Improve simple protocol / text format
...
Increased data type support for simple protocol. Improved test
coverage of simple protocol. This has the additional advantage of
exercising the text encoders and decoders.

Add RegisterDefaultPgType
...
This allows registering a mapping of a Go type to a PostgreSQL type
name. If the OID of a value to be encoded or decoded is unknown, this
additional mapping will be used to determine a suitable data type.

Clean up old Go 1.10 build tags

pgx requires Go modules which requires at least Go 1.11 so there is no
use in build tags to support older Go versions.

Improve stdlib performance with large result sets

In a hot path type assertions are expensive. Cache the already correctly
typed interfaces. ~20% improvement with 1000 rows.

Refactor Scan optimization
...
Instead of hardcoding specific types and skipping type assertions based
on that, only check if a destination is a (sql.Scanner) after a failed
AssignTo.
This is slightly slower in the non-decoder case and *very* slightly
faster in the decoder. However, this approach is cleaner and has the
potential for further optimizations.

Clarify Value.Get() documentation

Specifying behavior for Status Null and Undefined is incorrect because
a Value is not required to have a Status. In addition, standard
behavior is to return nil, not pgtype.Null when the Status is
pgtype.Null.

Remove pgtype.Row(), introduce Composite.Scan()
...
pgtype.Row() was optimized for a single line use
without much ceremony at a cost of OID registration,
which is cumbersome. In practice it so much incovnenience
to create new Composite just before making a query.
So now there is just a Composite type and 2 helper methods:
- SetFields sets composite fields to values passed. This assignment
fails if types passed are not assignable to Values pgtype is
made of.
- Scan acts exactly like query.Scan, but for a composite value. Passed
values are set to values from SQL composite.
