1649495 - Add pref to enable QUIC qlog logging

Status: RESOLVED FIXED

(Core :: Networking: HTTP, enhancement, P2)

Description

[Andy Grover [:grover]]

Qlog is a cross-implementation JSON-based logging standard for QUIC/H3 connection traces. Being able to analyze protocol traces from actual in-browser Neqo usage will greatly help fixing bugs.

Neqo has qlog support, but enabling it requires giving it a directory to place the per-connection trace files in.
