This reuses our existing undisplayed style generation, but in a
per-document rather than per-nsComputedDOMStyle object, which means that
we can avoid re-resolving styles of elements in display: none subtrees
much more often.
This brings the test-case in the bug to par with other browsers or
better, and is much simpler than the initial approach I tried back in
the day.

Instead, fix up the various content data structures when the stylesheet
is mutated. This makes reading a stylesheet not disable style sharing.

This should be both a memory and speed win for pages using a lot of
Shadow DOM.
In order to make the cache properly work we need to start keying media query
results on the actual StyleSheetContents, as that's what we share on Gecko, but
that should all be fine.

This reduces a lot the boilerplate that's needed in order to add simple binding
functions.
This starts using &Foo and Option<&Foo> instead, and as a result we need to
remove the servo_function_signatures test, which is a bit unfortunate.
I think it's worth though, this causes problems on some platforms (see bug
1534844), and messing up the functions signature is not something that I've ever
seen (other than bug 1308234, which already had all the FooBorrowed mess which
I'm removing).
Also, cbindgen understands references and Option<&Foo>, so it will be the way to
go in the future.
After this patch we can also remove HasSimpleFFI, but I've kept it for now since
I still use it in a few places, and this patch is quite big on its own.

We really only have two sets of prefs, one for chrome-like documents
(stuff in chrome docshells + chrome-origin images), and one for the rest.

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.
We force a repaint from ContentStateChangedInternal if visited links are
disabled, and that's observable. Let's cut it off as early as we can to avoid
timing attacks even when :visited is disabled.

This is necessary because we can't create GeckoStyleSheets off-main-thread,
so we need a placeholder until it can be filled in.

Now that rustfmt is getting close to stable, and work on the style system has died down a bit, it seemed like an opportune time to auto-format the style crates.
The first commit disables import reordering, since tidy and rustfmt don't currently agree on the correct ordering. The second commit does a bunch of manual fixups such that the output of rustfmt passes tidy. The third commit runs rustfmt on the three aforementioned crate.
There are a few dozen warnings in the style crate about lines longer than 100 characters. It would be good to fix these, but I don't have time for that now.

Otherwise removal of stylesheets may get out of sync with other DOM changes, and
we may fail to invalidate the style of the affected elements.

It logically belongs there, and the only reason it wasn't there before we were
working around other stuff. Now it's needed to share UA stylesheets across documents.

This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf
stuff already in Servo, except better. In particular, it adds deriving support
for MallocSizeOf, which will make it easier to improve coverage.
The patch does the following.
- Combines servo/components/style/stylesheets/memory.rs and the heapsize crate
into a new crate, malloc_size_of.
- Forks the heapsize_derive crate, calling it malloc_size_of, so that
MallocSizeOf can be derived.
- Both the new crates have MIT/Apache licenses, like heapsize, in case they are
incorporated into heapsize in the future.
- Renames the methods within MallocSizeOf and the related traits so they are
more concise.
- Removes MallocSizeOfWithGuard.
- Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an
equivalent or almost-equivalent hand-written implementation.
- Adds stuff so that Rc/Arc can be handled properly.

This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.
This is on top of #18143.
