This commit adds the implementation of SELECT JSON clause
which returns rows in JSON format. Each returned row has a single
'[json]' column.

There's no benefit to using C include guards so switch to pragma once
everywhere for consistency.

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.
The class inherits from abstract base class selectable so there's methods that
we need to define.
