Pageflips for Pixmap presents were not synchronized to vblank on
drivers with support for PresentCapabilityAsync, due to some
missing init for vblank->sync_flips. The PresentOptionAsync
flag was completely ignored for pageflipped presents.
Vsynced flips only worked by accident on the intel-ddx, as that
driver doesn't have PresentCapabilityAsync support.
On nouveau-ddx, which supports PresentCapabilityAsync, this
always caused non-vsynced pageflips with pretty ugly tearing.
This patch fixes the problem, as tested on top of XOrg 1.16.2
on nouveau and intel.
v4: Add additional PresentCapabilityAsync caps check, as
suggested by Eric Anholt.
Please also apply to XOrg 1.17 and XOrg 1.16.2 stable.
Applying on top of XOrg 1.16.2 requires cherry-picking
