* net/tramp.el: Version 2.0.15 released.

(require 'base64): Most modern Emacsen have the base64
encode/decode functions built in, so test to see if they are bound
before we go blindly requiring base64.el.  From Steve Youngs
<youngs@xemacs.org>.
(tramp-feature-write-region-fix): XEmacs doesn't have a
'find-operation-coding-system' and this variable doesn't seem to
be used anywhere so wrap it in (unless (featurep 'xemacs)).  From
Steve Youngs <youngs@xemacs.org>.
(tramp-methods): Remove duplicate definition of ssh1-old and
ssh2-old.
(tramp-open-connection-su): Use user name "root" if no user name
is given.

From Michael Albinus <Michael.Albinus@alcatel.de>:
* net/tramp.el (tramp-invoke-ange-ftp):
(tramp-ange-ftp-file-name-p): Check for Xemacs.
(tramp-do-copy-or-rename-file): Don't pass KEEP-DATE to
tramp-invoke-ange-ftp 'rename.
(tramp-handle-write-region): Don't pass LOCKNAME and CONFIRM to
tramp-invoke-ange-ftp 'write-region.
(tramp-handle-set-file-modes): Change order of FILENAME and MODE
passing to tramp-invoke-ange-ftp 'set-file-modes.
(tramp-invoke-ange-ftp): `tramp-disable-ange-ftp' must be called
again after activating `ange-ftp'.
