1. This requires exposing radiogroup's focusedItem property to C++.
Unfortunately, there's no existing equivalent in nsIDOMXULSelectControlItemElement.
radiogroup is the only element that needs this, so a new interface has been created for it.
2. Accessibility uses focusedItem instead of selectedItem when setting focus.
3. When an item is focused, accessibility needs to be notified.
This is done using a DOMMenuItemActive event.

Now, nobody requires nsIContentIterator interface. So, we can get rid of it.
Unfortunately, there is no macro to keep the inherited class,
ContentSubtreeIterator, in the cycle collection to make it keep managing
ContentSubtreeIterator::mRange without nsISupports interface. Therefore, this
patch moves it into ContentIteratorBase temporarily. Anyway, the following
patch makes those classes not refcountable. At that time, this issue will be
fixed.

After landing bug 1517241, some lines in Document.cpp and Element.cpp depend on
`using namespace mozilla` and `using namespace mozilla::dom` of *different*
cpp files. Therefore, when you rename some cpp files in dom/base, you'll
hit compile error.
This patch fixes the dependency with moving some classes into mozilla namespace
and adding |mozilla::| or |dom::| to a couple of lines.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This needs to add a few of includes in other places which were relying on the
massive (now gone) list in nsDocument.h.
I also needed to move an AnimationTimeline destructor out of line because it
relied on dom::Animation being defined, yet Animation.h includes
AnimationTimeline.h, so include hell.

This patch moves all UA Widget calls to helper functions in Element.cpp. The helper function AttachAndSetUAShadowRoot sets the shadow root in a runnable, so that it is in the same order of NotifyUAWidget* runnables.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

When fingerprinting resistance is enabled, content should only view the
pointer capture events from the spoofed interface. In order to do so,
first, we need to restrict content to only set or release pointer capture
for only the spoofed pointer id. Second, we have to map other interfaces
into the spoofed one for pointer capture events.

As expected, this is specific to the UA widget stuff.
What's going on here is that given we don't clear out the host when unattaching
the shadow tree, mutating that shadow tree still notifies all the way up to the
document, and that gets all the other code confused, thinking that the node is
connected.
Indeed, the first assertion that fails when loading that test-case in a debug
build is:
https://searchfox.org/mozilla-central/rev/17f55aee76b7c4610a974cffd3453454e0c8de7b/dom/base/nsNodeUtils.cpp#93
This seems the best fix to avoid confusion. Also clear the mutation observer,
to completely forget about the host.
Chrome code dealing with UA widgets needs to be careful, but I think this is
safe. All the code that assumes that GetHost() doesn't return null is in code
dealing with connected shadow trees only (style system / layout), or in
mutation observer notifications from the host.

This should be more generic than hardcoding the tags, and be enough for our
chrome to avoid regressions as they migrate more stuff to CE, avoiding calling
