• JMUX multiplexing protocol implementation for jetsocat and gateway server
• Improve various startup validations and diagnostics
• Support for generic plain TCP forwarding (e.g.: raw SSH forwarding)
  This requires sending a preconnection PDU containing an appropriate token
• Duplicate root HTTP endpoints under /jet (this help simplifying routing configurations)
• Support for alternative hosts to try in successive order
• Token reuse mitigation based on IP address (RDP protocol requires to connect multiple times
  and previously used token can't just be rejected)
