Replace debian_*() parser functions with facts

* Removes dependency on lsb-release and/or Facter >1.7
    (values are based on $::lsbdistcodename, when available)
* Simplifies maintenance: only lib/facter/util/* require updates as new
  releases are made

Caveats:
* apt::codename is removed; to override debian_* facts, set the
  FACTER_debian_codename environment variable for puppet
* If tracking unstable, make sure lsb-release is installed, as other
  methods can't tell between testing and unstable
