When an RandR shared pixmap is created in rrCreateSharedPixmap, it has a refcnt
of 1. Then, PixmapShareToSlave bumps the refcnt to 2. However, there's no
corresponding PixmapUnshareFromSlave where the refcnt can be decreased again,
and there's no convenient common place where the refcnt can be decremented when
the slave pixmap is destroyed.
Fix this by just unreffing the pixmap twice in RRCrtcDetachScanoutPixmap.

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.

The transformation matrix we previously stored was a scaled matrix based on

required (or desired).
Store two separate matrices, one as requested by the client, one as the
product of [scale . matrix . inv_scale]. Depending on the type of movement,
apply the respective matrix.
For relative movements, also drop the translation component since it doesn't

XTest devices are the first ones in the list, being initialised together
with the master devices. If we disable the devices in-order and a device has
a button down when being disabled, the XTest device is checked for a
required button release (xkbAccessX.c's ProcessPointerEvent). This fails if
the device is already NULL.
Instead of putting the check there, disable the devices in the reverse order
they are initialised. Disable physical slaves first, then xtest devices,
then the master devices.

Absolute devices may send relative events depending on the mode (synaptics
by default, wacom per option). The relative events are added to the previous
position, converted into device coordinates and then scaled into desktop
coordinates for pointer movement.
Because the device range must be mapped into the desktop coordinate range,
this results in uneven scaling depending dimensions, e.g. on a setup with
width == 2 * height, a relative movement of 10/10 in device coordinates
results in a cursor movement of 20/10 (+ acceleration)
Other commonly user-visible results:
* the touchpad changing acceleration once an external monitor as added.
* drawing a circle on a wacom tablet in relative mode gives an ellipsis in
the same ratio as the desktop dimensions.
Solution: pre-scale the incoming relative x/y coordinates by width/height
ratio of the total desktop size. Then add them to the previous
coordinates and scale back with the previous mapping, which will undo the
pre-scaling and give us the right movement.

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.
