1) performance changes. 	a) do C_Decrypt in the handUnwrap case on it's own session so we don't  single thread through the code. 	b) reuse the session created for the symKey when importing the key from data.
1) performance changes.
	a) do C_Decrypt in the handUnwrap case on it's own session so we don't
 single thread through the code.
	b) reuse the session created for the symKey when importing the key from data.

2) robustness changes.
	a) try different ways of getting the signature length if non-complient
 tokens don't present the modulus to us.
	b) Recover from state buffers changing sizes on us in the middle of
GetOperationState().
