Subject: [PATCH v3 5/8] lib/crypto: Add SHA3 kunit tests
Add a SHA3 kunit test, providing the following:
(*) A simple test of each of SHA3-224, SHA3-256, SHA3-384, SHA-512,
SHAKE128 and SHAKE256.
(*) NIST 0- and 1600-bit test vectors for SHAKE128 and SHAKE256.
(*) Output tiling (multiple squeezing) tests for SHAKE256.
(*) Standard hash template test for SHA3-256.
(*) Standard benchmark test for SHA3-256.
gen-hash-testvecs.py is also modified to be able to generate SHAKE hashes
because Python's hashlib requires the output digest size supplying for
those two algorithms as they produce arbitrary length digests.
