Merge the camellia-ccm branch to trunk. Since there are no IANA
assignments for Camellia-CCM enctypes or cksumtypes yet, they are disabled in a default build. They can be made available by defining (via CPPFLAGS) local-use enctype numbers for the enctypes and cksumtypes. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24295 dc483132-0cff-0310-8789-dd5450dbe970
