Pull up r22782, r22784, r23610 from trunk, with additional test suite
changes to compensate for the existence of the api.0/ unit tests that
removed for 1.8.  Don't pull up the kadmin CLI changes for now.

 ticket: 6626
 subject: Restore interoperability with 1.6 addprinc -randkey
 tags: pullup
 target_version: 1.8

 The arcfour string-to-key operation in krb5 1.7 (or later) disagrees
 with the dummy password used by the addprinc -randkey operation in
 krb5 1.6's kadmin client, because it's not valid UTF-8.  Recognize the
 1.6 dummy password and use a random password instead.

 Improve the mechanism used for addprinc -randkey.  In the kadmin
 server, if the password is null when creating a principal, treat that
 as a request for a random key.  In the kadmin client, try using the
 new method for random key creation and then fall back to the old one.
