This patch replaces the custom where clause processing by adding and
using a statement_restrictions field to modification_statement.
This improves code reuse and also moves some checks to prepare-time.

- Add a inserts, updates, deletes members to cql_stats.
- Store cql_stats& in a modification_statement and increment the corresponding counter according to the value of a "type" field.
- Store cql_stats& in a batch_statement and increment the statistics for each BATCH member.

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.
It's compared with size_t and is set from size_t. To avoid ugly casts
we can store it as unsigned int. It's always positive anyway. Origin
uses signed int ("int") because there is no unsigned int in Java.
