Fixing DNS memory leaks.

Browse source 
Some of the changes only clean up at termination to make perftools
happt, but there were some "real" leaks as well.

This fixes all DNS leaks I could reproducem, including most likely
what's reported in #534. Closing #534.

I'm also adding a new btest subdir core/leaks with tests requiring
perftools support. These don't compare against base lines but abort
whenever perftools reports a leak (with stack information to track it
down). Right now, these are passing.
