gesture: Simplify gesture/widget interaction public API
...
The propagation phase property/methods in GtkEventController are gone,
This is now set directly on the GtkWidget add/remove controller API,
which has been made private.
The only public bit now are the new functions gtk_gesture_attach() and
gtk_gesture_detach() that will use the private API underneath.
All callers have been updated.

widget: Keep a widget reference around _gtk_widget_run_controllers()
...
The widget may be destroyed within the loop, in reaction to the signals
sent by the controllers. Protect against that.

gesture: Add explanatory note in GtkGesture::end
...
Explain that this signal may be triggered by an extra touch that causes
the gesture to surpass GtkGesture:n-points.

gesture: Cancel sequences that make a gesture exceed the number of touches as they happen
...
This makes it possible to track those through gtk_gesture_handles_sequence(),
without guessing from last event type or sequence state.

widget: Change slightly the gesture cancellation policy in a same widget
...
Within a widget, if a gesture accepts a sequence, it would previously
cancel every other gesture that not in the same group. Change this to
only cancelling gestures that previously claimed the gesture, and let
gestures with state=NONE for that sequence remain like that.
This enables late recognition of gestures, even on the presence of
another gesture group that was more eager at claiming the gesture.
One usecase is user-defined panning gestures on scrolledwindows,
if ::capture-button-press is TRUE (eg. the default), the gesture is
claimed early in order to consume the button press, but that would
tipically make every other gesture group deny the sequence. With
this change, the pan gesture can keep state=NONE, and later claim
the sequence for itself if the panning gesture is recognized.
Also, do not propagate state=DENIED to every gesture in the widget,
that was unintended.

gesture: Handle GDK_TOUCH_CANCEL events
...
The wayland windowing backend emits such events for instance, so
have gestures cancel the sequence as those events get through.

gesture: Protect against odd window hierarchies
...
If no match is found with the gesture widget when poking the event
window parents, bail out safely instead of falling in an infinite
loop. This was seen on Mutter.

Prevent subclassing of gestures
...
For now, at least. We do this by hiding the instance and
class structures in private headers.

The utility of those signals is somewhat dubious now that there is
gtk_gesture_group(), so make that the only way to coordinate gestures.
The cooperation model offered by gtk_gesture_group() is flexible
enough,
