Add support for chunked responses

This changeset provides a simple way to implement HTTP streaming.

About the implementation:
- HttpResponse#chunked signals that the response is going to be a chunked one (i.e. "Transfer-Encoding: chunked")
- calling HttpResponse#write afterwards will write chunks to the channel
- often times streaming is continuous (i.e. response#end never gets called) unless staleConnectionTimeout kicks in
- however, if response#end does get called, we should write a DefaultHttpChunk with 0 byte to the channel to signal the browser that streaming is over and then close the channel
attempt to fix tests for Travis
- replace HttpCookie.parse with netty CookieDecoder for jdk6 compatibility
- increase wait time for timing dependent tests so a slower CI server won't time out
