To prepare a user-defined type, we need to look up its name in the keyspace. While we get the keyspace name as an argument to prepare(), it is useless without the database instance. Fix the problem by passing a database reference along with the keyspace. This precolates through the class structure, so most cql3 raw types end up receiving this treatment. Origin gets along without it by using a singleton. We can't do this due to sharding (we could use a thread-local instance, but that's ugly too). Hopefully the transition to a visitor will clean this up.
