Remove Xau support.

After looking through this, I don't see any other way that Xauth
support is providing functionality other than to remote displays,
which exclude ssh X forwarding. Remote displays are in the form
where DISPLAY=some-other-machine:0.

We really don't care for those at all at this time, so let's
remove all this legacy support that we don't need as it just
complicates things.
