This patch introduces "by8" AES CTR mode AVX optimization inspired by
Intel Optimized IPSEC Cryptograhpic library. For additional information,
please see:
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22972
The functions aes_ctr_enc_128_avx_by8(), aes_ctr_enc_192_avx_by8() and
aes_ctr_enc_256_avx_by8() are adapted from
Intel Optimized IPSEC Cryptographic library. When both AES and AVX features
are enabled in a platform, the glue code in AESNI module overrieds the
existing "by4" CTR mode en/decryption with the "by8"
AES CTR mode en/decryption.
On a Haswell desktop, with turbo disabled and all cpus running
at maximum frequency, the "by8" CTR mode optimization
shows better performance results across data & key sizes
as measured by tcrypt.
The average performance improvement of the "by8" version over the "by4"
version is as follows:
For 128 bit key and data sizes >= 256 bytes, there is a 10-16% improvement.
For 192 bit key and data sizes >= 256 bytes, there is a 20-22% improvement.
For 256 bit key and data sizes >= 256 bytes, there is a 20-25% improvement.
A typical run of tcrypt with AES CTR mode encryption of the "by4" and "by8"
optimization shows the following results:

crypto: Incorporate feed back to AES CTR mode optimization patch
Specifically, the following:
a) alignment around main loop in aes_ctrby8_avx_x86_64.S
b) .rodata around data constants used in the assembely code.
c) the use of CONFIG_AVX in the glue code.
d) fix up white space.
e) informational message for "by8" AES CTR mode optimization
f) "by8" AES CTR mode optimization can be simply enabled
if the platform supports both AES and AVX features. The
optimization works superbly on Sandybridge as well.
Testing on Haswell shows no performance change since the last.
Testing on Sandybridge shows that the "by8" AES CTR mode optimization
greatly improves performance.

There's no need for the K_table to be made of 64-bit words. For some
reason, the original authors didn't fully reduce the values modulo the
CRC32C polynomial, and so had some 33-bit values in there. They can
all be reduced to 32 bits.
Doing that cuts the table size in half. Since the code depends on both
pclmulq and crc32, SSE 4.1 is obviously present, so we can use pmovzxdq
to fetch it in the correct format.
This adds (measured on Ivy Bridge) 1 cycle per main loop iteration
(CRC of up to 3K bytes), less than 0.2%. The hope is that the reduced
D-cache footprint will make up the loss in other code.
Two other related fixes:
* K_table is read-only, so belongs in .rodata, and
* There's no need for more than 8-byte alignment

The DRBG test code implements the CAVS test approach.
As discussed for the test vectors, all DRBG types are covered with
testing. However, not every backend cipher is covered with testing. To
prevent the testmgr from logging missing testing, the NULL test is
registered for all backend ciphers not covered with specific test cases.
All currently implemented DRBG types and backend ciphers are defined
in SP800-90A. Therefore, the fips_allowed flag is set for all.

All types of the DRBG (CTR, HMAC, Hash) are covered with test vectors.
In addition, all permutations of use cases of the DRBG are covered:
* with and without predition resistance
* with and without additional information string
* with and without personalization string
As the DRBG implementation is agnositc of the specific backend cipher,
only test vectors for one specific backend cipher is used. For example:
the Hash DRBG uses the same code paths irrespectively of using SHA-256
or SHA-512. Thus, the test vectors for SHA-256 cover the testing of all
DRBG code paths of SHA-512.
