modesetting relied on randr_crtc->scanout_pixmap being consistent with
calls to SetScanoutPixmap, which is very fragile and makes a lot of
assumptions about the caller's behavior.
For example, RRReplaceScanoutPixmap(), when dropping off with !size_fits,
will set randr_crtc->scanout_pixmap = NULL and then call SetScanoutPixmap.
Without this patch, drmmode_set_scanout_pixmap_(cpu/gpu) will think that
there is no scanout pixmap to tear down, because it's already been set to
NULL.
By keeping track of the scanout pixmap in its internal state, modesetting
can avoid these types of bugs and reduce constraints on calling
conventions.

This is an ABI break, in that we now pass NULL to a function that hasn't
accepted it before.
Alex Goins had a different patch for this but it wasn't symmetrical, it
freed something in a very different place than it allocated it, this
attempts to retain symmetry in the releasing of the backing bo.

One of the lacking features with output offloading was
that screen rotation didn't work at all.
This patch makes 0/90/180/270 rotation work with USB output
and GPU outputs.
When it allocates the shared pixmap it allocates it rotated,
and any updates to the shared pixmap are done using a composite
path that does the rotation. The slave GPU then doesn't need
to know about the rotation and just displays the pixmap.
v2:
rewrite the sync dirty helper to use the dst pixmap, and
avoid any strange hobbits and rotations.

Based on code by Keith Packard, Eric Anholt, and Jason Ekstrand.
v2:
- Fix double free and flip_count underrun (caught by Mario Kleiner).
- Don't leak flip_vblank_event on the error_out path (Mario).
- Use the updated ms_flush_drm_events API (Mario, Ken).
v3: Hack around DPMS shenanigans. If all monitors are DPMS off, then
there is no active framebuffer; attempting to pageflip will hit the
error_undo paths, causing us to drmModeRmFB with no framebuffer,
which confuses the kernel into doing full modesets and generally
breaks things. To avoid this, make ms_present_check_flip check that
some CRTCs are enabled and DPMS on. This is an ugly hack that would
get better with atomic modesetting, or some core Present work.
v4:
- Don't do pageflipping if CRTCs are rotated (caught by Jason Ekstrand).
- Make pageflipping optional (Option "PageFlip" in xorg.conf.d), but
enabled by default.
v5: Initialize num_crtcs_on to 0 (caught by Michel Dänzer).

In the new KMS APIs, the legacy drmModeSetCursor ioctl actually waits
for a vblank after changing the cursor image before returning, meaning
that the X server, in attempting to hide the cursor before updating
its image, actually makes that hide *visible* for a full vblank.
It's unknown why the X server does this by default, but turn it off.
If we're with a legacy driver that doesn't support the modern
drmModeSetCursor by waiting for a vblank before returning, we're going
to get a tiny bit of tearing on the cursor plane. But between tearing
with a new cursor image and tearing with a blank cursor image, I'd
rather the former.
The only proper solution to this is an atomic ioctl that page flips
all planes, including the cursor plane, at vblank time and at the same
time.

This is derived from the intel driver DRI2 code, with swapchain and
pageflipping dropped, functions renamed, and vblank event management
shared code moved to a vblank.c for reuse by Present.
This allows AIGLX to load, which means that you get appropriate

more easily.
