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

Browse Source 
cperciva's libmd implementation is 5-30% faster

The same was done for SHA256 previously in r263218

cperciva's implementation was lacking SHA-384 which I implemented, validated against OpenSSL and the NIST documentation

Extend sbin/md5 to create sha384(1)

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

* LITTLE_ENDIAN and that the two (BYTE_ORDER and LITTLE_ENDIAN) are
* equivilent.
*
* If your system does not define the above, then you can do so by
* hand like this:
*
* #define LITTLE_ENDIAN 1234
* #define BIG_ENDIAN 4321
*
* And for little-endian machines, add:
*
* #define BYTE_ORDER LITTLE_ENDIAN
*
* Or for big-endian machines:
*
* #define BYTE_ORDER BIG_ENDIAN
*
* The FreeBSD machine this was written on defines BYTE_ORDER

* <machine/endian.h> where the appropriate definitions are actually
* made).
