bbu: reserve upper 16 bits for handler specific flags
Let the handler store 16 bit of handler specific flags in
the generic handler struct. The setup functions of some
bbu handlers let the user specify a flags field. With this
change they can now pass generic and handler specific flags
in a single variable without having to use a second parameter.
