telephony: Add support for choosing a default APN

 * Sometimes, the standard method of choosing the "first" available APN
   is not what we want. Consider the case where a certain provider has
   both a "normal" APN and an LTE APN. The LTE APN is what we want, but
   it's not chosen.
 * Add a new overlayable value "config_preferred_apn" to handle this. A
   device can override this. The format is "apn,mcc,mnc".

Drop blacklist number uniqueness constraint.

It's very hard to deal with that constraint in practise, so drop the
contraint from the DB and handle potential duplicate rows when querying.
