sna: Enable blitting with Y-tiled surfaces
I have not spotted whether it is a missing magic bit or a bad GTT path,
but ideally we don't want to switch to BLT along that path anyway (since
we are in the middle of rendering with the other engine).

Since the first flip may require a fixup, we will only really know with
the second flip whether we can start a flip chain with different tiling.

If we receive an error from the pageflip ioctl, we attempt to set the
framebuffer using SETCRTC instead. This is so that we can transition
between pitches and offsets for a CRTC. However, the kernel may reject a
flip also for tiling changes, or for any reason, which we also want to
transparently handle. Rearrange the error message and flip->blit
fallback handling to only do so if we try to flip twice (i.e. after
resetting the CRTC) and we still fail.

Since gen6, there has been a magic register bit to change the
interpretation of the tiling mode between X and Y for BLT operations.
With the advent of DRI3 and scanouts supporting Y, enabling support at
last appears interesting, perhapss even by default for non-scanouts?

Use the correct register (Yn_01) with first half of the
Y samples instead of using the register (Yn_23) with the
second half twice when computing the green channel.
Also use the Yn_01 register name instead of Yn for the red
channel as well, just for a bit of extra consistency.

Currently we add fake modes to cater for applications that want to
change the screen size but limit themselves to only those that are
available, and do not wish to either use RandR scaling or their own. For
widescreen panels, these 4:3 aspect ratio modes require panel fitting
and so are less than satisfory. Since we add fake modes, let's add a few
common widescreen modes as well (choosing the right aspect ration for
the panel).

Sometimes we want to render with the GPU when doing a mode switch, e.g.
if we need to initialise an output surface. To do so, we need to prepare
the acceleration layer first.
Lots of thanks to Vasily for tracking this one down.

When using Xinerama, RandR is automatically disabled, and calling RR
routines will trigger an assert() because the RR keys/resources are
not set, leading to an Xserver abort.
Hotplug makes little sense without RandR, so no need to install a
udev monitor if RandR is not available, as done in sna.

In cases of stress, we use a timer to create a fake vblank event and
then we adjust the timer when it fires to match it up with the CRTC msc.
However, sometimes we fire before the vblank but less than a millisecond
and so below the precision of the timer causing us to send notifies too
early. Use a blocking vblank wait to fixup these rare cases.

Otherwise we may process a SIGIO moving the cursor away from the CRTC
causing us to remove the cursor and then process a stale pointer inside

Tried to fix it by disabling SourceValidate. However, it a direct hook
into the Damage code by miSprite that triggers the copy. Since there
appears to be no way to intervene, we just mark that copy as internal
