I promised to update libraries to contain new candidates and repeated/added some tests...

The updated test report (draft) is here

  https://github.com/mbroz/PHCtest/blob/master/output/phc_round2.pdf

The runtime measurement of used memory should be probably compared with limits just
posted here by Steve (but is it seems to fit quite well).

Anyway, in short:

- added separate tests for optimized variants (Argon-AESNI, Lyra2-SSE, POMELO-SSE, yescrypt-SSE)

- updated to tweaked versions, added "new" algorithms (Argon2*, Catena*fly)

- no problems with Dieharder run

- a lot of illustrative graphs produced

- battcrypt, MAKWA, Parallel and yescrypt produces the same output on big-endian system.
  All other candidates are broken there (probably quite easy fixes possible).

- Some candidates need code fixes to be usable in Linux (and with gcc compiler in general).
  (Argon/Argon2i is the most problematic. See section 1.3 in document and separate patches in git.)

- I added some test case for my intended use (KDF for LUKS) for few functions.

Please let me know if it is useful (and correct me if something is wrong there or should
be added).
(It was intended as appendix in some work about KDF replacement but it can extend
existing tests as well or so ...)

Thanks,
Milan
