This brings the log levels emitted by connmark pattern code in line with
the rest of the code base. LOG_DEBUG is used for diagnostics that may be
verbose depending on the request patterns. LOG_ERR is used for problems
with the implementation itself.

This extends query filtering support beyond what is currently possible
with the `--ipset` configuration option, by adding support for:
1) Specifying allowlists on a per-client basis, based on their
associated Linux connection track mark.
2) Dynamic configuration of allowlists via Ubus.
3) Reporting when a DNS query resolves or is rejected via Ubus.
4) DNS name patterns containing wildcards.
Disallowed queries are not forwarded; they are rejected
with a REFUSED error code.
