implement SQLSTATE style error codes.

Allow drivers to add methods to dbh and stmt objects
(note that we can't use a class, because the use only sees the PDO class).
Clarify the api slightly:
  PDO::exec() is used for one-shot queries that don't return rows
  PDO::query() is a convenience function for returning a rowset without
  having to go through the steps of preparing and executing.
