rS292782: Replace sys/crypto/sha2/sha2.c with lib/libmd/sha512c.c

Summary

cperciva's libmd implementation is 5-30% faster (also seen here: https://svnweb.freebsd.org/changeset/base/r263218 )

cperciva's implementation was lacking SHA-384 which I implemented
Extend sbin/md5 to create sha384(1)

In a separate commit, I will also add SHA-512/256 (required by new ZFS features)

Chase dependancies on sys/crypto/sha2/sha2.{c,h} and replace them with sha512{c.c,.h}

Will extend reviewers to include secteam@ once the first round of issues are dealt with

Test Plan

benchmark results: http://www.allanjude.com/bsd/sha512_results.txt

The output of the new SHA-384 implementation were verified against openssl sha384 and http://csrc.nist.gov/groups/ST/toolkit/documents/Examples/SHA384.pdf

Just a few comments.

lib/libmd/Makefile
40	is this tab/space matching others or is this just a phab misformating issue?
sys/conf/files
559	I don't see bde using SHA256, we should probably remove it, though maybe as a different commit? Looks like the module also compiles it. A quick compile of the module does look like it uses it.
561	I don't think you need zfs here yet. I'd add ZFS when you finally enable sha512/256 support.

lib/libmd/Makefile
40	i put a tab when I shouldn't have, fixed in my local copy, will update with other changes
sys/conf/files
559	yeah, that was already there, I didn't change it. geom_eli uses both 256 and 512, should it be listed in both places?
561	the zfs SRCS= line references both, and again, I just updated sha2.c -> sha512c.c (and changed the order to make sense). But yeah, I could remove ZFS here and readd it in the next commit.

Minor updates to address feedback from jmg@

sys/conf/files
559	bde != eli.. They are different, so commenting that eli uses 256 and 512 is unrelated to my bde comment.
561	Since you're adding the line fresh, it's best to keep it minimal.

sys/conf/files
559	that should have been a separate comment. Unrelated to geom_bde: geom_eli uses both SHA256 and SHA512, should it be listed in this file?

Update the diff to put sha384 prototypes in their own file as requested by cperciva
