Jack Christensen 302c74f214 Fix: do not silently ignore assign NULL to *string 
AssignTo can only assign NULL to a **string. Previous code tried to
assign nil to a *string, which did nothing. Correct behavior is to
detect this as an error.

Jack Christensen 5297846239 pgtype.JSON(B).Value now returns []byte 
Allows scanning jsonb column into *json.RawMessage.

fixes #409

Jack Christensen f6d37536c4 Detect erroneous JSON(B) encoding 
JSON(B) automatically marshals any value. Avoid marshalling values of
pgtype.JSON and pgtype.JSONB. The caller certainly meant to call on a
pointer.

See https://github.com/jackc/pgx/issues/350 for discussion.

Jack Christensen 932caef600 pgtype DecodeText and DecodeBinary do not copy 
They now take ownership of the src argument.

Needed to change Scan to make a copy of []byte arguments as lib/pq apparently
gives Scan a shared memory buffer.

Jack Christensen a8c350c77d Use pointer methods for all struct pgtypes 
Now no need to no whether certain interfaces are implemented by struct or
pointer to struct.

Jack Christensen 19c6689752 Add pgtype.Record and prerequisite restructuring 
Because reading a record type requires the decoder to be able to look up oid
to type mapping and types such as hstore have types that are not fixed between
different PostgreSQL servers it was necessary to restructure the pgtype system
so all encoders and decodes take a *ConnInfo that includes oid/name/type
information.
