(#4494)  Remove some gratuitous IPv6 test failures.
(#4294)  Change special security configuration to augment existing permissions
rather than replace them.  This allows us to specify the correct ones for IPv6
testing.
(#4494)  Don't use -pool when calling condor_status in the parallel universe
tests, since it's superflous and breaks things.  (The calls themselves are
probably superflous, given the new start-up code.)
(#4494)  Don't use the AI_ADDR_CONFIG hint, since Ubuntu 10 and 12 don't react
to it the same way everybody else does.
