MDEV-20119: Implement the --do-domain-ids, --ignore-domain-ids, and --ignore-server-ids options for mysqlbinlog

Browse Source 
New Feature:
============
Extend mariadb-binlog command-line tool to allow for filtering
events using GTID domain and server ids. The functionality mimics
that of a replica server’s DO_DOMAIN_IDS, IGNORE_DOMAIN_IDS, and
IGNORE_SERVER_IDS from CHANGE MASTER TO. For completeness, this
patch additionally adds the option --do-server-ids as an alias for
--server-id, which now accepts a list of server ids instead of a
single one.

Example usage:
  mariadb-binlog --do-domain-ids=2,3,4 --do-server-ids=1,3
  master-bin.000001

Functional Notes:
 1. --do-domain-ids cannot be combined with --ignore-domain-ids
 2. --do-server-ids cannot be combined with --ignore-server-ids
 3. A domain id filter can be combined with a server id filter
 4. When any new filter options are combined with the
--gtid-strict-mode option, events from excluded domains/servers are
not validated.
 5. Domain/server id filters can be combined with GTID ranges (i.e.
specifications of --start-position and --stop-position). However,
because the --stop-position option implicitly undertakes filtering
to only output events within its range of domains, when combined
with --do-domain-ids or --ignore-domain-ids, output will consist of
the intersection between the filters. Specifically, with
--do-domain-ids and --stop-position, only events with domain ids
present in both argument lists will be output. Conversely, with
--ignore-domain-ids and --stop-position, only events with domain ids
present in the --stop-position and absent from the
--ignore-domain-ids options will be output.
