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

Simon Ser 36ab6ece09
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.
