QUIC: fixed probe-congestion deadlock. When probe timeout expired while congestion window was exhausted, probe PINGs could not be sent. As a result, lost packets could not be declared lost and congestion window could not be freed for new packets. This deadlock continued until connection idle timeout expiration. Now PINGs are sent separately from the frame queue without congestion control, as specified by RFC 9002, Section 7: An endpoint MUST NOT send a packet if it would cause bytes_in_flight (see Appendix B.2) to be larger than the congestion window, unless the packet is sent on a PTO timer expiration (see Section 6.2) or when entering recovery (see Section 7.3.2).
