Extension panels contain embedded documents; i.e. a <browser> element.
We want users to be able to tab to these and we want them to be focused automatically if a subview is opened from the keyboard, so treat them as tabbable.
However, once an embedded document is focused, we can't manage keyboard navigation inside it, so don't try.
Previously, we tried, which meant keys were overridden even though they didn't do anything, breaking keyboard navigation in extensions altogether.

As of this change, instances of xul <button> use a custom element.
The button-base xbl binding remains for now, since it is still used
by toolbarbutton, it will be removed soon.

Previously, this code cached a list of controls on first use and used that for navigation.
This refactor addresses several issues:
1. There is now a separate focus order for tab/shift+tab and down/up arrows.
This allows menulists, textboxes, etc. which use the arrow keys themselves to be focused with tab, but skipped with the arrows.
This means the user won't fall into these controls when using the up/down arrow keys and be confused by the subsequent arrowing behaviour.
2. When a menulist, textbox, etc. is focused, the arrow keys, space and enter are now passed to the control.
This is a better fix for handling of the arrow keys by menulists (bug 1522092).
It also fixes left arrow in a textarea moving to the previous view instead of moving the caret (bug 1489874).
3. This improves handling of dynamic updates to the panel.
For example, elements that are initially disabled and enabled later will be navigable.
This is because the next element is determined dynamically by the TreeWalker, rather than using a cached list.
4. The interim fix for bug 1522092 disabled PanelMultiView keyboard navigation.
This caused some regressions, including arrow keys/activation on the Site Identity Report a Problem link (bug 1539976) and some controls not being navigable if the Site Identity panel is opened using the mouse (bug 1539984).
With the above fixes, we can now re-enable PanelMultiView keyboard navigation in the Site identity panel and thus fix these regressions.
5. Previously, PanelMultiView keyboard navigation was disabled in the main toolbar overflow menu.
This is because the search box can be added to the overflow menu, which previously caused problems for the arrow keys.
With the above fixes, we can now safely enable PanelMultiView keyboard navigation in the overflow menu.
6. PanelMultiView keyboard tests have been added.
Previously, we relied on tests specific to various panels to exercise this functionality.

Moved tab context menu out of browser.dtd to browser.xul except for sendPageToDevice, sendLinkToDevice, moveTabOptions, moveSelectedTabOptions, undoCloseTab. Not sure if tabbrowser.js and tabbrowser.xul are working as intended.

waitForCondition usage in the browser_947914_button_addons.js test file can be replaced by the TestUtils.waitForCondition utility function.
> The function was replaced. There was only one occurance in this file (browser_947914_button_addons.js), but may exists in other ones.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

Previously, we had specific code to do this for the "View site information" button (#identity-box) when activated via the keyboard.
To work well for keyboard and screen reader users, all such popups (e.g. Firefox menu, Page Actions, etc.) should do this.
These are all based on panelMultiView.
The arguments passed to PanelMultiView.openPopup can include the event which triggered the popup.
We now use this to detect keypress events and focus the first item in the panel in that case.
