Fix capitalization of 'id' 
Following the Go project source code guidelines, id is an abbreviation
and must typically be written as id or ID, not Id.

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).

Fix wrong handling of members parameter of RPL_NAMREPLY 
Some servers (namely UnrealIRCd) wrongly add a trailing space to the
members parameters of the RPL_NAMREPLY command, which was not handled
correctly.

Adding a trailing space is not legal wrt the IRC specs, but since
UnrealIRCd does it and is in wide use today, we have to work around it.

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.

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
