Make AES-CMAC context slightly smaller.
...
Since AES-CMAC is based on AES-128, the state specific to AES-CMAC can overlap the latter parts of the AES context structure, which are used only by AES-192 or AES-256.

Implement "KDF in Counter Mode" from NIST SP 800-108.
...
This is currently instantiated with HMAC-SHA256 as the pseudo-random function, but is implemented using a template so that other PRFs could also be used.

Update HMAC-MD5 code to support processing a message in multiple parts.
...
This is implemented in the common HMAC code and can apply to the other hash algorithms as well, but the header and tests are currently only implemented for HMAC-MD5.
