Allow different hash functions to be used in the NTP and cmdmon protocols. This breaks the cmdmon protocol compatibility. Extended key file format is used to specify the hash functions for chronyd and new authhash command is added to chronyc. MD5 is the default and the only function included in the chrony source code, other functions will be available from libraries.
