83a86c5ce4 Always mix in additional entropy into keymaster. 
This makes AndroidKeyStore Cipher and KeyGenerator implementations mix
in additional entropy into keymaster's RNG regardless of whether they
were provided with a SecureRandom instance.

In practice, they are always provided with a SecureRandom instance.
However, to be safe, when no SecureRandom instance is provided the
code now uses a platform-default SecureRandom implementation.

6358b881f2 Handle KM_ERROR_CALLER_NONCE_PROHIBITED. 
This converts KM_ERROR_CALLER_NONCE_PROHIBITED into
InvalidAlgorithmParameterSpec, as expected by the contract of JCA
Cipher.
