Description

Connectionless transport types such as UDP has a problem with the current API because there's no way for IoHandler bound to an acceptor to send a message before a client sends data. This issue has been discussed in this thread:

Here's my idea:

* Add ConnectionlessIoAcceptor which extends IoAcceptor
* Add ConnectionlessIoAcceptor.newSession(SocketAddress remoteAddress, SocketAddress localAddress)

Users will be able to create a session object by calling newSession so easily that they can call write() method.

WDYT?

I like it :o) But in my mind, localAddress is optional (useless ?) because the IoAcceptor is already bound and you want to use this bound local address.

[Trustin Lee]

You have to specify local address because you can bind multiple handlers to multiple local addresses.

[Alban Peignier]

You're perfectly right. So +1 for me.

Decided to resolve this issue in 0.8.

Added IoAcceptor.newSession(remoteAddress, localAddress) which returns IoSession.
Transport types other than connectionless ones throw UnsupportedOperation.

I didn't extend IoAcceptor because it is much simpler this way.
