drop Xwayland
...
It always had it's own lifecycle (not been part of Xorg releases),
doesn't make sense to maintain a competing implementation that we
won't use anyways.
Once that's gone, we can also drop few things in core/dix that had
been added just for xwayland only.

xfree86: compat: re-export MarkClientException() for horryibly maintained Nvidia
...
NVidia yet again doing crazy shit in their proprietary drivers:
This is an DIX-*internal* function for triggering client teardown when
connection broke or somehow lack of resources to accept new connections.
Video drivers have no business with that whatsoever - having them messing
with client client connections is just insane.
But still trying to be kind with Nvidia victims, thus adding a little wrapper
function under the old name. It spills out a log warning calling users to file
bug reports their driver vendor.
