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
