remove a dependency of GraphicBuffer (libui) on Parcel (libbinder).

Add a Flattenable interface to libutils which can be used to flatten
an object into bytestream + filedescriptor stream.
Parcel is modified to handle Flattenable. And GraphicBuffer implements
Flattenable.

Except for the overlay classes libui is now independent of libbinder.
