Add upstreamConn.SendMessage 
Allows us to change upstreamConn implementation details without updating
the whole codebase.

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

Abbreviate {upstream,downstream}Conn with uc and dc 
This makes it clearer than just `c` when we manipulate both kinds at the
same time.

Simon Ser 0cf731aeab
Don't write to downstreamConn.messages directly 
Use a helper function instead. This will allow us to change
downstreamConn implementation details without having to update the whole
codebase.
