1e90b74683 Solve another bug in the mapping code: correctly skip lock sectors.
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.

5afa461402 Run a revision on the GBDE encryption facility.
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
suggestions.

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.
