4131dd2950 vfb: use screenInfo insead of pointer passed to InitOutput()
We only have one global screenInfo struct ever, and many other parts of the
Xserver can only operate on global screenInfo, so it's time to phase out
this extra pointer. Once the same has done on the other DDXes, it will
be dropped from InitOutput()'s parameter list.

967ae609b6 dix: drop DDXBEFORERESET symbol
Reduce complexity for things that really don't matter much:

The ddxBeforeReset() function is called when the Xserver going to reset
(new server generation). Right now, the only DDX really needing that is
Xwin, on all the others it's just no-op.

We've got an extra complicated build logic, which ifdef's out this all when
Xwin isn't built at all. The saving is extremely minimal - just skipping
few stub functions, which in most sessions aren't even called.

Therefore, get rid of this extra complexity that isn't giving us any
notable gain.

f0257bfe93 xvfb: replace xallocarray() by calloc()
Only key difference that calloc(), in contrast to rellocarray(),

machines, and it's safer programming practise to always allocate
zero-initialized, so one can't forget to do it explicitly.

a83f56eb92 vfb: use calloc() instead of malloc()
Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.

The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.

The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

b2a0d6065d vfb: add DRI3/glamor support
This commit adds DRI3/glamor support, effectively translating into
hardware GPU support.

Theoretically it should be possible to use DRM/GPU drivers such as
virtio or vgem, although only the intel i915 driver is currently tested.

Since Xvfb does no modeset, it opens the render node. Currently that is
fixed to "/dev/dri/renderD128" and will be tweaked with future commits.

Specific use-cases are left for the reader - testing glamor, GL driver
or others.

v2: Drop GLAMOR_NO_XV, use GLAMOR_FOR_XORG instead (Michel Dänzer)
v3: Fix build w/o glamor
v4:
 - Split out glamor dependency patch for meson (Pekka)
 - Enhance commit message (Pekka)
 - Use O_CLOEXEC with open() (Pekka)
 - Enhance error path, memory leak comments (Pekka)

d8ec33fe05 glx: Use vnd layer for dispatch (v4)
The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.

Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.

v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.

v3: Add/remove the XID map from the vendor private thunk, not the
backend. (Kyle Brenneman)

v4: Fix deletion of ghost contexts (Kyle Brenneman)

e957a2e5dd dix: Add hybrid full-size/empty-clip mode to SetRootClip
216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.

Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.

Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.

This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.
