Debugging QUIC with H2O and QLog

Debugging QUIC with H2O and QLogOne of the key qualities of a computer program is its debuggability. This is especially true for protocol implementations where interoperability with different implementations comes into play. In addition to testing for correctness, good debuggability also helps identify opportunities for performance tuning. This is crucial for QUIC, given how the protocol currently
