- Fix some shortcomings in the xdmcp implementation. It used to
suppress loopback addresses from the list of potential display
addresses to report to xdm, even when talking to xdm through
a loopback address. Now only display addresses of the same kind
as the xdm connection are reported to xdm.
This most notably helps Xvnc servers contacting the local xdm,
because they were severely affected by the suppression of
loopback addresses.
