Daniel P. Berrange 6775e2c429 crypto: fix built-in AES decrypt function 
The qcrypto_cipher_decrypt_aes method was using the wrong
key material, and passing the wrong mode. This caused it
to incorrectly decrypt ciphertext.

Daniel P. Berrange ca38a4cc9e crypto: introduce generic cipher API & built-in implementation 
Introduce a generic cipher API and an implementation of it that
supports only the built-in AES and DES-RFB algorithms.

The test suite checks the supported algorithms + modes to
validate that every backend implementation is actually correctly
complying with the specs.
