Be more careful than just exporting CPPFLAGS (or not) to sub-
configure scripts. This fixes a bug in which --enable-visibility
would cause PRRTE's configure to fail, because the top-level
configure added -Wmissing-prototypes to CPPFLAGS and then
the subconfigure added -Werror at one point. In general,
blindly exporting all the CPPFLAGS OMPI adds was a bad idea, so
we instead only export precious variables if they were
set in the calling environment, on the command line of the
top-level configure, or explicitly added to the sub-
configure environment (like CPPFLAGS for PMIx/PRRTE).
Add some envirnoment scrubbing/saving/restore wrappers and
modify PAC_CONFIG_SUBDIR_ARGS to play a little nicer with
precious variables so that this all works.

The ignore argument to PAC_CONFIG_SUBDIR_ARGS is an m4 list of
sed expressions. --with-platform=.* ignored not just the platform
argument, but everything after it. Fix the regular expressions to
ignore everything until the next whitespace. This probably still
isn't entirely right, because it will fail if the argument has
spaces in it (like a path with spaces), but we fail that test
so many other places that it does not add to the fail.

In reworking the 3rd-party package support for Libevent and HWLOC,
it appears that we missed exporting the opal_<package>_CPPFLAGS
variable (despite documentation). Fix that shortcoming.

The refactoring patches move Libevent from a framework integration
to a 3rd-party package, but did not change the Libevent version
that Open MPI ships. During that swap, we stopped running the
Autotools on Libevent and relied on the tools the Libevent authors
used when building the 2.0.22 release tarball. The config.guess
in this release tarball did not work on the IBM systems.
This patch updates the release version of Libevent to 2.1.12-stable,
which will suck in a bunch of upstream bug fixes and updates
the config.guess so that the 3rd-party refactoring actually
compiles on the IBM Power systems.

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 prrte submodule from the top-level to the
3rd-party directory, to match the behavior of other 3rd-party
packages like Libevent and PMIx. Since Open MPI does not
support building with an external PRRTE, that functionality
is skipped in this patch.

This patch moves the PMIx 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 PMIx 3.0.0 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.

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).
