do not test that version string. So replication from 5.1.1-alpha
with the other event id's to a new version does not work.

allows us to simplify the big list above to the following regexes:
5\.1\.[1-5]-a_drop5.*

describes the other events' header/postheader lengths. This event is sent by
MySQL 5.0 whenever it starts sending a new binlog if the requested position
is >4 (otherwise if ==4 the event will be sent naturally).
