* add OverlapChecker, move the test of overlap AFTER the directive setup process, change key of configs to allow multiple same key * glitch when rebase. init of Config should include the default host * add tests for the registering of configuration rename multicast in 'unbound'. add comments on the validator * - merged zoneAddr and addrKey that are very similar - move maps of Validator to zoneAddr, avoinding need to have string representation of zoneaddr - moving key build for saving Config at Config side instead of dnsContext * - UT on saving config is now useless. * - cannot cleanup access to Configs after setup. Deferred function to Start, use it * - cleanup register unit tests. remove useless function * - address comments of review. name of validator, comments, simplify registerAndCheck * - fixes after review. renaming a function and a comment
