  Log:
  Add Geom Based Disk Encryption to the tree.
  
  This is an encryption module designed for to secure denial of access
  to the contents of "cold disks" with or without destruction activation.
  
  Major features:
  
     * Based on AES, MD5 and ARC4 algorithms.
     * Four cryptographic barriers:
          1) Pass-phrase encrypts the master key.
          2) Pass-phrase + Lock data locates master key.
          3) 128 bit key derived from 2048 bit master key protects sector key.
          3) 128 bit random single-use sector keys protect data payload.
     * Up to four different changeable pass-phrases.
     * Blackening feature for provable destruction of master key material.
     * Isotropic disk contents offers no information about sector contents.
     * Configurable destination sector range allows steganographic deployment.
  
  This commit adds the kernel part, separate commits will follow for the
  userland utility and documentation.
  
  This software was developed for the FreeBSD Project by Poul-Henning Kamp and
  NAI Labs, the Security Research Division of Network Associates, Inc.  under
  DARPA/SPAWAR contract N66001-01-C-8035 ("CBOSS"), as part of the DARPA CHATS
  research program.
  
  Many thanks to Robert Watson, CBOSS Principal Investigator for making this
  possible.
