BUG#11766427, BUG#59539: Filter by server id in mysqlbinlog fails

Browse Source 
Problem: mysqlbinlog --server-id may filter out Format_description_log_events.
If mysqlbinlog does not process the Format_description_log_event,
then mysqlbinlog cannot read the rest of the binary log correctly.
This can have the effect that mysqlbinlog crashes, generates an error,
or generates output that causes mysqld to crash, generate an error,
or corrupt data.
Fix: Never filter out Format_description_log_events. Also, never filter
out Rotate_log_events.


client/mysqlbinlog.cc:
  Process Format_description_log_events even when the
  server_id does not match the number given by --server-id.
mysql-test/t/mysqlbinlog.test:
  Add test case.
