MDEV-19117 Don't keep binary log index file locked during show binary logs
On some systems with 10,000+ binlogs, show binary logs could block log rotation for more than 10 seconds. This patch fixes this by first caching all binary log names and releases all mutexes while calculating the sizes of the binary logs. Other things: - Ensure that reinit_io_cache() sets end_of_file when moving to read_cache. This ensures that external changes of the underlying file is known to the cache. - get_binlog_list() is made more efficent and show_binlogs() is changed to call get_binlog_list() Reviewed by Andrei Elkin
