Delay expose or configure processing until the event queue is empty so
that we don't end up processing a long series of events one at a
time. Expose events already have a check waiting for the last in a
series, this further improves that by discarding multiple
series of events.

If we end up reading all pending X events in the course of other server
execution, then our notify FD callback won't get invoked and we won't
process them. Fix this by noting that there are queued events in the
block handler, setting the poll timeout to zero and queuing a work
proc to clear the event queue.
v2: use a work proc to clear the event queue rather than doing it in
the block handler directly.

Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new
pixmap.
Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.
Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)
glamor (static wrapping)
driver (static wrapping)
It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.
[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes
ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.

Currently Xephyr doesn't inherit host X server's keymap, which

using xcb-xkb to retrieve the needed XKB controls.
This implementation is analogous to Xnest one at commit 83fef4235.

This patch introduces a new flag ATTR_KEY for hotplugged input devices,
so we can better distinguish between real keyboards (i.e. devices with
udev property ID_INPUT_KEYBOARD="1") and other key input devices like
lid switches, power buttons, etc.
All supported hotplug backends (udev, hal, and wscons) will set both
flags ATTR_KEY and ATTR_KEYBOARD for real keyboards, but udev backend
will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input
devices (hal and wscons will set both flags in any case). With this
distinction, kdrive input hotplugging mechanism will be allowed to only
grab real keyboards, as other key input devices are currently not
supported.
In order to don't break current behaviour, this patch will replace all
ATTR_KEYBOARD occurrences with ATTR_KEY in hw/xfree86/common/xf86Xinput.c.

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.
