e9f8b0e76f Remove Valve protocol checks and set select() timeout to 1.5 seconds 
Use the same method for handling multipacket responses across all servers.

c607925b2e Implement select() loop to receive all incoming packets: 
Send a "multipacket guard" - an empty packet with an invalid 'cmd' field
and a unique packet ID to trigger a reply from the server once the previous
command's reply has been fully sent.

Valve returns an empty payload, while Minecraft includes an error message in the payload.

This workaround ensures that all packets related to the last valid command
are received from the server, avoiding the need to wait for the select() timeout.
