Note that "backend Cyrus in MySQL" is not at all the same thing as "have a
cyrusdb backend that supports mysql"

The former just isn't really feasable.  However the later is feasable, it
just isn't efficient for mailboxes and seen state.  It might be reasonable
for deliver.db (with the exception that expiration is likely to be slow),
and if the database was local it might be useful for tls sessions (same
problem with expiration).

As it turns out, with the CVS additions that allow quota to be backended
by cyrusdb, there is actually a situation where backending the quota
database in mysql is a win -- that is, being able to have a quota root
that is split between murder backends (still only likely to be useful for
shared folders).
