Description (last modified by saraedum)

sage.rings.polynomial.polynomial_element.Polynomial provides an implementation for _xgcd. This implementation is not correct for polynomials over arbitrary rings. Therefore it should be moved to sage.rings.polynomial.polynomial_element_generic.Polynomial_generic_field.

The way it currently is, doesn't cause any bugs because only elements of a PID call the _xgcd method.
