Description
Given a polynomial f and an indet x, produce a vector of the coeffs of f when viewed as a poly in x. The resulting vector v must satisfy f = \sum_i v[i]*x^i and each entry v[i] is of degree 0 in x.
The zero polynomial will produce an empty vector.
If f is multivariate the vector entries must be in RingOf(f).
If f is univariate the vector entries could be in CoeffRing(RingOf(f)) -- but this would be incompatible with the multivariate version. Perhaps the fns should have different names?

This has already been done: it is the function CoeffVecWRT.
