improve [un]marshalling of non-binder objects
this change introduces a new class LightFlattenable<> which is
a protocol to flatten simple objects that don't require
binders or file descriptors; the benefit of this protocol is that
it doesn't require the objects to have a virtual table and give us
a consitant way of doing this.
we also introduce an implementation of this protocol for
POD structures, LightFlattenablePod<>.
Parcel has been update to handle this protocol automatically.
Sensor, Rect, Point and Region now use this new protocol.
