Add option to include 16 bit EDNS tags in upstream queries, for specified destination addresses. Max one tag per query, the most specific match is selected.

Tags are configured using the edns-client-tag: <IP netblock> <tag data> configuration option, which is allowed multiple times. Tag data is configured in decimal format.
