I checked the JDK javadocs for all the engineInit()s. I have added a test case
in the mauve suite (gnu.testlet.gnu.javax.crypto.jce.TestOfCipherEngineInit)
modelling the behaviour mentioned there for engineInit(int, Key, SecureRandom)
and engineInit(int, Key, AlgorithmParameterSpec, SecureRandom). I have also
verified most of the behaviour the test case expects against the JDK and other
providers as well. I just sent a patch on cp-patches that IMO models executes
this logic properly:

Please have a look when you get a chance and comment.
