Added support for streaming arrays of streamables; extracted the efficient

streamable serialization code from PolyStreamableList and made it
generally available; modified the StreamableArrayList to support
heterogenous lists (because they don't have much more overhead than
homogenous lists now) which allows us to remove PolyStreamableList
entirely.
