Add internal AES CTR variant with 32-bit counter
...
This variant of CTR mode is used by AES-GCM-SIV. The counter is in
little-endian format and uses the first four bytes of the IV only.

Fix counter wrapping in AES GCM
...
The generic and AESNI implementations used different conventions
regarding counter wrapping in GCM. The generic code was based on
function block128_inc_be, for which the counter is a 128-bit value.
Whereas the AESNI code used intrinsic function _mm_add_epi64, and
therefore wrapping at 2^64.
In NIST.SP.800-38d the GCM specification mandates to use incrementing
function inc32, wrapping after 2^32 blocks. This commit changes both
generic and AESNI implementations to align to the specification and
adds a test vector specially crafted to start encryption with IV block
0xfffffffffffffffffffffffffffffffe.
