99c40431b9 Use InetSocketAddress.getHostName() instead of getHostString()
Related: #3478

Motivation:

DefaultNameResolver uses InetSocketAddress.getHostString() instead of
getHostName(). Because Netty uses the DefaultNameResolver by default and
getHostString() is available only since Java 7, a user cannot use Netty
on Java 6 anymore.

Modifications:

Use InetSocketAddress.getHostName() which is practically same and also
is available in Java 6.

Result:

Netty 4.1 runs on Java 6 again.

e848066cab Name resolver API and DNS-based name resolver
Motivation:

So far, we relied on the domain name resolution mechanism provided by
JDK.  It served its purpose very well, but had the following
shortcomings:

- Domain name resolution is performed in a blocking manner.
  This becomes a problem when a user has to connect to thousands of
  different hosts. e.g. web crawlers
- It is impossible to employ an alternative cache/retry policy.
  e.g. lower/upper bound in TTL, round-robin
- It is impossible to employ an alternative name resolution mechanism.
  e.g. Zookeeper-based name resolver

Modification:

- Add the resolver API in the new module: netty-resolver
- Implement the DNS-based resolver: netty-resolver-dns
  .. which uses netty-codec-dns
- Make ChannelFactory reusable because it's now used by
  io.netty.bootstrap, io.netty.resolver.dns, and potentially by other
  modules in the future
  - Move ChannelFactory from io.netty.bootstrap to io.netty.channel
  - Deprecate the old ChannelFactory
  - Add ReflectiveChannelFactory

Result:

It is trivial to resolve a large number of domain names asynchronously.
