Alan Somers 2391e536c0 Fix multiple bugs with ctld's UCL parsing 
* Don't segfault when parsing a misformatted auth-group section
* If the config file specifies a chap section within a target but no
  auth-group, create a new anonymous auth-group.  That matches the
  behavior with non-UCL config files.
* Protect some potential segfaults with assertions
