First part of refactoring constellation to support iframe navigation.

Browse source 
The history is now recorded per frame, but needs to be exposed in a followup PR.

Also fixes a race condition that occurs loading iframes under heavy CPU load.

This ensures that iframes never do a reflow / layout until they have a valid
window size set from their parent frame.
