Modify the back stack and result code propagation in the screen lock scenarios. - EncryptionInterstitial now propagates the result of ChooseLock* request instead of always returning RESULT_OK. - ChooseLockGeneric now treats CHOOSE_LOCK_REQUEST and ENABLE_ENCRYPTION_REQUEST the same (since encryption can be a proxy for ChooseLock*). This means ChooseLockGeneric will now stay on back stack when going back from ChooseLock*, just like the case (indirectly) through EncryptionInterstitial.
