Kristian Nielsen 65353e1a40 Binlog-in-engine: mariabackup and concurrent FLUSH, PRUGE, or RESET MASTER 
The mariabackup copies innodb-implemented binlog files at the end of the
backup. This does not need to block any writes to the binlogs, as the
--prepare will use the InnoDB redo to recover them into a consistent state.

However, the copy might complain about a file missing if PURGE BINARY
LOGS or RESET MASTER is run in parallel; or about a file changing size
if FLUSH BINARY LOGS is run in parallel. So prevent that by taking a
low-impact BACKUP STAGE START lock during the binlog copy, and
blocking on that in PURGE, RESET MASTER and FLUSH BINARY LOGS.
