This is in response to an issue that's affecting the new app
update doorhangers on OSX, where the problem is more obvious.
On OSX, the panel styling makes it so that the doorhanger
overflows the window a little bit. This is fine until you enter
fullscreen with ctrl+command+F. At this point, the doorhanger
should come back onto the screen and the arrow should be rooted
to its anchor element (in our case the hamburger menu icon), but
instead it lags and the panel is not adjusted right away. This
is because right after the window is resized, which ends up
calling SetPopupPosition with aIsMove == false, SetPopupPosition
is called again from CheckForAnchorChange with aIsMove set to
true. There could be other solutions to this particular problem,
but since the aIsMove boolean is intended to limit the visual
noise when moving a window between screens, it seemed appropriate
for it to only prevent sliding or flipping if the panel isn't
already slid or flipped.
There was another issue affecting specifically the arrow, where
the logic for notifying observers of a positioning change in the
panel doesn't account for changes only to the position of the
anchor rect. This change adds tracking of that and sets aNotify
to true when called from ReflowFinished, since this is where
the position of the anchor element relative to the window can
need to change, even when the screen position of the panel rect
doesn't change.

There are several behaviors that we only need to apply to popups which are
known to contain remote content. And since those behaviors can cause issues
elsewhere, we need to be able to identify popups which should contain remote
content, and treat them specially, where appropriate.

The relevant frame classes are:
SubDocumentFrame
ListControlFrame (only when used for (non-e10s?) comboboxes)
PluginFrame
ViewportFrame
MenuPopupFrame
The view is now created in the frame's Init() method, except for
ViewportFrame which has its view assigned by the frame constructor
via a SetView() call.

Delete the "or 0 for no movement in that direction" from the CanAdjustEdges
document in nsMenuPopupFrame.h because the only caller in nsResizerFrame.cpp
never passes 0 to it.

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.

During reflow our frame, or any ancestors, may not yet be placed at their final position. So calculating the screen position of our popup during our reflow could produce incorrect results.
Instead post a reflow callback to do it after reflow is finished.
