Fix race between queueing redirect and closing connection, close #46.

What's happening here (as far as I can tell) is that the mtENDPOINTS
packet generated during a redirect is being dropped. The sequence of
events is:

- generate the packet
- post a send(packet) to the peer's strand, queueing a send
  event for later
- set m_detaching=true
- call async_shutdown() on the socket, nothing sent on the
  wire past this point
- peer's strand then dispatches the send()
- sees m_detaching==true and drops packet

The fix is as follows:

1. detach() is split in two: detach() itself just posts a call to
   drainAndClose() to the strand. m_detaching is set in drainAndClose(),
   which is made idempotent.

2. sendPacket() still checks m_detaching and drops a packet if
   it's true; but otherwise it always posts a call to the strand.
   sendPacketForce renamed queueOrWritePacket

These two points mean that a synchronous call sequence like

 { send(); detach(); }

in the caller definitely results in two events posted to the strand,
in order. The send will make it through the test of m_detaching and
get posted, because m_detaching won't have been set yet. Then further:

3. queueOrWritePacket() is modified to queue packets to mSendQ if there's
   a write in progress (this formerly raced on the socket and the
   queue, as far as I can tell).

4. drainAndClose() considers queue-not-empty or write-in-progress as
   "work pending" and returns early, doesn't fully close the socket.

5. handleWrite re-posts queueOrWritePacket() or drainAndClose() based
   on the presence of work in mSendQ and the setting of m_detaching,
   respectively.

These three points mean that the strand gets drained into the socket
if possible, the queue if necessary, with handleWrite reposting work
that got queued every time a write finishes.
