output: refactor frame submission API
This is necessary for direct scan-out and other upcoming features. This patch changes the output API to look like the wl_surface API. Outputs now have some double-buffered state: the frame to be submitted (currently only wlr_renderer frames are supported) and the damaged region. To attach a pending frame, use wlr_output_attach_render. To set the pending damaged region, use wlr_output_set_damage. To submit the pending state, call wlr_output_commit. This will submit the pending frame to the backend. To migrate from the old API to the new one: - Replace wlr_output_make_current calls by wlr_output_attach_render - Replace wlr_output_swap_buffers calls by wlr_output_set_damage and wlr_output_commit
