It looks like some of the newer libtool m4 files offer improved support
for the Darwin platform and possibly BSD, so bump our files to these new
versions.

* Greatly simplify and de-obfuscate the autogen and autoclean code.
* Add a bunch of the autotools required files to the repository. This
will give us consistency (a novel idea) across all builds, and allow
for much more recent versions of config.guess and config.sub to be used.
