Summary

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

535	Is this a programming error, or a run-time check? If the former, assert is fine. If the latter, then (a) it might not actually check and (b) it will lead to a program termination with an assert. Is that OK here and elsewhere?

535	Formerly, it failed at runtime. Now it's just there to catch future programming errors. See the call site at line 737.
