Mostly-mechanical additions: - Log constructions&destructions, usually by just inheriting from DecoderDoctorLifeLogger, otherwise with explicit log commands (for internal classes for which DecoderDoctorTraits can't be specialized), - Log links between most objects, e.g.: Media element -> decoder -> state machine -> reader -> demuxer -> resource, etc. And logging some important properties and events (JS events, duration change, frames being decoded, etc.) More will be added later on, from just converting MOZ_LOGs, and as needed.
