Botond Dénes 6c3f104b67 cql3: store raw query string in utils::chunked_string 
Read query as fragmented string from the input stream in
transport/server.cc, propagate it a such to query_processor::prepare()
and also store it as such in cql3::cql_statement::raw_cql_statement.

Unfortunately, the query still has to be linearized for parsing, as
ANTLR -- although allows for custom InputStream implementation -- plays
pointer arithmetics games with the pointers obtained from them, so
fragmented input cannot be used.
To amortize the cost of this linearization, the query string is
linearized through utils::reusable_buffer. The parser can be
invoked recursively, nested invokations linearize directly.

Still, this patch limits the places where the query is linearized to the
following:
* Parsing
* Audit
* Logs and error messages

So the normal query paths for queries that actually can get arbitrarily
large (UPDATE and INSERT) should only linearize the query temporarily
for parsing.
