5f0d5f4255 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.

3ce29f9e05 Add Composite type for inplace row() values handling 
Composite() function returns a private type, which should
be registered with ConnInfo.RegisterDataType for the composite
type's OID.

All subsequent interaction with Composite types is to be done
via Row(...) function. Function return value can be either
passed as a query argument to build SQL composite value out of
individual fields or passed to Scan to read SQL composite value
back.

When passed to Scan, Row() should have first argument of type
*bool to flag NULL values returned from query.

ff95f82f70 Add ScanRowValue helper function 
ScanRowValue is useful when reading ROW() values with
known field types as well as composite types. It accepts
pgtype.Value arguments, where ROW() fields are written to
on successfull scan.

be9ceaefe6 Add native Go slice support for strings and numbers to simple protocol 
[]string, []int16, []int32, []int64, []int, []uint16, []uint32,
[]uint64, []uint, []float32, and []float64 are now supported in the
simple protocol like they are in the normal usage of the extended
protocol.
