Evan Hunt dc6202479f remove find_deepest_zonecut() from qpcache 
because the cache no longer stores delegation (parent-side) NS rrsets,
and authoritative (child-side) NS rrsets don't affect recursion,
it no longer makes sense for qpcache_find() to look for NS rrsets
and return DNS_R_DELEGATION. that code has been removed.

the cache still does search for covering DNAME records. the
check_zonecut() function has been renamed to check_dname() for clarity.

related changes:
- one test case has been removed from the mirror system test, because it
  tested the behavior of a cached delegation.
- query_checkrrl() and rpz_rrset_find() have been updated so they no
  longer expect cache responses to have DNS_R_DELEGATION response codes.

This test checks whether zones configured with "type mirror;" behave as
expected.

ns1 is an authoritative-only server.  It only serves the root zone, which is
mirrored by ns3.

ns2 is an authoritative-only server.  It serves a number of zones, some of which
are delegated to it by ns1 and used in recursive resolution tests aimed at ns3
while others are only served so that ns3 has a primary server to mirror zones
from during various tests of the mirror zone implementation.

ns3 is a recursive resolver.  It has a number of mirror zones configured.  This
is the only server whose behavior is being examined by this system test.
