field in X replies from words to bytes.
One call to _XEatData is left in ephyrHostGLXGetStringFromServer where
it's already been checked for overflow, and other values have been
subtracted from it to reduce the size of data remaining to be eaten.

This reverts commit 3209b094a3. After a
long debug session by Paul Berry, it appears that this was the commit
that has been producing sporadic failures in piglit front buffer
rendering tests for the last several years.
GetBuffers may return fresh buffers with invalid contents at a couple
reasonable times:
- When first asked for a non-fake-front buffer.
- When the drawable size is changed, an Invalidate has been sent, and
obviously the app needs to redraw the whole buffer.
- After a glXSwapBuffers(), GL allows the backbuffer to be undefined,
and an Invalidate was sent to tell the GL that it should grab these
appropriate new buffers to avoid stalling.
But with the patch being reverted, GetBuffers would also return fresh
invalid buffers when the drawable serial number changed, which is
approximately "whenever, for any reason". The app is not expecting
invalid buffer contents "whenever", nor is it valid. Because the GL
usually only GetBuffers after an Invalidate is sent, and the new
buffer allocation only happened during a GetBuffers, most apps saw no
problems. But apps that do (fake-)frontbuffer rendering do frequently
ask the server for the front buffer (since we drop the fake front
allocation when we're not doing front buffer rendering), and if the
drawable serial got bumped midway through a draw, the server would
pointlessly ditch the front *and* backbuffer full of important
drawing, resulting in bad rendering.
The patch was originally to fix bugzilla:
https://bugs.freedesktop.org/show_bug.cgi?id=28365
Specifically:
To reproduce, start with a large-ish display (i.e. 1680x1050 on my
laptop), use the patched glxgears from bug 28252 to add the
-override option. Then run glxgears -override -geometry 640x480
to create a 640x480 window in the top left corner, which will work
fine. Next, run xrandr -s 640x480 and watch the fireworks.
I've tested with an override-redirect glxgears, both with vblank sync
enabled and disabled, both with gnome-shell and no window manager at
all, before and after this patch. The only problem observed was that
before and after the revert, sometimes when alt-tabbing to kill my
gears after completing the test gnome-shell would get confused about
override-redirectness of the glxgears window (according to a log
message) and apparently not bother doing any further compositing.

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

Instead of defaulting to -intel for Oaktrail, Medfield, and CDV chips,
default to -fbdev. For Poulsbo (only), attempt to use -psb if it's
installed, and fallback to fbdev otherwise. All other Intel chips
should use -intel.
This fixed an issue where -intel would load on these chips and cause a
boot failure. Newer -intel drivers avoid the boot hang, but it's still
the wrong driver to load, so why take chances.
The patch was originally created by Stefan Dirsch for OpenSUSE. We have
included it in our stable release (Ubuntu "quantal" 12.10) since
December.

If we're about to abort, we're already in the signal handler and cannot call
down to the default device cleanup routines (which reset, free, alloc, and
do a bunch of other things).
Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.
This is largely backwards-compatible, hence the input ABI minor bump only.
Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.

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.

Our in-house parfait 1.1 code analysis tool complained that every exit
path from xf86ValidateModes() in hw/xfree86/common/xf86Mode.c leaks the
storeClockRanges allocation made at line 1501 with XNFalloc.
Investigating, it seems that this code to copy the clock range list to
the clockRanges list in the screen pointer is just plain insane, and
according to git, has been since we first imported it from XFree86.
We start at line 1495 by walking the linked list from scrp->clockRanges
until we find the end. But that was just a diversion, since we've found
the end and immediately forgotten it, and thus at 1499 we know that
storeClockRanges is NULL, but that's not a problem since we're going to
immediately overwrite that value as the first thing in the loop.
So we move on through this loop at 1499, which takes us through the
linked list from the clockRanges variable, and for every entry in
that list allocates a new structure and copies cp to it. If we've
not filled in the screen's clockRanges pointer yet, we set it to
the first storeClockRanges we copied from cp. Otherwise, as best
I can tell, we just drop it into memory and let it leak away, as
parfait warned.
And then we hit the loop action, which if we haven't hit the end of
the cp list, advances cp to the next item in the list, and then just
for the fun of it, also sets storeClockRanges to the ->next pointer it
has just copied from cp as well, even though it's going to overwrite
it as the very first instruction in the loop body.
