Subject: [PATCH] Port Tramp manual to latest Texinfo

Otherwise, 'make pdf' did not work (Bug#22416).
* doc/misc/tramp.texi (xxx, yyy): Remove macros.
(trampfn): Specialize to the case where METHOD is nonempty.
The 2nd argument is now user@host, not 2nd user and 3rd host args.
All uses changed.
(trampf): New macro.
