Experience shows that we do not have enough profiler labels to make
BHR hang reports meaningful. This patch adds enough labels to let us
exploit hang reports matching the 25 topmost chrome hangs.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This alters nsIWebBrowserPersistable so that startPersistence takes an
outerWindowID. This allows us to target a particular subframe from
beneath an nsFrameLoader, which is useful when attempting to Save
Frame As a remote browser.
We send a pagehide event during swapping docshell frame loaders, and
before this patch we would not be able to differentiate this event with
the one that we send when navigating away from a page, so we would
incorrectly dispatch an audio-playback notification indicating that
audio playback has stopped. This patch adds a flag to the root docshell
when the frame loader swapping is in progress and disables the above
behavior when that flag is set.
The high-level overview is that the parts of nsWebBrowserPersist which
access the DOM have been factored out (as WebBrowserPersistLocalDocument)
and abstracted (nsIWebBrowserPersistDocument) such that they can be
implemented in the cross-process case using IPC.
Don't rely on MaybeCreateDocShell to set mRemoteFrame so we don't have
to call MaybeCreateDocShell in weird places. Instead we set mRemoteFrame
early in the nsFrameLoader constructor. This should still allow us to
switch default remoteness dynamically.
