Currently, we dispatch the events on the wayland display server ourselves. This is fine when using the cairo backend of libdecor, as it does the same thign we do, but other backends may require other things to be dispatched. This commit lets libdecor dispatch events instead through libdecor_get_fd and libdecor_dispatch, which should hopefully makes things less sketchy.
