crypto: support multiple threads accessing one QCryptoBlock
The two thing that should be handled are cipher and ivgen. For ivgen the solution is just mutex, as iv calculations should not be long in comparison with encryption/decryption. And for cipher let's just keep per-thread ciphers. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Daniel P.
