This changes the implementation of AndroidKeyStore-backed Cipher and Mac to avoid throwing runtime exceptions during normal use. Runtime exceptions will now be thrown only due to truly exceptional and unrecoverable errors (e.g., keystore unreachable, or crypto primitive not initialized). This also changes the implementation of Cipher to cache any errors encountered in Cipher.update until Cipher.doFinal which then throws them as checked exceptions.
