 This is a prerequisite of Trac #526 (CNAME query processing).

 While I tried to add tests for #526, I found that auth/query_unittest
 had become quite big and complicated.  The mock zone is now quite big
 and unreadable.  Since it's quite likely that we'll add more test cases
 (not only for CNAME), I think it's time to refactor it so that it can be
 more extendable and understandable.

 I'm giving this (sub)task an estimation of 2 (again, it's my personal
 estimation).
