This eliminates dereferencing freed window pointers when there is a
flip for that window in progress. The flip will complete, and then
immediately get undone (as we can't stop an in-progress flip).
Remove the vblank->window_destroyed field as we can signal this with
vblank->window == NULL instead.
Change check to vblank->window == NULL in:
present_flip_notify
Add check for vblank->window == NULL in:
present_vblank_notify
present_execute
present_flip_notify was also using vblank->window->drawable.pScreen,
so stop doing that and use vblank->screen instead.

Based on some bugzilla scraping I did around November 2012. Of xserver
bugs in Red Hat bugzilla with an EQ size message in the log, the
distribution looked like:
String | Matches
-------------------------------------
Increasing EQ size to 512 | 460
Increasing EQ size to 1024 | 52
Increasing EQ size to 2048 | 6
Increasing EQ size to 4096 | 0
Most of the "512" ones appear to be mostly harmless, some relatively
expensive path in either rendering or resource destruction simply taking
too long due to external pressures like paging or CPU contention. So
let's raise the initial queue size, both to reduce the number of
spurious abrt reports and to drop fewer events in all but the most
pathological cases.

Since all the inb/outb/etc. use in the X server itself (except for
xf86SlowBcopy) has been replaced by calls to libpciaccess, we no
longer need to pass inline assembly files to replace the gcc inline
assembly from hw/xfree86/common/compiler.h when building Xorg itself.
The .il files are still generated and installed in the SDK for the
benefit of drivers who may use them.
Binary diff of before and after showed that xf86SlowBcopy was the
only function changed across the Xorg binary and all modules built
in the Xserver build, it just calls the outb() function now instead
of having the outb instructions inlined, making it a slightly slower
bcopy.

This patch fixes cursor jumps when there is a grab on the Xephyr window and
the pointer moves outside the window.
So on two side-by-side 640x480 screens, a coordinate of 0/481
triggers KdCursorOffscreen.
If the delta between two screens is 0, they share the same offset for
that dimension. When searching for the new screen, the loop always rules out
the current screen. So we get to the second screen, trigger the conditions
where dy <= 0 and decide that this new screen is the correct one. The result
is that whenever KdCursorOffScreen is called, the pointer jumps to the other
screen.
Change to check for dy < 0 etc. so that the cursor stays on the same screen if
there is no other screen at the target location.

A multi-head Xephyr instance has the pointer stuck on one screen
because of bad coordinate calculation. The coordinates passed to
GetPointerEvents are per-screen, so the cursor gets stuck on the left-most
screen by default.
Adjust and mark the events as POINTER_DESKTOP, so the DIX

If a screen size was specified as WxH, the loop returned early and kdOrigin
was never advanced. Thus, screen->origin was always 0 (or whatever was given
at the -origin commandline flag).
If a screen size was given with a bit depth (WxHxD), kdOrigin would always
advance by the current screen, offsetting the next screen.

If a client passes a section of memory via file descriptor and then
subsequently truncates that file, the underlying pages will be freed
and the addresses invalidated. Subsequent accesses to the page will
fail with a SIGBUS error.
Trap that SIGBUS, figure out which segment was causing the error and
then allocate new pages to fill in for that region. Mark the offending
shared segment as invalid and free the resource ID so that the client
will be able to tell when subsequently attempting to use the segment.

ProcessInputEvent() resets the device idle times. If idle time was higher than
the lower bracket, this should trigger an event in the idle time wakeup
handler.
If processing is slow, the idle time may advance past the lower bracket
between the reset and the time the BlockHandler is called. In that case, we'd
never schedule a wakeup to handle the event, causing us to randomly miss
events.
Ran tests with a neg transition trigger on 5ms with 200 repeats of the test
and it succeeded. Anything below that gets a bit tricky to make sure the
server sees the same idle time as the client usleeps for.
