Updated compatibility for rewriting equality proofs that are dependent
- made the new "subst'" the default by renaming it "subst";
- renamed old "subst" into "simple subst";
- add option for non-rewriting of dependent proofs in general_rewrite and co
- kept use of dependent proofs in the "subst" call of "functional
induction", in spite it introduced incompatibilities (in Compcert).
