This is useful for mock input drivers that control the server in
integration tests. Given that input submission happens on a different
thread than processing, it's otherwise impossible for the driver to
synchronize with the completion of the processing of submitted events.

The masks we end up building will occupy all 32 bits of an unsigned int,
which means we had better build the shifts out of unsigned ints, because
left-shifting a signed int all the way into the sign bit is undefined.
As discussed in issue #829 the "mi: Shortcut miDoCopy/miCopyArea based
on clipList" change leads to pointer-trails (area under pointer not
restored when it moves) when using a software cursor.
Checking pGC->pCompositeClip instead of pDstDrawable->clipList fixes
this problem.

miHandleExposures does two things: computes the region for which to
generate expose events, and (if the destination is a window) paints the
exposed regions with the background. The bit of this conditional we're
deleting here asserts that the source is either a pixmap or a window
without backing store. The only other possibility is a window _with_
backing store. In the old backing store implementation, this was where
you would recover bits from backing store. Since our "backing store" is
the redirected window pixmap, we know we've already copied all we could,
because CopyArea had already seen the entire window pixmap. So now in
that third case, we are still drawing to a pixmap (so there's no
background to paint) and we are still not generating events, so we can
exit early.
The comment above the function about recovering bits from backing store
is clearly misleading, so delete that too.
This is maybe one more comparison, but it catches FullyObscured windows
slightly earlier, so it's kind of a wash. The important thing is this
allows for paintable but unmapped windows, which will have non-empty
clipList.
Both because extension names are inconsistently capitalized on the wire,
and because the table we're walking spells it COMPOSITE not Composite.
The latter is certainly also a bug, but there's no reason for us to be
that strict.

this is a pretty modest speedup:

9236.3 21298.2 ( 2.306) 100-pixel wide double-dashed ellipse
But part of the reason it's so modest there is that the arcs are
relatively small (100 pixel diameter at line width 10, so ~6000 pixels)
and the dashes relatively large (30 on 20 off so ~6 dashes per
quadrant).
With larger arcs and finer dashes this is much more impressive. A fairly
trivial testcase of a single 15000x13000 arc with the default {2, 2}

xf86VTSwitch() calls ProcessInputEvents() before disabling a device, and
DisableDevice() calls mieqProcessInputEvents() again when flushing touches and
button events. Between that and disabling the device (which causes new events
to be refused) there is a window where events may be triggered and enqueued.
On the next call to PIE that event is processed on a now defunct device,
causing the crash.
The simplest fix to this is to discard events from disabled devices. We flush
the queue often enough before disabling that when we get here, we really don't
care about the events from this device.

RootWindow()->firstChild to DeepestSpriteWindow(). This function is only
supposed to be called from miXYToWindow which resets spriteTraceGood to 1,
thus DeepestSpriteWindow() is always the root window anyway.
What got dropped was the firstChild as the first window to handle, so we may
end up with the root window twice in the sprite trace.

This allows DDXen to override the window picking to account for
native windows not seen by the X server. The bulk of the picking logic
is exposed as a new helper function, miSpriteTrace(). This function
completes the sprite trace filled out by the caller, and can be set up
to start the search from a given toplevel window.

Printing these as ErrorF is fairly obnoxious, since it means the
non-hardware servers now spew stuff to the console for entirely routine
events. And actually, printing these at all is fairly obnoxious, since
a) we're printing a line for every extension, whether it's enabled or
not, and b) we're not actually initializing the extension at this point.

The X server still has 'unsigned long' in a few places to hold 32 bit
values. One of those is in miPutImage where it's holding the temporary
planemask for XYPixmap format images.
It computed the highest plane in the source image with 1 << (depth -
1). On 64-bit machines, taking that value and storing it in an
unsigned long promotes it to a signed 64-bit value
(0xffffffff80000000).
Then, it loops over that value, shifting one bit right each time,
waiting for it to go to zero.. That takes 64 iterations, and ends up
with some mystic planemask values *and* walking off the end of the
source image data and out into space.
A simple cast is all that is required to compute the correct initial
plane mask (0x0000000080000000), at which point the loop operates
correctly once again.
Checking the fbPutImage code, I note that this same bug was fixed
in 2006 by Aaron Plattner in commit

Looping around LoadExtension() meant that ExtensionModuleList was reallocated
on every extension. Using LoadExtensionList() we pass an array thus the
function can do the reallocation in one go, and then loop and setup the
ExtensionModuleList.

With all the logic now in place there is no need to allocate a separate
ExtensionModule to be used as a sentinel.
