The comparison function must return an integer less than, equal to, or
greater than zero if the first argument is considered to be respectively
less than, equal to, or greater than the second.

Move the entire request into the kernel and move changed parameters
back when done.
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.

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.
