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}

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.
Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

Make sure sector zero is protected if it contains metadata.
Lower WARNS for gbde to 3 on non-i386 archs. rijndael-fst is evil
but appearntly does the right thing and passes the test-vectors.
MFC Candidate.
Replace ARC4 with SHA2-512.
Change lock-structure encoding to use random ordering rather for obscurity.
Encrypt lock-structure with AES/256 instead of AES/128.
Change kkey derivation to be MD5 hash based.
Watch for malloc(M_NOWAIT) failures and ditch our cache when they happen.
Remove clause 3 of the license with NAI Labs consent.
Many thanks to "Lucky Green" <shamrock@cypherpunks.to> and "David
Wagner" <daw@cs.berkeley.edu>, for code reading, inputs and

This code has still not been stared at for 10 years by a gang of
hard-core cryptographers. Discretion advised.
NB: These changes result in the on-disk format changing: dump/restore needed.
