[PATCH RFC xserver] dri3: Refuse to work for remote clients

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

Unfortunately, this doesn't help for DRI3 clients hanging waiting for the
reply from the DRI3Open request with display connections forwarded via
SSH (see https://bugs.freedesktop.org/show_bug.cgi?id=93261), because the
SSH proxy client appears local to the X server. This is an attempt to
gather ideas for how that problem should be addressed.
