Subject: Supports going through multiple Socks proxies

This commit also reworks the switch_protocol command.
The `P | {P, Opts}` type is used here as well. This
allows us to remove the code specific to Websocket.

In addition a few new protocol functions allow us
to declare what's the name of the options key for
the protocol and what the capabilities are with
regard to keepalive.
