Log Message:
Update mysql4-{client,server} to 4.1.9.

Functionality added or changed:

    * The Mac OS X 10.3 installation disk images now include a MySQL
Preference Pane for the Mac OS X Control Panel that enables the user
to start and stop the MySQL server via the GUI and activate and
deactivate the automatic MySQL server startup on bootup.
    * Seconds_Behind_Master will be NULL (which means ``unknown'')
if the slave SQL thread is not running, or if the slave I/O thread
is not running or not connected to master. It will be zero if the
SQL thread has caught up with the I/O thread. It no longer grows
indefinitely if the master is idle.
    * InnoDB: Do not acquire an internal InnoDB table lock in LOCK
TABLES if AUTOCOMMIT=1. This helps in porting old MyISAM applications
to InnoDB. InnoDB table locks in that case caused deadlocks very easily.
    * InnoDB: Print a more descriptive error and refuse to start InnoDB
if the size of `ibdata' files is smaller than what is stored in the
tablespace header; innodb_force_recovery overrides this.
    * The MySQL server aborts immediately instead of simply issuing a
warning if it is started with the --log-bin option but cannot
initialize the binary log at startup (that is, an error occurs when
writing to the binary log file or binary log index file).
    * The binary log file and binary log index file now behave like
MyISAM when there is a "disk full" or "quota exceeded" error. See
section A.4.3 How MySQL Handles a Full Disk.
