Misc cleanups and simplifications.

* lisp/font-lock.el (save-buffer-state): Remove `varlist' arg.
(font-lock-unfontify-region, font-lock-default-fontify-region):
Update usage correspondingly.
(font-lock-fontify-syntactic-keywords-region):
Set parse-sexp-lookup-properties buffer-locally here.
(font-lock-fontify-syntactically-region): Remove unused `ppss' arg.
* lisp/progmodes/ada-mode.el: Replace "(set '" with setq.
(ada-mode): Simplify.
(ada-create-case-exception, ada-adjust-case-interactive)
(ada-adjust-case-region, ada-format-paramlist, ada-indent-current)
(ada-search-ignore-string-comment, ada-move-to-start)
(ada-move-to-end): Use with-syntax-table.
* lisp/progmodes/fortran.el (fortran-line-length): Don't recompute
syntactic keywords redundantly a second time.
* lisp/progmodes/js.el (require): Require is already "eval-and-compile".
(js--re-search-forward): Avoid `eval'.  Preserve the error data.
(js--re-search-backward): Use js--re-search-forward.
* lisp/progmodes/octave-mod.el (electric-indent-chars): Silence bytecomp.
