This prevents a brief flash of unstyled tab content that can be noticed especially
in debug builds.
What happens currently is that we first append child content into the tab
upon connection, then we do attribute inheritance which sets the relevant
styling properties.
With this change we first set up the child content and attributes _before_ appending
the tab into the DOM, so that it's ready to render after being appended.

The tool tip for a browser tab exposes information such as the process ids (on Nightly) and the container tab name.
It appears when a user mouses over the tab, but this isn't really accessible to screen reader users.
Ideally, we'd expose this information as the accessible description for all browser tabs.
However, doing this for all tabs and keeping it up to date is rather difficult and potentially expensive.
Instead, just expose this description for a tab when it gets focus; i.e. the user has to focus the tab bar to access it.
To enable this, XUL tab elements now fire an AriaFocus event on the ARIA focused tab when the ariaFocusedItem property is set.

The conversion for "regular" <tabs> elements is straightforward, most of
the work here is to support the tab strip (the <tabs> element with the id
"tabbrowser-tabs"). The markup needed for the tab strip moves directly
into browser.xhtml and the construction/teardown logic is now explicitly
driven from gBrowser. There are many more little tweaks too numerous to
enumerate.

A bunch of existing code assumes that <tab> elements are the immediate
and only children of a <tabs> element, and uses dom apis to traverse
relationships between these elements. To simplify conversion of <tabs>
to a custom element (and hopefully improve readability a bit at the same
time!), introduce new apis:
On <tab>
this.parentNode -> this.container
this.nextElementSibling -> this.container.findNextTab(...)
this.previousElementSibiling -> this.container.findNextTab(...)
On <tabs>
this.children -> this.allTabs

Right now there's some duplicated code with the focus manager and the
DOMWindowFocus event.
Android didn't handle the new framefocusrequested event, so the test-cases in
bug 416771 still didn't work there.
I think using the focus manager codepath everywhere is preferable. I confirmed
manually that the stuff that sent DOMWindowFocus events still works as expected
with this patch (i.e., switching to the right tab when you click on a
notification, etc.).
This fixes it so that it works in Fennec, and it sends the focus events right in
GeckoView Example (i.e., we get here[1] properly).
The snippet that Snorp provided on IRC to implement the "bring activity to
front" stuff (`startActivity(getIntent())`) didn't actually work for me, but I
confirmed that the right message is sent when the focus is requested, and that
we get there.

Previously the `WebNavigationChild` would keep track of when triggering its
`nsIWebNavigation`, `goForward`, `goBack`, `gotoIndex`, and `loadURI` methods.
It's `nsIWebNavigation` instance is always an `nsIDocShell` and as part of
porting `OnStateChange` and `OnLocationChange` events from
`WebProgressChild`/`RemoteWebProgress` to `BrowserChild`/`BrowserParent`, this
informations needs to be available from the `BrowserChild`. As it stands, it is
currently an expando property on the `WebProgressChild`.
Instead of introducing yet another XPCOM interface for the WebProgressChild, we
now store this information directly on the `nsDocShell`. Furthermore, instead
of having the `WebNavigationChild` manage this part of the `nsDocShell`'s
state, we can have the `nsDocShell` manage this state itself so it is always
consistent.
