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. Reviewed by: cem Sponsored by: ScaleEngine Inc. Differential Revision: https://reviews.freebsd.org/D6166
