From: Michel Dänzer <michel.daenzer@amd.com>
Should make the amdgpu_drm_queue_alloc error handling clearer, and gets
rid of a compile warning about it returning NULL.

We only need to flush for XDamageNotify events.
Significantly reduces compositing slowdown due to flushing overhead, in
particular with glamor.

This further reduces the compositing slowdown due to flushing overhead,
by only flushing when the X server actually sends XDamageNotify events
to a client, and there hasn't been a flush yet in the meantime.

At least with older kernels, the flip may never complete otherwise,
which can result in us hanging in drmmode_set_mode_major.

This should allow using multiple CRTCs via RandR 1.4 even with xserver
< 1.17. It also simplifies the code a little, and paves the way for
following changes.

From: Michel Dänzer <michel.daenzer@amd.com>
Only copy once for each time we update the corresponding scanout pixmap.
This can significantly reduce the bandwidth usage when there are
frequent updates to the screen pixmap.
This initial implementation only works when both the master and slave
screens use this driver.

From: Michel Dänzer <michel.daenzer@amd.com>
Copy the damaged areas which are still valid in the other scanout pixmap
from there, then only copy the remaining damaged area from the screen
pixmap.
This is slightly more efficient (only needs one Damage record instead of
two, and only needs to copy each screen update across PCIe once with
ShadowPrimary and a discrete GPU), and will be significantly more
efficient for PRIME with the following change.

To: amd-gfx-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW
From: Michel Dänzer <michel.daenzer@amd.com>
TearFree can now prevent tearing with any possible display
configuration.
Note that there may still be inter-GPU tearing if the primary GPU uses
a different driver.
