This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
This decouples wlr_output_enable and the wl_global.
The previously internal functions wlr_output_(destroy/create)_global are
exposed and used automatically in the wlr_output_layout to create/tear
down the global.
The compositor can handle them itself if it wants to, but I think this
is the right moment to create/destroy the wl_output when the
wlr_output_layout is used.
Same as what atomic_crtc_set_cursor does

Add a remote display name argument to wlr_wl_backend_create.
If NULL is passed to the wayland backend at all times, creating a
wayland backend *after* the compositor was started up, would require
changing the WAYLAND_DISPLAY environment variable.
