The Wayland protocol does not share XI2's wealth of information
about individual devices, but it does provide discriminating
information about the source for scroll events. Pass this on to
the application by creating separate slave devices for these,
and setting them as source device on the scroll events.
These devices can be discriminated by their input-source property:
wheel - GDK_SOURCE_MOUSE
finger - GDK_SOURCE_TOUCHPAD
continuous - GDK_SOURCE_TRACKPOINT

fix up
Calling gdk_gl_context_realize() should always result in a valid result,
so we need to provide a default implementation, to avoid a call to a
NULL function pointer.
Given that Wayland has no global coordinate, the only way for gdk to
retrieve the monitor a window last entered is to retrieve it from the
GdkWaylandWindow itself.
Implement the backend specific get_monitor_at_window() to return the
monitor that was last entered by the window.

In Wayland, surfaces get an enter/leave notification each time they
enter or leave an output.
Add an API to GdkWaylandWindow to retrieve the output the window has
last entered.

Some backends (namely Wayland) do not support global coordinates so
using the window position to determine the monitor will always fail on
such backends.
In such cases, the backend itself might be better suited to identify
the monitor a given window resides on.
Add a vfunc get_monitor_at_window() to the display class so that we can
use the backend to retrieve the monitor, if the backend implements it.

The GdkDragContext should only listen to GDK_GRAB_BROKEN events sent to
its own pointer device. It turns out that the passive key grabs mistake
GDK into sending a GdkEventGrabBroken on the master keyboard, which the
DnD machinery mistakes as a signal to cancel the operation.

Only generate crossing events on wl_touch.down for the virtual master
device used for touch events, and only whenever this virtual device
actually moves across surfaces. This behavior resembles better what is
expected in X11, where the pointer is warped to the touch position
on XITouchBegin.
This avoids the double emission of leave events when the pointer
emulating touch is lifted, that crossing event will be instead
generated when/if the focus surface changes.

This is required for proper integration with any other library/application that
may perform wayland API calls and poll() the wayland fd from multiple threads.
Using wl_display_dispatch{_queue}() is thread-safe if not mixed with custom
poll() usage, which GSource/GMainContext does.
Essentially, the problem is that multiple threads polling and reading
the same fd is extremely racy. Use the wayland provided API for allowing
concurrent access to the wayland display fd.
See the wayland man pages for wl_display_prepare_read(),
wl_display_cancel_read() and wl_display_read_events() for more details.

WINBOOL is MinGW-specific, so change it to BOOL, which is universally
available.
Also, Visua Studio is more picky on where __stdcall (WINAPI) is placed, so
fix that to be in-sync with what is done in the other sources.
Use of g_signal_handlers_disconnect_by_func() needs to do more work than
necessary to find all the matching handlers. Instead, just hold on to the
signal identifier and remove it directly so we hit the fast path.
Not terribly ground breaking in terms of performance gains, but its done
enough to be worthwhile.

The active keyboard grab can be spared then. This way the passive
key grabs allow other key combinations (eg. alt-tab) that are not
mandatory to grab here.
The wayland specification for discrete step information for scroll and
other axes reads:
| The discrete value carries the directional information. e.g. a
| value of -2 is two steps towards the negative direction of this axis.
mutter sets a value of 1 for SCROLL_DOWN events and -1 for SCROLL_UP
events.
gdkdevice Wayland backend does the opposite, it translates a positive
discrete value as SCROLL_UP and a negative value as SCROLL_DOWN, which
ends up inverting the scrolling direction.
Fix the logic in gdkdevice Wayland to use a positive value as
SCROLL_DOWN and a negative value as SCROLL_UP so that it matches mutter
and weston logic.
