Release the global interpreter lock during encryption, decryption, and hashing.
These are the easy ones. We don't release the GIL on cipher initialization,
hash initialization, or hash finalization, because those functions might make
Python API calls, and we would need to add a mechism for re-acquiring the GIL
in those cases.
