Attachment: Bug 1577723: Store BrowsingContext ID in dom::Location rather than DocShell weak reference. r=farre

Storing a DocShell rather than a BrowsingContext causes a number of problems
when dealing with cross-process navigations. The most immediate in this case
is that some cross-origin-allowed operations only work after a local-to-remote
navigation only until the original DocShell is destroyed, which causes
intermittent test failures.

It also means, though, that after a local-to-remote navigation, where the
DocShell has not been destroyed, attempts to read same-origin properties still
end up at the old DocShell, and as a result, lie about the current state of
the BrowsingContext.
