In #2081 we introduced a `coefficients` method for univariate polynomials
and power series, which only returns the nonzero coefficients.
{{{
sage: R.<x> = QQ[]
sage: (x^2+1).coefficients()
[1, 1]
}}}
* The result for `x^2 + 1` should be `[1, 0, 1]`.
* We should add a method `coefficients_nonzero` for univariate and
multivariable polynomials and power series that does what `coefficients`
now does.
* We should deprecate the `coefficients` method on multivariate
polynomials.
