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.

PR: 191174
Submitted by: Franco Fichtner <franco at lastsummer.de>

Remove the RFC 1319 MD2 Message-Digest Algorithm routines from libmd.

1. The licensing terms for the MD2 routines from RFC is not under a BSD-like
license. Instead it is only granted for non-commercial Internet
Privacy-Enhanced Mail.
2. MD2 is quite deprecated as it is no longer considered a cryptographically
strong algorithm.

Discussed with: so (cperciva), core

Remove reference to no longer existing document.

Imported libmd. This library contains MD2, MD4 and MD5.
These three boggers pop up all over the place all of the time, so I
decided we needed a library with them. In general they are used for
security checks, so if you use them you want to link them static.
