New Mechanisms subgroup Part 3 or 4, new AES

Part 3 New AES Mechanism: All these mechanisms are reasonably straight forward, and can be added using standard templated for their type.
The first 3 are MACing mechanism.
The last is an encryption mechanism.
CKM_AES_GMAC This is a signing mechanism with a CK_AES key.
It takes no parameters.
Used by IPsec.
GCM (Galois/Counter Mode) for Message Authentication Code (MAC).
It is a special case of GCM: The MAC is computed on the "Additional Authenticated Data" passed in via the mechanism parameter.
There is no plaintext or ciphertext.
Reference: http://en.wikipedia.org/wiki/Galois/Counter_Mode CKM_AES_XCBC_MAC This is a signing mechanism with a CK_AES key.
It takes no parameters.
Extended CBC mode (Ciphertext Block Chaining) for MAC.
RFC 3566.
Reference: http://www.ietf.org/rfc/rfc3566.txt CKM_AES_XCBC_MAC_96 CKM_AES_XCBC_MAC_96 is a special case used with IPsec.
128-bit result truncated to 96 bits.
CKM_AES_XTS This is an encryption/decryption mechanism with a CK_AES key.
It takes not paramters.
AES using XTS, Ciphertext Stealing Mode.
IEEE P1619 standard.
It's a non-expanding cipher, meaning the length of the ciphertext is the same as the plaintext, and the ciphertext is also a MAC.
