So when we VT switch back and attempt to flush the input devices,
we don't succeed because evdev won't return part of an event,
since we were only asking for 4 bytes, we'd only get -EINVAL back.
This could later cause events to be flushed that we shouldn't have
gotten.
This is a fix for CVE-2013-1940.

So in the cold plug server shutdown case, we reap the resources
before we call CloseScreen handlers, so the config->randr_provider
is a dangling pointer when the xf86CrtcCloseScreen handler is called,
however in the hot screen unplug case, we can't rely on automatically
reaped resources, so we need to clean up the provider in the xf86CrtcCloseScreen
case.
This patch provides a cleanup callback from the randr provider removal
into the DDX so it can cleanup properly, this then gets called by the automatic
code for cold plug, or if hot unplug it gets called explicitly.
Fixes a number of random server crashes on shutdown

dmx-config.h is a server header which includes dix-config.h. That again
defines a bunch of server-specifics, including setting the size of XID to
32 bit.
libX11 uses unsigned long (8 bits on x86_64). XGCValues thus ends up being
16 bytes smaller in xdmxconfig than in the library, causing garbage to be
sent to the server.

DGA only handles master devices but it does intercept slave device events as
well (since the event handlers are per event type, not per device).
The DGA code must thus call into UpdateDeviceState to reset the button/key
state on the slave device before it discards the remainder of the event.
Test case:
- Passive GrabModeSync on VCP
- Press button
- Enable DGA after ButtonPress
- AllowEvents(SyncPointer)
- Release button
The button release is handled by DGAProcessPointerEvent but the device state
is never updated, so the slave ends up with the button permanently down.
And since the master's button state is the union of the slave states, the
master has the button permanently down.

This should fix a regression in the 1.13.0 release: commit
5f5bbbe543 removed a code path used by Xvfb
and made it use the default one when initializing extensions. However, this
meant the GLX extension was not initialized anymore since it is not part of
the `staticExtensions' array.
Since it is not possible to just add it to that array after commit
aad428b8e2, adopt an approach similar to
xwin's and xquartz's and initialize the extension from vfb's `InitOutput'.

This solves a race if we are trying to dynamically power off

as good as we can do for now.
The GPU probing causes the devices to be powered up, then when
we scan the PCI bus we get the correct information from the kernel,
rather than a bunch of 0xff due to the device being powered off.

This call is required for external drivers (specifically NVIDIA) that do
not share the xfree86 infrastructure to update the desktop dimensions.
Without it, the driver would update the ScreenRecs but not update the total
dimensions the input code relies on for transformation.
This call is a thin wrapper around the already-existing internal call and
should be backported to all stable series servers, with the minor ABI bump.

Let's say - purely for the sake of argument, mind you - that you had a
server GPU with anemic memory bandwidth, and you walked up to it and
plugged in a monitor that was 1920x1080 because that's what happened to
be on the crash cart. Say the memory bandwidth is such that anything
larger than 1280x1024 gets filtered away. Now you're in trouble,
because the established timings section includes a 720x400 mode because
that's what DOS 80x25 is, and that happens to just about match the
physical aspect ratio.
Instead let's reuse the logic from the existing aspect-match path: pick
the larger mode of either the physical aspect ratio or 4:3.
