Subject: [PATCH v4 0/3] crypto: streebog - add Streebog hash function

Add GOST/IETF Streebog hash function (GOST R 34.11-2012, RFC 6986)
generic hash transformation with appropriate testmgr and tcrypt
tests and vectors.

Streebog Hash Function (GOST R 34.11-2012, RFC 6986) is one of the Russian
cryptographic standard algorithms (called GOST algorithms).

Intended user is the IMA subsystem, which does not need any particular
patching besides adding the hash names into Hash Info arrays, this is also
done in this patchset.

  https://tools.ietf.org/html/rfc6986

Tested using testmgr and tcrypt on (LE) x86_64, arm, arm64, and (BE) s390x
in qemu.

Changes from v1:
- Fix of big-endian problem in add512.
- More architectures are tested, including big-endian and 32-bit.

Changes from v2:
- Register hash in Hash Info for use by IMA.
- Add hmac() tests.

Changes from v3:
- Remove not needed includes, and register, inline, const, ULL, and
  __aligned specifiers.
- Covert define macros into functions.
- Use block size define instead of a number.
- Rename algorithm names sb256, sb512 to streebog256, streebog512.
- Rename bufsize to a more meaningful name (fillsize).
- Prefix all static functions names with streebog_.

  crypto: streebog - add Streebog hash function
  crypto: streebog - register Streebog in hash info for IMA
  crypto: streebog - add Streebog test vectors
