Detailed Description

Logs xid of the transaction-to-be-committed in the 2pc protocol. Has no meaning in replication, slaves ignore it.

Xid_log_event::Xid_log_event	(	const char *	buf,
		const Format_description_log_event *	description_event
	)

Note: It's ok not to use int8store here, as long as xid_t::set(ulonglong) and xid_t::get_my_xid doesn't do it either. We don't care about actual values of xids as long as identical numbers compare identically
