QUIC: distinguish reserved transport parameters in logging. 18.1. Reserved Transport Parameters Transport parameters with an identifier of the form "31 * N + 27" for integer values of N are reserved to exercise the requirement that unknown transport parameters be ignored. These transport parameters have no semantics, and can carry arbitrary values.
