On X11 this is something the windowing system does for us, which the
wayland backend should emulate, being grabs completely client-side.
So, if the grab and current focus windows differ, make sure we emit
focus/crossing events as it corresponds to the grab device.
This was being done so only on pointers. Internally, a GdkDeviceGrabInfo
is kept for each of the master pointer/keyboard, failing to do this for
keyboards results in a stuck keyboard grab.

On wl_keyboard.key/modifiers, we're just forgetting about currently
pressed mouse buttons. Fix this by storing button and key modifiers
separately, and put these together when creating the GdkEvents.
I was getting really weird values for scale for the blank cursor used
when hiding the cursor in a GtkEntry when typing, this was caused
by gdk_wayland_device_update_window_cursor sending random values
when the returned buffer was NULL.
We fix this by just not sending any buffer or scale updates in this
case.
During drag operations from another client, we currently set no window as
the DnD source. There's paths in upper layers though that rely on it being
set, just that we don't trigger these yet.
Support scaling of cursors created from themes. The default scale is
always 1, but if the pointer cursor surface enters an output with a
higher scale, load the larger version of the cursor theme and use the
image from that theme.
This assumes the theme size is set to one that fits with an output scale
= 1.

Only static cursors are supported in gdk_device_grab() so far. Obey the
cursor that gdk_device_grab() specifies, which may be different to
the pointer window one. As soon as the grab is gone, the pointer window
cursor will be restored as usual.

On DnD, pointer_handle_leave may be triggered without the pointer actually
leaving the window, and pointer_handle_enter() happening after intra-window
DnD won't actually manage to update the cursor (it does nothing directly,
and to the upper layers the cursor is still the same and consistent, so no
attempt will happen).
To fix this, keep the pointer cursor on leave, and ensure it is updated
on enter. The pointer cursor will be updated to any current new one through
the enter/motion events generated if it needs be.

The wl_data_source is retrieved from the selection object for the DnD
selection, and used to initiate a drag. When the drag is finished, a
button release or touch end event is synthesized to finish the DnD
operation after the compositor grab is gone.

The wayland specific clipboard functions have been replaced by something
more similar to the hooking the win32 backend does, which allows for just
using the default GtkClipboard code in GTK+. As a consequence, the
wayland-specific GtkClipboard implementation is now gone.
https://bugzilla.gnome.org/show_bug.cgi?id=697855
This has been made to work similarly to X11, requests for the data device
contents are notified through GDK_SELECTION_REQUEST events, the data stored
in the GDK_SELECTION property as a reaction to that event is then stored
into the wayland selection implementation, and written to the fd when
requested/available.
https://bugzilla.gnome.org/show_bug.cgi?id=697855
_gdk_wayland_device_get_button_press_serial() has been replaced by
_gdk_wayland_device_get_implicit_grab_serial(), which takes a touch/pointer
event and figures out the relevant serial, and
_gdk_wayland_device_get_last_implicit_grab_serial() which returns
the most recent serial.
The button press serial was currently used when operating popping up
xdg_shell/surface popups and window menus, so this is now touch aware, of
some sort.

Delay the keyboard settings creation until we're delivering the key
press. This means we don't have to create the settings for a server that
sends us repeat information.
The way that GtkTextView et al pop up their context menu is to first
query to see if the clipboard has some text, and if so, enable the Paste
menu item. But since the Wayland backend hasn't had the greatest
selection and clipboard code, the callback for the clipboard got dropped
on the floor.
Add some simple code to respond to the TARGETS selection.
This makes right-clicking on a GtkTextView work fine.
Weston numbers its touch sequences ids starting from 0, thus simply
setting the GtkEvents touch.sequence to the touch id value typically
causes gdk_event_get_event_sequence to return NULL. Unfortunately this
confuses other parts of GDK.
As both weston & mutter keep the sequence id between 0..max_dev_touches
-1 simply use + 1 to keep the id > 0. While this isn't entirely correct
(compositor could send -1 as the touch id), this keeps the touch id in
gtk tied to the touch id from weston which is useful for debugging. A
more thorough solution could be done when it turns out this is an issue
in practise

The events are routed through a new slave device with type
GDK_SOURCE_TOUCHSCREEN, minimal tracking of touches is done
to keep the state for each of those.
https://bugzilla.gnome.org/show_bug.cgi?id=728426
The master pointer/keyboard pair should never disappear or be
inconsistent. The seat capabilities are now reflected through
slave devices, those may come and go freely as the seat
capabilities change. This also enables adding further capabilities
to handle eg. touch.

Lots of code, including dragging code in GtkWindow, use these
fields. Setting them to 0 causes lots of strange and weird bugs.
Use the same "hack" from query_device_state of just using
win_x / win_y for now. We'll convert this to the proper fake root
coordinate system used by get_root_coords in the next commit.
