Stephane Landelle 8d4db050f3 Have hosts file support for DnsNameResolver, close #4074 ... Motivation: On contrary to `DefaultNameResolver`, `DnsNameResolver` doesn't currently honor hosts file. Modifications: * Introduce `HostsFileParser` that parses `/etc/hosts` or `C:\Windows\system32\drivers\etc\hosts` depending on the platform * Introduce `HostsFileEntriesResolver` that uses the former to resolve host names * Make `DnsNameResolver` check his `HostsFileEntriesResolver` prior to trying to resolve names against the DNS server * Introduce `DnsNameResolverBuilder` so we now have a builder for `DnsNameResolver`s * Additionally introduce a `CompositeNameResolver` that takes several `NameResolver`s and tries to resolve names by delegating sequentially * Change `DnsNameResolver.asAddressResolver` to return a composite and honor hosts file Result: Hosts file support when using `DnsNameResolver`. Consistent behavior with JDK implementation.		2015-12-17 15:15:42 +01:00
