Import the skein hashing algorithm, based on the threefish block cipher

Connect it to userland (libmd, libcrypt, sbin/md5) and kernel (crypto.ko)

Support for skein as a ZFS checksum algorithm was introduced in r289422
but is disconnected because FreeBSD lacked a Skein implementation.

A further commit will enable it in ZFS.

Implement SHA-512 truncated (224 and 256 bits)

This implements SHA-512/256, which generates a 256 bit hash by
calculating the SHA-512 then truncating the result. A different initial
value is used, making the result different from the first 256 bits of
the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on
64bit platforms, so the result is a faster 256 bit hash.

The main goal of this implementation is to enable support for this
faster hashing algorithm in ZFS. The feature was introduced into ZFS
in r289422, but is disconnected because SHA-512/256 support was missing.
A further commit will enable it in ZFS.

This is the follow on to r292782

Rewrite HISTORY: The SHA256 code first appeared in 6.0, and the SHA512
code in 9.0; neither existed in FreeBSD 4.0.

Add SHA512 (Actually, this is Colin Percival's code for SHA256, with
relevant constants changed).

While I'm here clean up the tests and Makefile.
