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.

Pointer passive grabs may be changed by the grabbing client. This allows
for a selecting client to change an implicit grab to an active grab,
which is the mechanism used for pop-up windows like application menus.
We need to do the same thing with touches. If the grabbing client is the
owner of a touch sequence, change the listener record to reflect the new
grab. If the grabbing client is not the owner, nothing changes for the
touch.

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.

Previously, we only had one idle alarm that was triggered for all devices,
whenever the user used any device, came back from suspend, etc.
Add system SyncCounters for each device (named "DEVICEIDLETIME x", with x
being the device id) that trigger on that device only. This allows for
enabling/disabling devices based on interaction with other devices.
Popular use-case: disable the touchpad when the keyboard just above the

For driver debugging, it is helpful to know whether the driver has actually
submitted an event to the server. dtrace hooks can help here.
Note that GetPointerEvents and friends may also be triggered by the server
for other emulated devices, some care must be taken when analysing the
results.
Additional difficulty: proximity events have a run-time assigned type, so
this may make automatic detection a tad harder. If in doubt, go for any

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.

This change ensures that the server's notion of the grab time is the

Add two new legal values for the initial connection's byteOrder field,
'r' and 'R'. These act like 'l' and 'B' respectively, but have the side
effect of forcing the client to be treated as non-local. Forwarding
proxies should attempt to munge the first packet of the connection
accordingly; older servers will reject connections thusly munged, so the
proxy should fall back to passthrough if the munged connection attempt
