This is made possible by a new workaround for a layout issue with panels that would prevent the main view from being displayed.

This also adds a new "active" property that can be used by regression tests to determine whether they should still wait for the ViewShown event.

window.promiseDocumentFlushed will call a callback as soon as a style or layout
flush is not required for the document (which might be immediately). This is a
new ChromeOnly API introduced in an earlier patch in this series.
This patch also removes the now-unneeded BrowserUtils.promiseLayoutFlushed and
BrowserUtils.promiseReflowed methods and infrastructure.

This stops redundant ViewHiding and late ViewShown events from being dispatched when the panel is closed during a ViewShowing event or a transition, and stops dispatching ViewHiding events when a view becomes invisible but is still open.
The panelMultiView property on "panelview" nodes is now set to null when the view is closed, indicating that the view can be immediately reused in a different panel. The Places view had to be updated so it doesn't rely on this property during the PanelMultiViewHidden event.

The ViewHiding event is now dispatched consistently, regardless of whether the ViewShowing event is canceled or the panel is closed during the event. This is done by a new _openView helper, while the logic that is specific to each of the showMainView, showSubView, and goBack functions has been moved out of the _showView function.

This allows the openViews array to reflect the state of the navigation more accurately, paving the way for further simplification of the code. The showSubView function will now fail early when it's called with a view that is already open, so the rest of the code doesn't have to take this case into consideration.

The ViewShowing event is now called earlier and unconditionally, since we don't set the "current" attribute and call showMainView while the panel is closing anymore.
It is already the case that the ViewShowing event handlers don't depend on the "current" property, so we don't need to keep track of it before ViewShown events are dispatched.

The showSubView public method now aligns with its callers and doesn't return a Promise anymore. The showMainView method still returns a Promise because at the moment it is used externally for asynchronous cleanup.

This allows the ViewShowing event for the main view to prevent the panel from opening. It also avoids setting up the main view if the panel is not opened.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
