[glib] GIOChannel: Add missing annotations

    GIOChannel: Add missing annotations
    
    The various read and write methods have several out arguments which were not
    previously marked as such. Also, as GIOChannel supports binary data with a NULL
    encoding, the buffers need to be uint8 arrays instead of utf8 strings.
