Add polynomial interpolation and minimization.

1. polynomial_solver* -> polynomial*.
2. Added support for differentiating polynomials.
2. Added support for interpolating polynomials from function
   values and gradients.
3. Added support for minimizing polynomials by solving
   for the roots of their derivatives in an interval.
4. Added support for finding the minimum of a polynomial
   that interpolates function values and gradients in
   an interval.
