Partial rewrite of the sysdeps code:

* added support for reading multiple sysdeps files (so they can be split and thus the redundancy reduced)
* fallback to unstable distro version if current version is unknown (so it won't stop working when Fedora switches versions)
* abort if no sysdeps are available (since sugar-jhbuild will break in unexpected ways otherwise)
* cache distribution information and dependency list to speed up execution
