net.server: Add a predrain callaback just before writes
Allows sneaking in things in the write buffer just before it's sent to the network stack. For example ack requests, compression flushes or other things that make sense to send after stanzas or other things. This ensures any additional trailing data sent is included in the same write, and possibly the same TCP packet. Other methods used such as timers or nextTick might not have the same effect as it depends on scheduling.
