When using type annotations, the ABI of type being annotated and a new
type introduced from annotation should match.
In case of enumerations, the most common ABI, and probably the only one
currently used in practice with gtk, corresponds to -fno-short-enums
compiler option. It uses int as the underlying type of enum, bumping it
up to unsigned int, long int or unsigned long int, in that order, when
necessary.
Thus, when annotating a field of integer type with an enum type, it is
never correct to annotate field smaller than int, because it changes the
ABI from perspective on introspection.
The gint8 phase field in GdkEventTouchpadSwipe and GdkEventTouchpadPinch
structures have been previously annotated in such a way, and this change
removes this annotation to restore ABI compatibility.
Size of structures before (which does not match C):
```
>>> Gdk.EventTouchpadPinch.__info__.get_size()
104
>>> Gdk.EventTouchpadSwipe.__info__.get_size()
88
```
Size of structures after (which does match C):
```
>>> Gdk.EventTouchpadPinch.__info__.get_size()
96
>>> Gdk.EventTouchpadSwipe.__info__.get_size()
80
```
Fixes issue #57.
These states will be consumed by GtkWindow in order to
have better edge management on tiling situations. Their
values are supplied by the compositor, and will be send
through and X11 Atom or a Wayland protocol extension.

GDK_PAD_BUTTON*,RING and STRIP will be emitted respectively when
pad buttons, rings or strips are interacted with. Each of those
pad components belong to a group (a pad can contain several of
those), which may be in a given mode. All this information is
contained in the event.
GDK_PAD_GROUP_MODE is emitted when a group in the pad switches
mode, which will generally result in a different set of actions
being triggered from the same buttons/rings/strips in the group.

Windows save in hardware_keycode an information which is not so low
level and some application require the hardware scancode.
As Windows provides this information save it in GdkEventPrivate
and provide a function to get this information.
For no Windows system the function return the hardware_keycode instead.

And use it to handle kinetic scrolling in the GtkScrolledWindow.
However, dropping the delta check causes the X11-based kinetic
scroll to break since we don't have the stop event here. Correct handling of
xf86-input-libinput-based scroll events is still being discussed.

Each gesture type has its separate GdkEvent struct, and begin/update/
end/cancel event types.
There is support for multi-finger swipe (3-4 fingers), and 2-finger
rotate/pinch gestures.
GDK_EVENT_2BUTTON_PRESS and GDK_EVENT_3BUTTON_PRESS can't be used from
some bindings because they'd translate to something syntactically
invalid. Add GDK_EVENT_DOUBLE_BUTTON_PRESS and
GDK_EVENT_TRIPLE_BUTTON_PRESS aliases to work around that.

Anytime a touch device interacts, the crossing events generation
will change to a touch mode where only events with mode
GDK_CROSSING_TOUCH_BEGIN/END are handled, and those are sent
around touch begin/end. Those are virtual as the master
device may still stay on the window.
Whenever there is a switch of slave device (the user starts
using another non-touch device), a crossing event with mode
GDK_CROSSING_DEVICE_SWITCH may generated if needed, and the normal
crossing event handling is resumed.
This commit introduces GDK_TOUCH_BEGIN/UPDATE/END/CANCEL
and a separate GdkEventTouch struct that they use. This
is closer to the touch event API of other platforms and
matches the xi2 events closely, too.
