    This changeset adds replication of events and user-defined functions. 
    There are several bug reports involved in this change:
    
    BUG#16421, BUG#17857, BUG#20384:
    This patch modifies the mysql.events table to permit the addition of
    another enum value for the status column. The column now has values
    of ('DISABLED','SLAVESIDE_DISABLED','ENABLED'). A status of
    SLAVESIDE_DISABLED is set on the slave during replication of events.
    This enables users to determine which events werereplicated from the 
    master and to later enable them if they promote the slave to a master.
    The CREATE, ALTER, and DROP statements are binlogged.
    A new test was added for replication of events (rpl_events).
    
    BUG#17671:
    This patch modifies the code to permit logging of user-defined functions.
    Note: this is the CREATE FUNCTION ... SONAME variety. A more friendly error 
    message to be displayed should a replicated user-defined function not be
    found in the loadable library or if the library is missing from the
    slave.The CREATE andDROP statements are binlogged. A new test was added 
    for replication of user-defined functions (rpl_udf). 
    
    The patch also adds a new column to the mysql.event table named
    'originator' that is used to store the server_id of the server that
    the event originated on. This enables users to promote a slave to a 
    master and later return the promoted slave to a slave and disable the
    replicated events.
