only send if sendQueue is small
Remove stream helper complexity.

On master (0.0.17) these stream helpers were removed. They
    do not belong in this library and create weight and
    complexity.

Remove timeout feature and replace with unref().

The EphemeralSocket had a timeout feature build into it
    so that the statsd client doesn't keep a CLI program open.

This was implemented in a complicated way with timers, I've
    removed that complexity and replaced it with an unref() call.

Reset _writePos to zero.

This is a bug, we forgot to reset writePos
unref interval in packet-queue

The previous version of statsd-client would not keep
    a process open. This new version does.

To keep back compat we need to ensure that the statsd-client
    does not keep the process open.
