Binder copies transactions directly from the sender buffer to the target buffer and then fixes up BINDER_TYPE_PTR and BINDER_TYPE_FDA objects. This means there is a brief time when sender pointers and fds are visible to the target process. This series reworks the the sender to target copy to avoid leaking any untranslated sender data from being visible in the target.
