30bff1d0f4 Extend AES-CMAC routines to support 256-bit keys
omac1_aes_256() and omac1_aes_vector() can now be used to perform
256-bit CMAC operations similarly to the previously supported 128-bit
cases.

eefec1e40b AES: Extend key wrap design to support longer AES keys
This adds kek_len argument to aes_wrap() and aes_unwrap() functions and
allows AES to be initialized with 192 and 256 bit KEK in addition to
the previously supported 128 bit KEK.

The test vectors in test-aes.c are extended to cover all the test
vectors from RFC 3394.

4bf3910574 Move AES-CCM implementation into src/crypto
This is a generic AES CCM implementation that can be used for other
purposes than just implementing CCMP, so it fits better in a separate
file in src/crypto.

77b2c81275 Add aes_gmac() as a wrapper for AES GMAC operations using GCM
This is otherwise identical to aes_gcm_ae() but does not use the
plain/crypt pointers since no data is encrypted.

d140db6adf Add support for using 192-bit and 256-bit keys with AES-GCM
This adds 192-bit and 256-bit key support to the internal AES
implementation and extends the AES-GCM functions to accept key length to
enable longer AES key use.
