...instead of forwarding to the sheet like HTMLStyleElement does.
I've proposed this behavior in:
https://github.com/whatwg/html/issues/3840#issuecomment-480894419
I think this is one of the sane behaviors we can have, what Blink / WebKit do
makes no sense to me.
Alternative potentially-sane behavior is making the initial value of the
stylesheet's disabled bit the same as the content attribute, and both reflect
and forward the attribute from the setter.
That means that setAttribute does something different than setting `disabled`,
which means that you can get into all sorts of funny states when reloading the
sheet... So I rather not do that.

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.
Bug 1483882 removed the line that used to remove the SHADOW_TREE bit during
unbind. I missed this caller which still assumed that `IsInShadowTree() ->
GetContainingShadow()`.
That means that before that patch it was going through
nsIDocument::RemoveStyleSheet, which looks pretty wrong to me.
Fix it so that we don't remove the stylesheet (we weren't doing it before
anyway), but we don't crash.

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 patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

Now that BeginUpdate is useless for the UPDATE_STYLE case, we don't need the
update mechanism at all. Just ensure that ApplicableStylesChanged is called on
the pres shell via the relevant RuleChanged, etc. notifications.
There's a big hidden gotcha here. nsIDocument::BeginUpdate does put a script
blocker on the stack for these updates. However it's not needed, since no script
can run during these notifications (only the stylesheet events we post for
devtools, but those use AsyncEventDispatcher and PostDOMEvents, so they don't
try to run immediately).
nsIDocument::BeginUpdate also does XBL binding attached queue stuff, but we
can't change bindings during these notifications anyway, so it also doesn't
matter.

I've kept the nsAutoStrings in the StyleSheetInfo class on the hopes that the
compiler does RVO, but if it doesn't I can remove I guess.

After discussing with Olli there isn't any kind of severe problem out of this.
Shadow subtrees will be disconnected just like the rest, and they shouldn't
assume that the document hasn't been disconnected first.

Returning the same type and UpdateStyleSheet.
This hopefully helps seeing how the data flows between the methods, instead of
the messy bits we had before.

It would be convenient to get nsPresContext from nsIDocument.

This change captures the subject principal when a scripted caller sets the
textContent or innerHTML property of a <style> node, and uses it as the
triggering principal for the resulting stylesheet.
If the node contents are modified in any way other than through textContent or
innerHTML, the triggering principal is forgotten (which is an intentional
design feature).
