It was needed presumably because XBL could override the tag name and what not.
But I removed that capability for elements other than XUL elements, so we can
just poke at the content directly.

This change also renames several related functions, as well as fields,
and the header is moved into EXPORTS.mozilla given it is defined under
mozilla namespace.

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).

This builds on bug 1428676 and introduces StyleAppearance, which replaces the
NS_THEME_* constants.
Really sorry for the size of the patch.
There's a non-trivial change in the gtk theme, which I submitted separately as
bug 1478385.

It's not needed anymore, since we tag the pseudo-elements at creation time for
styling.

We verify the flattened tree is correct in VerifyFlatTree (in RestyleManager),
plus the post-condition still holds of course.

Using references helps to see when stuff can and cannot be null.
I removed useless aTag / aNamespaceId arguments which are useless now that XBL
can't override them (bug 1450617), so FindXULData is the only one that keeps
them alive.
Also, I took the liberty of renaming a few fooComputedStyle variables to just
fooStyle, and clarify naming in some pseudo-element-related functions to say
originating element (the spec term) and avoid confusing it with the generated
_moz_generated_content_before / _moz_generated_content_after element.
Note that this is a partial state, more stuff will come in the future.

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.

This way we reuse the same machinery everywhere for the content property.
The only difference is that we need to look at the parent style for content
instead of just our style, and at a given index.
Again, this is fine because changing content reframes, so no chance to mess up.
This allows the generated content stuff to not implement nsImageLoadingContent
and all that stuff, nor deal with events, which makes it much simpler IMO.
Now it just tracks an index. We may not even need for it to be an HTML element,
but I've kept that for now.
I added a crashtest that used to crash because of the bogus
nsCSSFrameConstructor code which trusted the node name without checking it was
native anonymous.

Dynamic changes are handled correctly because content property changes already
cause a reframe.
This implements the same bits as Blink / WebKit do (single content item which is
an image, otherwise gets ignored), except for the edge cases where you use this
on an image.
In order to handle the edge cases right, we completely isolate the
nsImageLoadingContent usage based on `mKind`.
Blink's and WebKit's behavior there makes no sense and it's erratic, what I
implemented is consistent (we apply to images as long as they don't generate a
box, and we don't look at alt text or broken icons), though I'll update to
whatever the WG decides in https://github.com/w3c/csswg-drafts/issues/2831 /
https://github.com/w3c/csswg-drafts/issues/2832.
I don't think it matters in terms of web compat in any case.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.
MozReview-Commit-ID: 5UQVHElSpCr
The whitespace optimization code only knows about the light tree.
It's not a great idea to try to put flattened tree children of a slot through
there, since the children may not be assigned to the same slot, or to any slot
(in which case we crash).
We should probably rename XBLInvolved to ShadowDOMOrXBLInvolved too, I guess.
Note that the ShadowRoot case already sets the bit on Init().

The DoMouseClick helper is also removed because no other caller can now pass a null aEvent. Other MouseClicked implementations are also updated since aEvent cannot be null, which was already the case.

This was done automatically replacing:
s/mozilla::Move/std::move/

In this case we have a shadow hoot with display: contents, with no children.
Those children wouldn't be flattened tree children of the shadow host.
Instead of using the last light dom child and seek to it, use
FlattenedChildIterator's reverse iteration.

Currently, NAC always inherits from the closest non-NAC ancestor element,
regardless of whether it is for an element-backed pseudo or not.
This patch changes the inheritance so that for element-backed pseudos, we
inherit from the closest native anonymous root's parent, and for other NAC we
inherit from the parent.
This prevents the following two issues and allows us to remove the
NODE_IS_NATIVE_ANONYMOUS flag:
* Avoiding inheriting from the non-NAC ancestor in XBL bindings bound to NAC.
- This is no longer a problem since we apply the rule only if we're a
pseudo-element, and all pseudo-elements are in native anonymous subtrees.
- This also allows to remove the hack that propagates the
NODE_IS_NATIVE_ANONYMOUS flag from the ::cue pseudo-element from
BindToTree.
* Inheriting from the wrong thing if we're a nested NAC subtree.
- We no longer look past our NAC subtree, with the exception of
::-moz-number-text's pseudo-elements, for which we do want to propagate
::placeholder to.
A few rules from forms.css have been modified because they're useless or needed
to propagate stuff to the anonymous form control in input[type="number"] which
previously inherited from the input itself.

Second test-case is because I initially made this code work with
display: contents. But then realised that display: contents meant allowing
Shadow DOM in there, which I don't really want to deal with right now.

After bug 1303605 we can assert this, since we make sure all children have the
same flattened tree parent, and thus insertion point.
