We were missing calls to underlying_type in a few locations and so the
insert would think the given literal was invalid and the select would
refuse to fetch a UDT field.

Both cql3_type and abstract_type are normally used inside
shared_ptr. This creates a problem when an abstract_type needs to refer
to a cql3_type as that creates a cycle.
To avoid warnings from asan, we were using a std::unordered_map to
store one of the edges of the cycle. This avoids the warning, but
wastes even more memory.
Even before this patch cql3_type was a fairly light weight
structure. This patch pushes in that direction and now cql3_type is a
struct with a single member variable, a data_type.
This avoids the reference cycle and is easier to understand IMHO.

Virtual columns should not be visible to the user,
so they are now hidden not only from directly selecting them,
but also via WRITETIME() and TTL() keywords.
Fixes#4288
sprint() recently became more strict, throwing on sprint("%s", 5). Replace
with the more modern format().
Mechanically converted with https://github.com/avikivity/unsprint.
writetime() or ttl() selections of non-frozen collections can work, as they
are single cells. Relax the check to allow them, and only forbid non-frozen
collections.
Fixes#3825.
Tests: cql_query_test (release).

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

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.
