  ENH: Add companion matrix functions.

The new companion matrices are related to the old by a
similarity transformation that makes them better conditioned
for root finding. In particular, the companion matrices for
the orthogonal polynomials are symmetric when the zeros of a
single polynomial term is wanted. This produces better zeros
for use in Gauss quadrature.

  BUG: The polynomial convenience classes let different types interact.

In particular for arithmetic where one could end up with a Polynomial
type with Chebyshev coefficients after an addition. It is unlikely that
that would be done on purpose.

The PolyDomain error message was also replaced by a TypeError with
an appropriate message. That seems like a better choice.

  ENH: Improve the computation of polynomials from roots.

The original method was overly sensitive to roundoff. Of the two
approaches considered, gauss integration or binary subdivision of
the roots, the latter is more compatible with using other number
representations such as mpmath. No method is going to be suitable
for large numbers of arbitrary zeros but the current method is a
significant improvement.
