grab->type is only non-zero for passive grabs. We're checking an active grab
here, so we need to check if the touch mask is set on the grab.
Test case: grab the device, then start two simultaneous touches. The
grabbing client won't see the second touchpoints because grab->type is 0
and the second touch is not an emulating pointer.

ProcessTouchEvents() calls UDS for all touch events, but if the event type
was switched to TouchUpdate(pending end) UDS is a noop.
Daniel Drake found this can cause stuck buttons if a touch grab is
activated, rejected and the touch event is passed to a regular listener.
This sequence causes the TouchEnd to be changed to TouchUpdate(pending end).
The actual TouchEnd event is later generated by the server once it is passed
to the next listener. UDS is never called for this event, thus the button
remains logically down.
A previous patch suggested for UDS to handle TouchUpdate events [1], however
this would release the button when the first TouchEvent is processed, not
when the last grab has been released (as is the case for sync pointer
grabs). A client may thus have the grab on the device, receive a ButtonPress
but see the button logically up in an XQueryPointer request.
This patch adds a call to UDS to TouchEmitTouchEnd(). The device state must
be updated once a TouchEnd event was sent to the last grabbing listener and
the number of grabs on the touchpoint is 0.

TouchListenerGone cleans up if a client disappears. Having this in
FreeGrab() triggers cyclic removal of grabs, emitting wrong events. In
particular, it would clean up a passive grab record while that grab is
active.

Introduced in xorg-server-1.13.99.901-2-g9ad0fdb. Storing the grab pointer
in the listener turns out to be a bad idea. If the grab is not an active
grab or an implicit grab, the pointer stored is the one to the grab attached
on the window. This grab may be removed if the client calls UngrabButton or
similar while the touch is still active, leaving a dangling pointer.
To avoid this, copy the grab wherever we need to reference it later. This
is also what we do for pointer/keyboard grabs, where we copy the grab as
soon as it becomes active.

A sync grab is the owner once it gets events. If it doesn't replay the
event it will get all events from this touch, equivalent to accepting it.
If the touch has ended before XAllowEvents() is called, we also now need to
send the TouchEnd event and clean-up since we won't see anything more from
this touch.

If a device is frozen in results to a grab, we need to enqueue the events.
This makes things complicated, and hard to follow since touch events are now
replayed in the history, pushed into EnqueueEvent, then replayed later
during PlayReleasedEvents in response to an XAllowEvents.
While the device is frozen, no touch events are processed, so if there is a
touch client with ownership mask _below_ the grab this will delay the
delivery and potentially screw gesture recognition. However, this is the
behaviour we have already anyway if the top-most client is a sync pgrab or
there is a sync grab active on the device when the TouchBegin was generated.
(also note, such a client would only reliably work in case of ReplayPointer
anyway)

If the device is currently grabbed as the result of a passive grab
activating, do not prepend that grab to the listeners (unlike active grabs).
Otherwise, a client with a passive pointer grab will prevent touch grabs
from activating higher up in the window stack.

This places a pointer to the grab related to a TouchListener directly
in the TouchListener structure rather than hoping to find the grab
later on using the resource ID.
Passive grabs have resource ID in the resource DB so they can be
removed when a client exits, and those resource IDs get copied when
activated, but implicit grabs are constructed on-the-fly and have no
resource DB entry.

GetTouchEvents has plenty of side effects such as moving the pointer or

replaying. The only reason for calling it was to generate a DCCE event,
but GetTouchEvents doesn't even do that right (we might need a DCCE
event even when replaying a master event, or clients could interpret
valuator data incorrectly).
This discussion is moot at the moment anyway, since DeliverTouchEvents
doesn't appear to deliver DCCE events.

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.

Note: this commit is a retroactive commit extracted from a series of ~50

Pointer processing tree is roughly:
- ProcessOtherEvents
- ProcessTouchEvents
- DeliverTouchEvents
- DeliverTouchBeginEvent|DeliverTouchEndEvent|...
- DeliverOneTouchEvent
Also hooks up the event history playing to the right function now.
