Remove XEmacs compatibility in Tramp

* doc/misc/tramp.texi: Replace flags by their hard coded name.
Remove unused flags and the enclosed alternative text for XEmacs.

* doc/misc/trampver.texi: Use "Tramp" CamelCase.  Rename "emacs"
and "xemacs" flags to "unified" and "separate".  Remove flags
"emacsgw", "emacsname", "emacsdir", "ftppackagename",
"emacsothername", "emacsotherdir" and "emacsotherfilename".
