Move the desktop_arrange_all_views() call outside layers_arrange() into
a new function, output_update_usable_area(). The new function currently
does exactly what layers_arrange() used to, but will be expanded in a
later commit.
Add output_update_all_usable_areas(), which is the same as calling
output_update_usable_area() for each output, but only calls
desktop_arrange_all_views() once.

...and thus simplify the usage of wlr_scene_node_at(). Specifically:
- desktop.c: in get_cursor_context() use node-description for
layer-surfaces and layer-popups. This lays the foundations for a
pointer-enter-event being sent when a new layer-surfaces appears under
the pointer (even if the pointer doesn not move).
- layers.c:
* Iterate over `struct wlr_scene_tree *layer_tree[]` rather than
`struct wl_list layers[]` when arranging layers to avoid surfaces
being out of sync with nodes
* Set signal handlers after scene node creation to avoid configure
race conditions
* Handle scene-node destroy event rather than event of
`struct wlr_layer_surface_v1`
* Arrange layers on map and unmap
* Handle client request for layer-change
Fixes issue #667
Previously, motion events for a cursor which had been pressed on a surface
and then moved out of the surface were only sent for XDG and X11 surfaces.
This patch includes layer surfaces as well.
Fixes#483
Currently if a surface with exclusive zone is created prior to regular
surfaces, the size of the exclusize zone does not affect the usable area
for regular surfaces. This for example results in notifications being
rendered over the statusbar.
This commit fixes the issue by handling the surfaces with exclusive
zones first.
Fixes#420.
Steps to reproduce crash:
- run nested with two outputs (e.g. WLR_WL_OUTPUTS=2 ./build/labwc)
- start panel on one output (e.g. waybar)
- close that output

This allows popups to be rendered above views and other layers. Without
this, the popups of a layer-shell application in the bottom layer would
render below views, which does not seem right. For example, consider the
case of a panel with right-click popups.
