With these changes, XBL just runs in the window scope of whatever document it's
attached to. Since (outside of tests and "remote XUL") we no longer attach XBL
to web documents, this is fine. And "remote XUL" already ran without the XBL
scope.
Native anonymous content, which used to be placed in the XBL scope to hide it
from the page, is now placed in the unprivileged junk scope, so it stays hidden
from the page.
dom/xbl/test/test_bug944407.xul is being removed because we are changing the
behavior it's trying to test for. Since we now always put the XBL in the same
scope as the page, script is enabled for the XBL if and only if it's enabled for
the page.
dom/base/test/test_bug419527.xhtml, dom/events/test/test_bug391568.xhtml,
dom/xbl/test/test_bug1086996.xhtml are being switched to a chrome test because
otherwise the XBL can't see the getAnonymousNodes method.
All the XBL bits are being removed from test_interfaces because we no longer
have a separate XBL scope to test the behavior of.
js/xpconnect/tests/mochitest/test_nac.xhtml is being removed because XBL no
longer has access to NAC unless the page it's attached to does too, so the test
doesn't really make sense.
layout/xul/test/test_bug1197913.xul is being switched to a chrome test because
its XUL elements use bindings that rely on APIs that are not exposed to normal
web content.
layout/reftests/bugs/495385-2f.xhtml is being removed because I can't think of
a sane way to test that in the new world, short of running the reftest as
chrome. And it doesn't seem worthwhile to look for a way to do that.
dom/xbl/test/test_bug1098628_throw_from_construct.xhtml now needs to
expectUncaughtException(), because the exception is now being thrown in Window
scope.
dom/xbl/test/test_bug1359859.xhtml needs to expectUncaughtException() as needed
and not use XPCNativeWrapper (which it doesn't need to anyway now).
dom/xbl/test/test_bug389322.xhtml, dom/xbl/test/test_bug400705.xhtml,
dom/xbl/test/test_bug401907.xhtml, dom/xbl/test/test_bug403162.xhtml,
dom/xbl/test/test_bug526178.xhtml, dom/xbl/test/test_bug639338.xhtml don't need
to use XPCNativeWrapper anymore.
dom/xbl/test/test_bug821850.html is being removed because it exists only to test XBL scopes.
dom/xbl/test/file_bug950909.xml is being changed to work without a separate XBL
scope (though whether the test still makes sense at that point is a bit questionable).

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.

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.
Add a WindowProxyHolder type and generate binding code that takes or returns it whenever
the WebIDL refers to the WindowProxy type. This patch just makes the WindowProxyHolder
hold a strong reference to a nsPIDOMWindowOuter.

This is a straight backout of (in that order) bug 1505468, bug 1503664, bug
1501479, bug 1499150, bug 1496805, and the second part of bug 1493849. The
first part of bug 1493849 was a backout of earlier instrumentation, and that
should stay.
At this point we know we're hitting OOM inside the JS engine while trying to
define properties on Document.prototype, so all this MOZ_CRASH instrumentation
is no longer needed.
This is a best effort attempt at ensuring that the adverse impact of
reformatting the entire tree over the comments would be minimal. I've used a
combination of strategies including disabling of formatting, some manual
formatting and some changes to formatting to work around some clang-format
limitations.

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.

The spec algorithms have a step that throws NotFoundError in between steps that
throw HierarchyRequestError. We can't really implement that with our current
setup.
This changeset does not change observable behavior.
Various places in dom/ use the pattern:
already_AddRefed<NodeInfo> ni = ...;
which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason. To fix our static analysis code, we need to
eliminate instances of the above pattern.
Unfortunately, eliminating this pattern requires restructuring how Nodes
are created. Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`. We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.
While trying to repro bug 1484293 I noticed that this assertion failed:
https://searchfox.org/mozilla-central/rev/ef8b3886cb173d5534b954b6fb7eb2d94a9473d0/dom/base/ShadowRoot.cpp#160
(during unlink, while unbinding the kids)
We rely on GetComposedDoc returning the right thing during unbind to cleanup
some stuff (see bug 1473637 for example), so it should probably be correct all
the time, regardless of whether something is unlinked or not.
Also this makes GetComposedDoc() much faster, which is nice too, since we call
it somewhat often.
I removed NodeHasRelevantHoverRules, since it's unused (was used by the old
style system).
I moved the SetIsConnected(false) call for the shadow root to before unbinding
the kids for consistency with what Element does with the uncomposed doc flag,
now that the children's connectedness doesn't depend on the shadow root's.

The DOM elements within the UA Widget Shadow DOM should have its reflectors in
the UA Widget Scope. This is done by calling nsINode::IsInUAWidget() which
would check its containing shadow and its UA Widget bit.
To prevent JS access of the DOM element before it is in the
UA Widget Shadom DOM tree, various DOM methods are set to inaccessible to
UA Widget script. It would need to use the two special methods in ShadowRoot
instead to insert the DOM directly into the shadow tree.

Mostly automatic via sed. Only parts which I touched manually (apart from a
couple ones where I fixed indentation or which had mispelled arguments) are the
callers. I may have removed a couple redundant `virtual` keywords as well when
I started to do it manually, I can revert those if wanted.
Most of them are just removing the argument, but in Element.cpp I also added an
assertion for GetBindingParent when binding the ShadowRoot's kids (the binding
parent is set from the ShadowRoot constructor, and I don't think we bind a
shadow tree during unlink or what not which could cause a behavior difference).

It's currently only accessible on XULDocument and XULElement, but that makes porting existing

this can be easily moved and exposed in chrome contexts.

Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need
to match document rules, see the linked SVGWG issues.
But blocks_ancestor_combinators goes away, which is nice since it's on a very
hot path.
Test Plan: WPT for style invalidation, covered by existing tests otherwise.
