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.
