Only default to the external component if its version is
greater or equal than the internal libevent (2.0.22)

- Always use the external component when configure'd with --with-libevent=external
- Fix the external libevent library version detection
by testing _EVENT_NUMERIC_VERSION and EVENT__NUMERIC_VERSION macros
- Use the event2/event.h header (event.h is deprecated since libevent 2.0

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.
