------- Additional Comments from Michael Schneider <michschn at google.com>
This proposed patch adds an webInspector.timeline API. It contains three event
sinks:
- onStarted: Listeners are notified when the backend starts collecting timeline
data.
- onStopped: Listeners are notified when the backend stops collecting timeline
data.
- onEventRecorded: Listeners are notified when a timeline record is collected.
The record is passed as first argument to the listener.

The start/stop is implicitly controlled if onEventRecorded listeners are
present.

For it to work, a TimelineManager was introduced to broadcast the events
received via InspectorBackend.registerDomainDispatcher("Timeline", ...). The
TimelinePanel now registers at the TimelineManager to receive events.
