Michael Munday dccd99e89d sha3: add optimized implementation for s390x 
Message-security-assist extension 6 adds support for the SHA-3 and
SHAKE algorithms. This CL allows the sha3 package to use these new
features.

David Leon Gil 1b32d8b50a go.crypto/sha3: update to sync with draft FIPS-202 
1. API:

This exposes a minimal API: the SHA-3 functions implement hash.Hash. The
SHAKE functions implement a new "ShakeHash" interface that implements
io.Reader, io.Writer, and Reset().

(The previous Barrier() function has been removed.)

(Alternative proposal: Don't implement io.Reader, but instead provide a
"Digest(d []byte) error" function that performs a hash.Hash style copy.
Somewhat more minimal, but very easy to use incorrectly.)

2. Tests

Added the complete set of ShortMsgKATs from
   https://github.com/gvanas/KeccakCodePackage

3. Correctness

In sync with draft FIPS-202.

4. Documentation

A summary of the security properties of the SHA-3 and SHAKE functions is
provided in doc.go; some concrete recommendations as well.

Fixes 8563.
