======================= Warning ==========================

  ======================= Warning ==========================
     All hash codes in the database are now kept in world
     compatible base64 format (no = filling). This means that
     all FileSets will be updated and if you are running
     verify jobs, you must do an InitCatalog.
     Authentication uses the new algorithm, but should be
     backward compatible with 1.38.x
  ===========================================================

- Modify the authentication routines so that the 1.39.15 Director
  always runs with the compatible binary to base64 code (same as
  the rest of the world).  It will however detect if an SD or
  FD is running the old code and if that is the case, will use
  the old algorithm for authentication.  However, all consoles must
  use the compatible algorithm, and all data entered into the database
  (all hash signatures, MD5, SHA1, ..., and all FileSet hashes) will
  use the compatible algorithm.
- Rename the cram_md5 routine names to be slightly more appropriate
  to what they are doing (challenge and respond).
- Robert committed his #ifdef and header cleanup.
