Move "emacsclient -t -n" handling from emacsclient.c to server.el.

Fix its buggy logic for the Windows case (regression from 23.4).

* lib-src/emacsclient.c (decode_options): Move -t -n corner case handling
into server.el.

* lisp/server.el (server-process-filter): Handle corner case where both
tty and nowait options are present.

Fixes: debbugs:11102
