(tar-file-name-handler): New function.

(tar-extract): Bind file-name-handler-alist to it to force
find-buffer-file-type-coding-system behave as if the file being extracted
existed.  Use last-coding-system-used to force buffer-file-coding-system
to what decode-coding-region actually used to decode the file.
