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 6 years ago			`/*`
			`* This an unstable interface of wlroots. No guarantees are made regarding the`

This simplifies the DRM and Wayland backends since they were creating textures from the byte buffer anyway.
