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.

Add KICK support
Downstream and upstream message handling are slightly different because
downstreams can send KICK messages with multiple channels or users,
while upstreams can only send KICK messages with one channel and one
user (according to the RFC).

Simplify error handling for downstream JOIN/PART
downstreamConnection.unmarshalEntity already returns an ircError of
command ERR_NOSUCHCHANNEL, so there's no need to explicitly return
another ircError of that type.

Route NAMES, WHO, WHOIS replies to the requesting downstream
Using labeled-response, the replies to several commands such as NAMES,
WHO, WHOIS can be routed back to a specific downstream, rather than
being broadcast to all downstreams.

For example, after this commit, if the server supports labeled-response,
if a downstream requests the NAMES or WHO or WHOIS of a channel, the
replies of the upstream will only be sent back to that downstream, and
the other downstreams won't receive these messages.

Add a server-unique id to each downstream
Adding a simple uint64 id to each downstream is preparatory work
for labeled-responses tags targeting a specific downstream.

Fix issues related to Ring
- RingConsumer is now used directly in the goroutine responsible for
  writing downstream messages. This allows the ring buffer not to be
  consumed on write error.
- RingConsumer now has a channel attached. This allows PRIVMSG messages
  to always use RingConsumer, instead of also directly pushing messages
  to all downstream connections.
- Multiple clients with the same history name are now supported.
- Ring is now protected by a mutex
