* `clip` option is always passed from the client code
* with this change, we can no longer capture screenshot of a blinking
caret; the browser-side API doesn't have this capability.
This roll:
- NetworkObserver now uses the `remote's` ChannelEventSink layer to
subscribe to redirects.
- Wheel events now must be dispatched from browser process.
- There's a new API for console messages
- The old methods to wait for search service and addon manager no longer
work; speculatively remove them since neither `remote` nor
`marionette` have anything like this.

When firefox is automated + interacted with manually, input composition
might get stolen from Text Input Processor.
Re-requiring TIP every time seems to fix this.

After this roll, we no longer require our custom `onFrameLocationChanged` instrumentation
since gecko now fixed the `NOTIFY_LOCATION` behavior so that it works
for same-document navigations inside iframes.
Somehow, we get WebProgress state changes when worker is loaded
with a blob url. This messes up frame navigation detection.
Luckily, it's easy to filter out non-document state changes.
As Joel noticed recently, MessageManager in firefox doesn't guarantee
message delivery if the opposite end hasn't been initialized yet. In
this case, message will be silently dropped on the ground.
To fix this, we establish a handshake in SimpleChannel to make sure that
both ends are initialized, end buffer outgoing messages until this
happens.
Drive-by: serialize dialog events to only deliver *after* the
`Page.ready` protocol event. Otherwise, we deliver dialog events to the
unreported page.
Using WebProgressListener events works in all cases. Currently
used `pageshow` event will stop being emitted in future when loading
was stopped with `window.stop()` api.

This patch:
- moves `SimpleChannel` to synchronously dispatch buffered commands
instead of a `await Promise.resolve()` hack
- moves dialog & screencast handling from `PageHandler` to
`TargetManager`. This leaves `PageHandler` to be concerned solely about
protocol.
- removes `attach` and `detach` methods for worker channels: since
channels are buffering messages until the namespace registers, there's
no chance to loose any events.
- slightly simplifies `PageNetwork` class: it's lifetime is now
identical to the lifetime of the associated `PageTarget`, so a lot can
be simplified later on.
