Revert "engine.io: added middleware attachment possibility (eg: for express)"

This reverts commit 7b3243dbeaa611751780617158a577b006d477ce.
engine.io: deprecated `resource`
engine.io: cleanup
socket: added `Socket#write`
engine.io: style
socket: emit `data` event (synonym with `message`)
Fixed packet send callback design issue

There were two issues here.
1. When Socket.send called with or without callback alternately,
   the trigger order is incorrect.
2. The 'drain' event from transport is one per packet for transports
   supporting framing like websocket and is all in one for those without
   framing like polling.
