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.
This allows us to send a sync fork request to the Nuwa process when we need one but there is no
spare process available. After an app is launched, the request to fork a spare process is still
handled asynchronously.

There are a variety of ways that the parent and child process ensure that
the child process exits quickly in opt builds, but for AddressSanitizer
builds we want to let the child process to run to completion, so that we
can get a LeakSanitizer report.
This requires adding some addition LSan suppressions, because running
LSan in child processes detects some new leaks.
We were returning a nullptr from AllocPRenderFrameParent in TabParent, which causes
a killhard abort in the child. We suspect this is occurring because the TabParent
is attempting to kick off drawing in a tab that's already closed (so there is no
frame loader, which means we can't create a PRenderFrameParent). So now, we return
a PRenderFrameParent* even if constructing it was unsuccessful, and the child
destroys it once it confirms that there is an invalid layer ID associated with
the RenderFrame.

When we pause the sampler in the parent, we should pause it in the child as well.
Similarly, when the parent resumes, the child should also resume.

The MobileViewportManager ("MVM") is responsible for setting the CSS viewport on
any of the following events:
- a page is painted for the first time (on the before-first-paint event)
- a meta-viewport tag is added (on the DOMMetaAdded event)
- the full-zoom is changed (on the FullZoomChanged event)
- if the window is resized (ResizeReflow gets called as part of normal layout
processing, and this will pick up a new CSS viewport from MVM)
If the CSS viewport changes or if it is the initial paint, the MVM additionally
calls SetResolutionAndScaleTo on the presShell to update the displayed zoom.
The APZ code in AsyncPanZoomController::NotifyLayersUpdated already has
corresponding code to accept this updated zoom when the CSS viewport changes.

We don't ever want to accept "private", "non-private", "remote" or "non-remote" from the
content process. We only let the parent decide when to open those types of windows.

The code that deals with the features is looking for char *, and we were going through
the hassle of converting that char * to a UTF16 string, and then back down to UTF8,
and then to char *. Really, we just need to send up a nsCString, which simplifies things.
