* lisp/find-file.el: Make the commands oblivious to mouse/non-mouse

(ff-find-other-file): Add `event` argument.
(ff-find-other-file-other-window): Rename from
`ff-mouse-find-other-file-other-window` and use this new argument.
(ff-mouse-find-other-file, ff-mouse-find-other-file-other-window):
Make them obsolete aliases.
(ff-upcase-p): Remove unused `start` and `end` arguments and
simplify accordingly.
