Enrico Weigelt, metux IT consult 473b8a0e38 dix: helper for checking whether window ID belongs to a root window ...

This helper checks whether a given XID belongs to some screen's
root window. It does so by looking up the window and comparing that
with the window's screen's root window pointer. The resource lookup
is intentionally being on behalf of the serverClient, so the fired
XACE hook doesn't treat it as an actual client's request.

It's explicitly designed for being used by callback handlers.
