Add Option "TearFree" v4
Avoids tearing by flipping between two scanout BOs per (non-rotated) CRTC
v2:
* Fix condition for TearFree log message (Richard Wilbur)
* Log warning message about DRI page flipping being enabled because of
TearFree (or ShadowPrimary) also when building without glamor support
v3:
* Only override fb_id/x/y if all scanout pixmaps have been successfully
allocated
v4:
* Make log warning clearer if drmModePageFlip returns an error
