b1eaa502df events: reorganize getters 
Restructure the getters for event fields to
be more targeted at particular event types.

Update all callers, and replace all direct
event struct access with getters.

As a side-effect, this drops some unused getters.

f1cf0eb3fc Drop gdk_set/get_show_events 
We don't need a separate api to turn on debugging
for events.

31bf9da63a Strip const from GdkEvent 
Events are refcounted structs, and we generally don't
pass these as const.

1026bfb1ac events: Drop all setters 
GdkEvent is now truly readonly.

92288205d4 events: Drop target and related target 
GTK no longer uses this, so we can drop it.

e5223b1cee main: Stop calling gdk_event_set_target 
GTK is no longer relying on this.

2416b4e2a0 Stop using gdk_event_get_target 
We can now get the target widget from the gesture
that we are using to find the event in the first
place.

2bac066a63 gesture: Keep the target widget for events 
We already store the events; keep the target widget
in addition. This is a step towards getting rid of
gdk_event_get_target.

cd601ffb9e eventcontroller: Make the target widget available 
Make it possible for event controllers to obtain
the target widget during handle_event.

e54e48f6d1 Explicitly pass the target to handle_event 
Pass the event propagation target explicitly down to
the event controllers. This is a step towards getting
rid of gdk_event_set_target.

b38869b3aa Stop looking at the related target for filtering 
We are now sending crossing events (which are the only ones
where a related target makes sense) via handle_crossing.

d063b6b6cc Reinstate filtering for crossing events 
The event propagation limit should apply to crossing events
as well.

23c67f8c67 New focus change handling 
Instead of relying on gdk's antiquated crossing events,
create a new GtkCrossingData struct that contains the
actual widgets, and a new event controller vfunc that
expects this struct. This also saves us from making sense
of X's crossing modes and details, and makes for a
generally simpler api.

The ::focus-in and ::focus-out signals of GtkEventControllerKey
have been replaced by a single ::focus-change signal that
takes GtkCrossingData as an argument. All callers have
been updated.

1b2289ad9b Stop using gtk_get_event_target 
This is just a thin wrapper around gdk_event_get_target,
so use that directly.

dd251d85c4 Pass translated coordinates outside the event 
We want to make events readonly, so stop translating
their coordinates and instead pass the translated
coordinates separately, when propagating events.

c343031a0e Stop using g_object_ref/unref on events 
Use gdk_event_ref/unref instead of g_object_ref/unref.
Events will stop being object soon.

835556c270 Drop gdk_event_new and gdk_event_copy

59cc216985 display: Stop using gdk_event_copy 
Events are effectively readonly in GDK now, so we can just
take a reference, no need for a copy.

79b4510c6d x11: change event translator interface 
Make the event translator return a new event, instead of
filling in a half-constructed one.

Update the two implementation in GdkX11Display and
GdkDeviceManagerXI2.

15501afdbb x11: Change the wm protocols filter api 
Instead of passing a half-constructed event and expect
it to be filled in, pass the surface as in argument, and
add an out argument for a newly constructed GdkEvent.

94fe0944cc x11: Don't pass a GdkEvent to shape cache filters

047c18844c x11: Don't generate GDK_DESTROY events

anyway.

4cf63f3eb3 wip: Use event constructors in the testsuite 
This doesn't work because the constructors aren't exported,
so remove the gestures text temporarily, until we figure
out how to deal with it.
