univariate homogenize is not the same as multivariate homogenize

[ncalexan]

Ticket #2349 fixes the multivariate case. This ticket is for the univariate case. Some examples (these work after like this AFTER #2349 has been applied):

sage: x = Zmod(3)['x'].0; (x^2 + x).homogenize()
---------------------------------------------------------------------------
<type 'exceptions.AttributeError'>        Traceback (most recent call last)

/Users/ncalexan/<ipython console> in <module>()

<type 'exceptions.AttributeError'>: 'sage.rings.polynomial.polynomial_modn_dense_ntl.Po' object has no attribute 'homogenize'
sage: x = PolynomialRing(Zmod(3), 1, 'x').0; (x^2 + x).homogenize()
x^2 + x*h
sage: x = GF(3)['x'].0; (x^2 + x).homogenize()

One step more to unify some methods of univariate and multivariate polynomials.
