Make the player proxy follow the Factorio handshake and route by version

Browse Source

The proxy now parses the full message header, so confirms and fragmented
ConnectionRequestReplyConfirm messages (which carry the mod list) are
forwarded intact, with the server request id patched into the first
fragment. It resends the connection request until the instance answers,
starts over when a client reconnects from the same socket (as Factorio
does after LuaPlayer::connect_to_server), answers pings from the server
browser and tells clients the same 508 byte max packet size Factorio
servers use.

Routing is decided by the new playerProxyRoute controller hook, which is
given the name and version of the player, then a dedicated port set with
instance.player_proxy_port, the instance the player was last on (taken
from the user's instance stats instead of a separate routing store), and
controller.player_proxy_default_instance_id.

The proxy is now off by default, as port 34197 is in the default
host.factorio_port_range. Leftovers of the per-instance proxy on hosts
are removed.
