[PATCH 4/4] randr: report changes when we disconnect a GPU slave

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

When we disconnect an output/offload slave set the changed bits,
so a later TellChanged can do something.

Then when we remove a GPU slave device, sent change notification
to the protocol screen.

This allows hot unplugged USB devices to disappear in clients.
