[SciPy-Dev] please review cython optimize zeros api

[Mark Alexander Mikofski]

Hi,

PR 8431 is ready for review, IMHO.
https://github.com/scipy/scipy/pull/8431

This PR adds a Cython API for root-finding of scalar functions in Optimize.
It exposes brentq, brenth, ridder, bisect, newton, secant, and halley with
3 different callback signatures, two which are safe with Cython `nogil`
which allows them to be called with Cython `prange`.

this PR is a follow on to #8357, and allows efficient looping from C of
large arrays with the same callback using any of the scalar-function root
finders.

I would appreciate your comments.

Best,
Mark
