got linked together (work on one caused work in the other):
* Clean up a bunch of VAR_SCOPE issues in configure. This includes:
* Using VAR_SCOPE_PUSH and VAR_SCOPE_POP in more places
* Cleaning up the use of some shell variables (e.g., name them better)
* Add support for external libevent via
--with-libevent=<dir-to-libevent-install-tree>, as specifically
asked for by downstream packagers.
* Revamp how wrapper compiler RPATH (and RUNPATH) support is done.
The external libevent work exposed weakenesses in how the original
RPATH/RUNPATH work was done, so we had to re-do it to be a bit more
robust.
This work has not yet been tested on Solaris.

This prevents bazillions of warnings from clang tha -Wno-long-double
isn't supported.
The warning that clang issues when it see -Wno-long-double is does not
use any of the words we were looking for, so I added "unknown" to the
list of words to look for. I also re-indented the two m4 tests so
that they're a bit more readable.

flags, and mca flags are kept seperate until the very end. The main configure
wrapper flags should now be modified by using the OPAL_WRAPPER_FLAGS_ADD
macro. MCA components should either let <framework>_<component>_{LIBS,LDFLAGS}
be copied over OR set <framework>_<component>_WRAPPER_EXTRA_{LIBS,LDFLAGS}.
The situations in which WRAPPER CPPFLAGS can be set by MCA components was
made very small to match the one use case where it makes sense.

config/ directory. We split them apart a while ago in the hopes that
it would simplify things, but it didn't really (e.g., because there
were still some ompi/opal .m4 files in the top-level config/
directory, resulting in developer confusion where any given m4 macro
was defined).
So this commit consolidates them back into the top-level directory for
simplicity.
There's still (at least) two changes that would be nice to make:
1. Split any generated .m4 file (e.g., autogen-generated .m4 files)
into a separate directory somewhere so that a top-level -Iconfig/
will only get our explicitly defined macros, not the autogen stuff
(e.g., with libevent2019 needing to get the visibility macro, but
NOT all the autogen-generated inclusion of component configure.m4
files).
1. Change configure to be of the form:
{{{
# ...a small amount of preamble/setup...
OPAL_SETUP
m4_ifdef([project_orte], [ORTE_SETUP])
m4_ifdef([project_ompi], [OMPI_SETUP])
# ...a small amount of finishing stuff...
}}}
I doubt we'll ever get anything as clean as that, but that would be
the goal to shoot for.
