HEALPix, Autoconf and Automake now in library

The tarball of HEALPix includes multiple languages and doesn't include the
ready-to-run GNU Build System by default, we actually have to build the
`./configure' script for the C/C++ libraries. So it was necessary to also
include GNU Autoconf and GNU Automake as prerequisites of HEALPix.

However, the official GNU Autoconf tarball (dating from 2012) doesn't build
on modern systems, so I just cloned it from its source and bootstrapped it
and built its modern tarball which we are using here.
