This patch augments Gtid_log_event with the user thread-id. In particular that compensates for the loss of this info in Rows_log_events. Gtid_log_event::thread_id gets visible in mysqlbinlog output like #231025 16:21:45 server id 1 end_log_pos 537 CRC32 0x1cf1d963 GTID 0-1-2 ddl thread_id=10 as a 32 bit unsigned integer. Note this is a 32-bit value, as the connection id can only be 32 bits (see MDEV-15089 for details). While the size of Gtid event has grown by 4 bytes replication from OLD <-> NEW is not affected by it. This patch also slightly changes the logic to convert Gtid events to Query events for older replicas which don't support Gtid. Instead of hard-coding the padding of the sys var section of the generated Query event, the length to pad is dynamically calculated based on the length of the Gtid event. This work was started by the late Sujatha Sivakumar. Brandon Nesterenko took it over, reviewed initial patches and extended the work. Also thanks to Andrei for his help in finalizing the fixes for MDEV-33924, which were squashed into this patch.

# id of the thread which originally executed the transaction. On the primary,

# this is the id of the user connection (or the pseudo_thread_id). The replica
