build: replace autotools with cmake

this patch removes all the autoconf/automake/libtool build
infrastructure and replaces it with cmake.

notable default behavior changes:
- man pages are not pre-built, and are not built by default, must be
  enabled with `-DBUILD_MANPAGES=ON`.

removed features:
- srpm packaging, to be reintroduced at some point.
- deb packaging, now handled externally via rafaelmartins/deb.rgm.io

more stuff must be missing, please report bugs!
