8254c3c5d3 Fix C++ includability of crypto headers with static array sizes
C99 allows array function parameters to use the static keyword for their
sizes. This tells the compiler that the parameter will have at least the
specified size, and calling code will fail to compile if that guarantee is
not met. However, this syntax is not legal in C++.

This commit reverts r300824, which worked around the problem for
sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can
be used in headers as a static array size, but will still compile in C++
mode.

0144ad3e78 Connect the SHA-512t256 and Skein hashing algorithms to ZFS
Support for the new hashing algorithms in ZFS was introduced in r289422
However it was disconnected because FreeBSD lacked implementations of
SHA-512 (truncated to 256 bits), and Skein.

These implementations were introduced in r300921 and r300966 respectively

This commit connects them to ZFS and enabled these new checksum algorithms

This new algorithms are not supported by the boot blocks, so do not use them
on your root dataset if you boot from ZFS.

b468a9ff1d 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.
