dix: Pass ClientPtr to FlushCallback
Backported X.org commits: commit b380f3ac51f40ffefcde7d3db5c4c149f274246d Author: Michel Dänzer <michel.daenzer@amd.com> Date: Tue Aug 2 17:53:01 2016 +0900 dix: Pass ClientPtr to FlushCallback This change has two effects: 1. Only calls FlushCallbacks when we're actually flushing data to a client. The unnecessary FlushCallback calls could cause significant performance degradation with compositing, which is significantly reduced even without any driver changes. 2. By passing the ClientPtr to FlushCallbacks, drivers can completely eliminate unnecessary flushing of GPU commands by keeping track of whether we're flushing any XDamageNotify events to the client for which the corresponding rendering commands haven't been flushed to the GPU yet.

Drivers may use the flush callback to submit batched up rendering before events (for example, damage events) are sent out, to ensure that the rendering has been queued when the client receives the event.
