Small fixes prompted by make check-declare

* lisp/frame.el (x-focus-frame): Update declaration.
(ns-mouse-absolute-pixel-position): Fix declaration.
* lisp/vc/diff-mode.el (diff-refine-hunk):
Use smerge-refine-regions rather than obsolete alias.
(smerge-refine-subst): Remove declaration, no longer relevant.
