#6551: fix ugliness in printing of multivariate polynomials

-------------------------+--------------------------------------------------
The printing (and latex-ing) of multivariate polynomials is sometimes
quite ugly, and inconsistent with the much prettier printing of univariate
polynomials. One gets things like the following (taken from doctests in
the Sage library):
{{{
(-6/5)*x^2*y^2 + (-3)*x*y^3 + 6/5*x^2*y + 11/12*x*y^2 + (-18)*y^2 +
(-3/4)*y
}}}
or even
{{{
sage: xgcd((b+g)*y^2, (a+g)*y+b)
((b^3 + (g)*b^2)/(a^2 + (2*g)*a + 3), 1, ((-b + (-g))/(a + (g)))*y + (b^2
+ (g)*b)/(a^2 + (2*g)*a + 3))
}}}
The attached patch fixes this, factors out common code for printing and
latex-ing, and makes printing consistent across various representations of
multivariate polynomials.
