For touch events with pointer emulation, the event that triggers the grab
(the pointer event) is not the same as the actual event (the touch event).
For replaying, we need to store the real event then.
No effective changes at this point, for the current caller event and
real_event are identical.

Does not include pointer emulation handling.
Does include partial ownership handling but not the actual processing of
ownership events.
Note: this commit is a retroactive commit extracted from a series of ~50
commits and may thus appear a bit more complicated than what you'd write out
from scratch.
Pointer processing tree is roughly:
- ProcessOtherEvents
- ProcessTouchEvents
- DeliverTouchEvents
- DeliverTouchBeginEvent|DeliverTouchEndEvent|...
- DeliverOneTouchEvent
Also hooks up the event history playing to the right function now.

If touch client has not registered for ownership events and a grab above
that client is rejected, the client needs to receive the complete event
history.
The history currently doesn't really do fancy overflow handling. We assume
that the first TOUCH_HISTORY_SIZE events are the important ones and anything
after that is dropped. If that is a problem, fix the client that takes > 100
event to decide whether to accept or reject.
Events marked with TOUCH_CLIENT_ID or TOUCH_REPLAYING must not be stored in
the history, they are events created by the DIX to comply with the protocol.
Any such event should already be in the history anyway.
A fixme in this patch: we don't have a function to actually deliver the
event yet.

DDX touch points are the ones that keep records of the driver-submitted

These structs will be used to store touch-related data, events and
information.
Drivers must call InitTouchClassDeviceStruct to set up a multi-touch capable
device.
Touchpoints for the DDX and the DIX are handled separately - touchpoints
submitted by the driver/DDX will be stored in the DDXTouchPointInfoRec. Once
the touchpoints are processed by the DIX, new TouchPointInfoRecs are created
and stored. This process is already used for pointer events with the
last.valuators field.
Note that this patch does not actually add the generation of touch events,
only the required structs.
TouchListeners are (future) recipients of touch or emulated pointer events.
Each listener is in a state, depending which event they have already
received. The type of listener defines how the listener got to be one.

The are the same as device events internally but require the touch ID

For simpler integration of pointer emulation we need to set the

where they need to be handled. The actual handling of the events is somewhat
