Reorganize and flesh out the code to get the tiering configuration.

This moves all those routines into aptitude_universe, because the code
that will want to use them doesn't touch the resolver directly (only
its output).  Also implemented an (untested) routine to translate
tiers into names in a configurable manner, and created a new logging
domain for setting up initial tiers.
