Fix race condition in upstreamConn.Close
upstreamConn.closed was a bool accessed from different goroutines. Use
the same pattern as downstreamConn instead.

Nuke user.lock
Split user.register into two functions, one to make sure the user is
authenticated, the other to send our current state. This allows to get
rid of data races by doing the second part in the user goroutine.

Add eventDownstreamDisconnected
This should remove the need for protecting user.downstreamConns with a
mutex.

Add eventDownstreamConnected
In a later commit, we'll be able to move part of downstreamConn.register
into the user goroutine to prevent races.

Introduce a user.events channel
This allows to easily add new events, and also guarantees ordering
between different event types.

Move upstreamConn.ring to network
This handles upstream disconnection and re-connection better.

Per-user dispatcher goroutine
This allows message handlers to read upstream/downstream connection
information without causing any race condition.
