Tests in fast/events/touch have been enabled on GTK+ now that touch
support is implemented, and thus all expected bits are there.

* platform/gtk/GtkTouchContextHelper.cpp:
* platform/gtk/GtkTouchContextHelper.h: Add helper object to track all touchpoints, handy
when creating WebTouchEvents.
* GNUmakefile.list.am:
* PlatformGTK.cmake:
* bindings/gobject/GNUmakefile.am: Add touch related code and idls to build, those are
necessary now that GTK+ implements touch events.

Even though WebKit1 GTK code doesn't implement touch events,
Fix build if ENABLE_TOUCH_EVENTS is present for WK2.

In GTK+ >= 3.4.0, GdkEventTouch is available to inform about multitouch events. Use these to implement
touch events on this platform. If a touch is left unhandled and is the "pointer emulating" one, mouse
events will be generated as a fallback.

* GNUmakefile.list.am:
* PlatformGTK.cmake:
* Shared/gtk/NativeWebTouchEventGtk.cpp:
* Shared/NativeWebTouchEvent.h:
(WebKit::NativeWebTouchEvent::nativeEvent):
(WebKit::NativeWebTouchEvent::touchContext): Add GTK+ implementation of NativeWebTouchEvent.
* Shared/gtk/WebEventFactory.cpp:
(WebKit::touchPhaseFromEvents):
(WebKit::WebEventFactory::createWebTouchEvent): Add methods to generate WebTouchEvents out
of GdkEventTouch events, a GtkTouchContextHelper object is used to hold information about all current
touches, in order to build information about all individual touchpoints.
* Shared/gtk/WebEventFactory.h:
* UIProcess/API/gtk/PageClientImpl.cpp:
(WebKit::PageClientImpl::doneWithTouchEvent): Implement pointer emulation. If a touch event was unhandled
in DOM and pertains to the touch sequence that emulates pointer events. The event gets transformed to its
mouse event counterpart and handled by the widget again.
* UIProcess/API/gtk/PageClientImpl.h:
* UIProcess/API/gtk/WebKitWebViewBase.cpp:
(webkitWebViewBaseRealize): Listen for touch events
(webkitWebViewBaseTouchEvent):
(webkit_web_view_base_class_init): Add implementation for the touch_events() handler, this merely
lets the pageProxy handle the NativeWebTouchEvent we create to wrap the GdkEvent received.
