Revamp crypto/aes
* Reorganize crypto/aes in order to separate parameters, implementations and
modes.
* Add a zero-cost abstraction over the internal representation of a block,
so that blocks can be kept in vector registers in optimized implementations.
* Add architecture-independent aesenc/aesdec/aesenclast/aesdeclast operations,
so that any AES-based primitive can be implemented, including these that don't
use the original key schedule (AES-PRF, AEGIS, MeowHash...)
* Add support for parallelization/wide blocks to take advantage of hardware
implementations.
* Align T-tables to cache lines in the software implementations to slightly
reduce side channels.
* Add an optimized implementation for modern Intel CPUs with AES-NI.
* Add new tests (AES256 key expansion).
* Reimplement the counter mode to work with any block cipher, any endianness
and to take advantage of wide blocks.
* Add benchmarks for AES.6 files changed, 1363 insertions(+), 643 deletions(-)
