1.) client/mysqlbinlog.cc - MariaDB has enhanced functionality for "process_event"
around "use db" statements.
2.) include/my_sys.h  - Since we are not patching the above we don't need "my_fprintf".
3.) mysql-test/r/mysqlbinlog-innodb.result - This test captures the above functionality.
4.) mysql-test/r/mysqlbinlog.result - not at all clear about #7 and #8 but looks like a should or can ignore.

5.) mysql-test/suite/binlog/r/binlog_base64_flag.result - I think this applied cleanly.

11.) sql/log_event.cc - This one is a right mess with methods getting mangled up.
Annotate_rows_log_event::pack_info apparently not present in oracle version
Had to copy User_var_log_event::pack_info over from MariaDB source.
