bug#16093: 24.3.50; Crash of emacs --daemon on killing X server

[Nix]

Start emacs --daemon (using the lucid toolkit), under X. Shut X down.
Emacs crashes shortly afterwards.


The lack of symbol table info is concerning (obviously my gdb has
forgotten how to look up separated debug info *yet again*), but I don't
think that important, since the death site is after a (garbage-collect)
thus not in Lisp-land anyway. Obviously no xbacktrace is possible: the
process is dead.

It is fairly clear that we should not be calling xftfont_close() if the
X server is not there! Why has this started happening?
