Initial pass on API stability guarantees This introduces -DWLR_USE_UNSTABLE and adds information regarding the stability status to all headers. I started with a conservative set of headers to mark as stable: - types/wlr_matrix.h - util/edges.h - util/log.h - util/region.h - xcursor.h

void (*destroy)(struct wlr_backend *backend);
Rework session handling Sessions can now be retrieved from a backend in a more general manner. Multi-backend gets back its `session` field that contains the session if one was created, removing the interfacing from multi backend with the drm backend directly. This adds the possibility to use sessions even without the drm backend. It additionally fixes the bug that 2 session objects got created when WLR_BACKENDS were set to "libinput,drm". To allow vt switching without drm backend (and drm fd) on logind, start listening to PropertiesChanged signals from dbus and parse the session "Active" property when no master fd was created (this does not change current drm backend behaviour in any way).

backend: add get_drm_fd to interface This function allows backends to return the DRM FD they are using. This will allow the allocator and the renderer to use the right device.
