* core: allow all CIDR ranges in zone specifications Allow (e.g.) a v4 reverse on a /17. If a zone is specified in such a way a FilterFunc is set in the config. This filter is checked against incoming queries. For all other queries this adds a 'x != nil' check which will not impact performace too much. Benchmark function is added as well to check for this as wel. Add multiple tests in tests/server_reverse_test.go. Benchmark shows in the non-reverse case this hardly impact the speed: ~~~ classless: pkg: github.com/coredns/coredns/core/dnsserver BenchmarkCoreServeDNS-4 1000000 1431 ns/op 16 B/op 1 allocs/op pkg: github.com/coredns/coredns/core/dnsserver BenchmarkCoreServeDNS-4 1000000 1429 ns/op 16 B/op 1 allocs/op master: pkg: github.com/coredns/coredns/core/dnsserver BenchmarkCoreServeDNS-4 1000000 1412 ns/op 16 B/op 1 allocs/op pkg: github.com/coredns/coredns/core/dnsserver BenchmarkCoreServeDNS-4 1000000 1429 ns/op 16 B/op 1 allocs/op ~~~ * README.md updates
