ticket: 6660
subject: Minimal support for updating history key
target_version: 1.8
tags: pullup

Add minimal support for re-randomizing the history key:

* cpw -randkey kadmin/history now works, but creates only one key.
* cpw -randkey -keepold kadmin/history still fails.
* libkadm5 no longer caches the history key. Performance impact
is minimal since password changes are not common.
* randkey no longer checks the newly randomized key against old keys,
and the disabled code to do so in setkey/setv4key is gone, so now
only kadm5_chpass_principal_3 accesses the password history.
