Changes 2.2.2:
* psycopg/cursor_type.c: executemany() propagates exceptions raised by the
  iterable to the caller.
* lib/pool.py: dropped logging.basicConfig() call.  It messes up with
  projects using logging but where no handler is installed on the root
  logger.
* psycopg/cursor_type.c: exceptions raised in the columns iterator of the
  copy methods propagated to the caller.
* psycopg/typecast_datetime.c: Round seconds in historical timezones to
  the nearest minute.
* lib/extras.py: register_tstz_w_secs() is now no-op.

Changes 2.2.1:
* Builds again on Windows.
