automake: add basic framwork

* Added needed boilerplate to configure.ac

* Wrap original Makefile's with automake:
  - Renamed all original Makefile -> Makefile.legacy
  - Force automake generated Makefile to call Makefile.legacy:
    Currently handle: all, install, clean, distclean, dist, docs, config
  - Note: our temporary 'dist' target conflicts with automake 'dist' target.

* Temporarily added extra dist files into build_tools/make_dist
  (until we move "make dist" functionality into automake)

* For now, we don't try to compile ppp/ as it wasn't compiled
  from the top-level Makefile before.
