This wrapped CloseScreen function doesn't do anything actually useful,
so no need to keep it around any longer. It used to do a free() on the
private data (which had been wrong in the first place) but this had
been removed and so the whole function became useless, it had been
forgotten to be swept away.

public server module API headers shouldn't be clobbered with non-exported
definitions, so move them out to private header file.
