The Autoconf AC_CONFIG_* macros can only be instantiated exacly once
for any given file, *and* they must be in a code execution path at run
time for the target file to be generated at the end of configure.
For example, if you want to generate file ABC at the end of configure,
you must invoke the AC_CONFIG_FILES(ABC) macro in a code path that
will get executed when configure is run.
That's pretty straightforward.
What's not straightforward is two corner cases:
1. You cannot invoke the AC_CONFIG_FILES(ABC) macro for the same file
more than once. If you do, autoreconf will fail (even before you
can run configure).
2. If AC_CONFIG_FILES(ABC) is not in a code path that is executed by
configure, the file ABC is not registered properly, and ABC will
not be generated at the end of configure.
This applies to hwloc because hwloc's HWLOC_SETUP_CORE macro calls
both AC_CONFIG_FILES and AC_CONFIG_HEADER to setup its Makefiles
(etc.) so that targets like "make distclean" and "make distcheck" will
work properly. Hence, we *have* to invoke HWLOC_SETUP_CORE.
However, the MCA_opal_hwloc_hwloc201_CONFIG macro has a few side
effects. It would be nice to do able to do something like this:
```
if hwloc:extern is going to be used:
Invoke minimal HWLOC_SETUP_CORE (with no side effects)
else
Invoke full HWLOC_SETUP_CORE (with side effects)
fi
```
But we can't, because autoreconf will detect that AC_CONFIG_FILES has
been invoked on the same files more than once (regardless of whether
those code paths will be executed at run time or not). Kaboom.
Similarly, we can't do this:
```
if hwloc:extern is not going to be used:
Invoke full HWLOC_SETUP_CORE (with side effects)
fi
```
Because then hwloc's AC_CONFIG_FILES won't be registered properly when
hwloc:external *is* used (i.e., when the HWLOC_SETUP_CORE macro is not
in a code path that is executed at run time), and targets like "make
distclean" will fail because hwloc's Makefiles won't have been setup.
Kaboom.
But remember that the hwloc framework is a bit special: there will
only ever be 2 comoponents: external and internal. External is
guaranteed to be configured first because of its priority. So the
internal component (i.e., this component) immediately knows if it is
going to be used or not based on whether the external component
configuration succeeded or failed.
Specifically: regardless of whether the internal component (i.e., this
component) is going to be used, we have to invoke HWLOC_SETUP_CORE.
But we can manage the side effects: allow the side effects when
this/internal component is going to be used, and avoid the side
effects when this/internal component is not going to be used.
This is a little less clean than I would have liked, but because of
Autoconf's oddity about its AC_CONFIG_* macros, this is the only
solution I could come up with.

In order to make "make distclean" (and friends) work, we need to
*always* invoke the embedded configure script -- even if we know that
we're not going to use this component.
But in cases where we know we're not going to use this component, we
also need to avoid the side effects of the code path that is used when
we *do* want to use this component. So split the two possibilities
into two different macros:
1. MCA_opal_event_libevent2022_FAKE_CONFIG: which does almost nothing
except invoke the underlying "configure" script.
2. MCA_opal_event_libevent2022_REAL_CONFIG: which does all the real
work (including invoking the underlying "configure" script).

We know that event:external will be configured first (because of its
priority). Take advantage of that here in libevent2022 by having it
refuse to configure / politely fail if event:external succeeded.
Also print out some additional lines in configure output indicating
what is going on (i.e., event:external succeeded, so this component
will be skipped, or event:external failed, so this component will be
used).

Things got a little out of whack and we weren't actually processing the map-by modifiers, plus an error crept into the display of the binding report. So clean those up.

Per https://github.com/open-mpi/ompi/issues/5031, if the user didn't specify a particular PMIx installation, then default back to the internal version if it is newer than the discovered external one. PMIx doesn't yet provide a full signature so we have to just get as close as possible for now.

If OMPI is configured with `--with-hwloc=external` or `--with-hwloc=DIR`
and gfortran is used, I see a lot of warnings when compiling files
under the `ompi/mpi/fortran` directory.
```
f951: Warning: Nonexistent include directory
'BUILD_DIR/opal/mca/hwloc/external/hwloc/include' [-Wmissing-include-dirs]
```
There is no such `include` directory in the source tree and `configure`-
created tree. I think these lines in the `configure.m4` file are wrongly
copied from that for the embedded `hwlocXXX` component in the past.
The `-Wmissing-include-dirs` option is enabled in gfortran by default
but it is not enabled by default (or even with `-Wall`) in gcc and g++.

Fix two facepalms:
1. The "uint32" in the hash map functions refer to the *key* size, not
the *value* size. The values are always 64 bits.
2. Pass the straight value to the "set" functions -- not the pointer
to the value.
