There's no benefit to using C include guards so switch to pragma once

There's a cyclic dependency between cql3 and transport namespaces when
we introduce prepared statements. The latter pulls
parsed_statement::prepared from the former. Break the cycle by using
a forward delcaration in cql_statement.hh.

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.
The method may defer so the result is wrapped in future<>.
I think we don't need to wrap arguments in shared_ptr<> because they
may come from the request state object.
