Adapt browse-url.el to improvements in Cygwin's cygstart utility.

* lisp/net/browse-url.el (browse-url-file-url): Remove Cygwin hack;
this is no longer needed now that cygstart understands file://
URLs.
(browse-url-filename-alist): For the same reason, don't modify
file:// URLs on Cygwin.
Encoding fix for browse-url-encode-url.

* lisp/net/browse-url.el (browse-url-url-encode-chars): Use upper-case.
(browse-url-encode-url): Encode spaces and quotes.
More CL cleanups and reduction of use of cl.el.
