server/main_channel: support multiple clients

The main channel deals with connecting new clients, announcing mouse mode
changes, and the agent channel. The implementation is currently done without
any changes to the protocol, so everything has to be either broadcast or
to a specific client.

 channels list - specific client
 mouse mode - broadcast
 agent - broadcast
 notify - broadcast (should have two modes, and use the appropriate)

Notable TODOs:
 * migration testing
 * agent tokens are wrongly sent (or did I fix that? check)
