Paul Stewart ac0ffbf62c Separate the binder backend from android_engine
Create a pure virtual class "KeystoreBackend" which supplies the
crypto methods used by android_engine.  Create a KestoreBackendBinder
class which implements the binder backend as a no-op change that
will allow future backends to be added.
