See bug 1565197.

This bug is about focusing on DebuggerServer.connectToFrame:
And see from there if we can replace all message manager usages that unroll from this without refactoring the DevTools universe completely.

I tend to believe that setupInParent should be automagically working without much specifics.

Note that this work should ignore the fact that we could have remoted iframes.
We can pass allFrame: false to ChromeUtils.registerWindowActor.
The focus here should be to convert to the new API sooner than later.

I think that using this API would help support process switching of tabs.
This is a side effect of Fission, where there isn't necessarily remoted iframes.
When you navigate from one URL to another, the tab may load the two documents in distinct process and we would have to support that nicely. For now, the toolbox closes and reopen...

I would like to do some cleanup in main.js
After this initial split I would also like to extract the connectToFrame/connectToWorker blocks
But before I go too deep into this I'd like to check if this seems ok with you and if it doesn't conflict
with too many other inflight patches.

Tentatively moving all bugs whose summaries mention "Fission" (or other Fission-related keywords) but are not assigned to a Fission Milestone to the "?" triage milestone.

Making DevTools Fission-compatible is a prerequisite for enabling Fission in Nightly (M6).
