Peter Hutterer 2bb282cd45 Xi: only activate the device grab if we don't already have one
If the device is already grabbed, don't activate the passive grab, it screws
with our event masks. Just deliver to the grabbing client instead.

Peter Hutterer 209b3d613a Xi: hook up touch ownership handling
Ownership changes don't get processed directly when they happen, instead the
DIX submits an ownership event which goes through ProcessTouchEvents and
ProcessTouchOwnershipEvents.
Then on the required events are generated and sent to clients.

Peter Hutterer 1894468c2b Xi: hook up pointer emulation for emulating touches
Includes a hack for implicit grab activation, because integrating this
requires a larger rewrite and I'm not sleeping enough as it is.
Right now, we deliver the event and check before/after if there is an
implicit grab on. If one activated, then store the event in the grab and
switch the listener type to a grab listener.

Peter Hutterer e389a19a73 Process and deliver touch events
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.

Peter Hutterer dbfd7b37a0 Xi: make UpdateDeviceState aware of touch events
Update the logical button state for pointer-emulating events. Button state
must be kept separate from the ButtonClassRec to avoid clearing the button
state on a touch end if there is a physical button still down.

And obviously don't change the button state if we're currently replaying the
event history for some client.

Daniel Stone 3fb258ca28 input: add a TouchClassRec to the devices
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.

Peter Hutterer 84db813b9d Hook up TouchBegin/Update/End events
The are the same as device events internally but require the touch ID
separately from the detail.button field (the protocol uses the detail field
for the touch id).
For simpler integration of pointer emulation we need to set the
detail.button field while keeping the touchid around.

Add the three new touch event types to the various places in the server
where they need to be handled. The actual handling of the events is somewhat
more complicated in most places.

Peter Hutterer 3304bbff9b Input: Add smooth-scrolling support to GetPointerEvents
For scroll wheel support, we used to send buttons 4/5 and 6/7 for
horizontal/vertical positive/negative scroll events.  For touchpads, we
really want more fine-grained scroll values.  GetPointerEvents now
accepts both old-school scroll button presses, and new-style scroll axis
events, while emitting both types of events to support both old and new
clients.

This works with the new XIScrollClass to mark axes as scrolling axes.
Drivers mark any valuators that send scroll events with SetScrollValuator.
(Currently missing: the XIDeviceChangeEvent being sent when a driver changes
a scroll axis at run-time. This can be added later.)

Note: the SCROLL_TYPE enums are intentionally different values to the XI2
proto values to avoid copy/overlapping range bugs.
