If a device has smooth scrolling axes, but submits scroll button events, we
convert those to motion events and update the valuators. For legacy button
events, the valuator mask is likely unset though, causing
add_to_scroll_valuator() to return early, leaving us with an empty mask.
That again skipped the rest of the code and no events were generated.
Fix it by making sure that the scroll valuator in the mask is at least
initialized to 0.
Broke evdev wheel emulation, introduced by
54476b5e44.

Too much scrolling down may eventually trigger an overflow of the valuator.
If this happens, reset the valuator to 0 and skip this event for button
emulation. Clients will have to figure out a way to deal with this, but a
scroll event from (close to) INT_MAX to 0 is a hint of that it needs to be
ignored.

Events from button-only devices still need coordinates, and they get them
from scale_to_desktop(). Therefore, a dev without valuators is not a bug.
However, a dev with valuators, but less than two of them still is a bug.
This was noticed when unplugging a "Creative Technology SB Arena Headset",
which has some BTNs and some KEYs, but no REL or ABS valuators.
It emits [BTN_3] = 0 on unplug, which would trigger the BUG_WARN.

- move pointer to VGA1
- xrandr --output VGA1 --off
Warps the pointer to the new spot and calls GPE with the x/y mask bits set.
When running through the loop to check for scroll event, this overruns the
axes and may try to emulate scroll events based on random garbage in the

As a special case, if a still physically active pointer emulated touch
has no listeners and the device is explicitly grabbed for pointer
events, create a new dix touch record for the grab only.
This allows for clients to "hand off" grabs. For example, when dragging
a window under compiz the window decorator sees the button press and
then ungrabs the implicit grab. It then tells compiz to grab the device,
and compiz then moves the window with the pointer motion. This is racy,
but is allowed by the input protocol for pointer events when there are
no other clients with a grab on the device.

All touches of an indirect device, such as a trackpad, are sent to the
same window set. When there are no active touches, a new window set is
created; otherwise, the window set of an existing touch is copied.
The current code checks for any logically active touches. This includes
touches that have physically ended but are still logically active due to
unhandled touch grabs. Instead, we want a new window set whenever there
are no physically active touches.
This change skips over logically active but pending end touches, which
are touches that have physically ended.

For expediency, it made sense to always have the X and Y axes set for
direct touch device event propagation. The last X and Y values are
stored internally. However, indirect device touch event propagation
does not depend on the touch's X and Y values. Thus, we don't need to
set the values for every indirect touch event.
On top of this, the previous X and Y values aren't stored for indirect
touches, so without this change the axes get erroneously set to 0.
