Added support for all (?) events

- All (MariaDB and MySQL) events are now supported
- Added new api functions:
  - mariadb_rpl_error: returns error message
  - mariadb_rpl_errno: returns error number
  - mariadb_rpl_extract_rows: extract values of
    ROW_EVENTS
- Added decryption support
- Added uncompression
  -
