-pal.
This patch moves the hwloc library bundled with Open MPI from a
MCA framework to a stand-alone library built outside of OPAL. Due
to the amount of code in the MCA base (and its assumptions about
being part of an MCA framework), the framework is left with no
active components. Any pre-installed version of HWLOC 1.6 or
newer is preferred over the internal version.

This patch moves libevent from an MCA framework to a stand-alone
library built outside of OPAL. A wrapper in opal/util is provided
to minimize the unnecessary changes in the rest of the code. When
using the internal Libevent, it will be installed as a stand-alone
libevent.a, instead of bundled in OPAL. Any pre-installed version
of Libevent at or after 2.0.21 is preferred over the internal
version.

This patch is the first step in that process, providing foundational
changes required for supporting 3rd-party packages, such as changes
to autogen.pl, the top-level Makefile.am, and introducing two
Autoconf macros to support running sub-configure scripts; one
supporting source in tarball form and the other supporting
source in a sub-tree.

At the end of "make install", a tool is run to search for common
symbols in the built artifacts, to work around issues on MacOS.
This tool requires an exclude list for symbols that must be
in the common section (such as in executables instead of libraries
and because Fortran).
This commit adds the ability to exclude certain directories from
the search, such as directories that are 3rd party packages or
only contain tests/executables, which will not run into problems
on MacOS.
To simplify that change, the file search in find_common_syms was
also rewritten to use the Perl-standard File::Find package instead
of calling the find executable. Theoretically, this should be
mildly faster, but is also significantly easier to modify.

- Add support for fallback to previous coll module on non-commutative operations (#30)
- Replace mutexes by atomic operations.
- Use the correct nbc request type (for both ibcast and ireduce)
* coll/base: document type casts in ompi_coll_base_retain_*
- add module-wide topology cache
- use standard instead of synchronous send and add mca parameter to control mode of initial send in ireduce/ibcast
- reduce number of memory allocations
- call the default request completion.
- Remove the requests from the Fortran lookup conversion tables before completing
and free it.

The Linux component was an attempt to hook calls by patching the dynamic
symbol table. It, unfortunately, does not work as it will always miss
calls made internally by glibc. For example, it might catch a user call
directly to munmap but will miss the chain free -> munmap. Since the
later is the common case we were trying to hook this made the component
unusable. This PR finally kills the component.

Convert the MPI_Status_f082f, MPI_Status_f082c, and MPI_Status_f2c man
pages to Markdown. Fix some typos and improve the text a bit along
the way.
Left the raw NROFF redirect pages MPI_Status_f2f08, MPI_Status_c2f08,
and MPI_Status_c2f files as they were -- they're 1-line redirects, and
it seems simpler to leave those (vs. duplicating the Markdown).

Only in C bindings:
- MPI_Status_c2f08()
- MPI_Status_f082c()
In all bindings but mpif.h
- MPI_Status_f082f()
- MPI_Status_f2f08()
and the PMPI_* related subroutines
As initially inteded by the MPI forum, the Fortran to/from Fortran 2008
conversion subtoutines are *not* implemented in the mpif.h bindings.

Reduce scatter block and reduce scatter algorithms were hitting
correctness issues for non commutative strided tests. We will revert to
the original default algorithms for those two collectives (basic linear
and non overlapping respectively) in the non commutative op case.

As it is possible to have multiple outstanding non-blocking collectives
provided by different collective modules, we need a consistent
mechanism to allow them to select unique tags for each instance of a
collective.

* piggybacking Bull functionalities
* coll/adapt: Fix naming conventions and C11 atomic use
This commit fixes some naming convention issues, such as function names
which should follow the naming ompi_coll_adapt instead of
mca_coll_adapt, reserved for component and module naming (cf. tuned
collective component);
It also fixes the use of _Atomic construct, which is only valid in C11.
OPAL constructs have already been adapted to that use, so use
opal_atomic_* types instead.
* coll/adapt: Remove unused component field in module
This commit removes an unneeded field referencing the component in the
module of adapt, as it is already available through the
mca_coll_adapt_component global variable.
