A whole new implemenation of the refine tactic.

It now uses the same algorithm as pretyping does.

This produces pretty weird goal when refining pattern matching terms.
Modification of the pattern matching compilation algorithm are pending, hence I will let it be so for now.

The file Zsqrt_compat.v has two temporary [Admitted] related to this issue.
