Reword surface pool allocation helpers so that to allow for a simple form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a somewhat more elaborated/flexible form with optional allocation flags and precise GstVideoInfo specification. This is an API/ABI change, and SONAME version needs to be bumped.
