selectors: Manually inline any(..) in matches_selector_list.

Since the compiler refuses to inline the inner closure even with -O3, which is
sad :(.

selectors: Add parsing support for ::slotted().
Without turning it on yet, of course.

The reason why I didn't use the general PseudoElement mechanism is because this
pseudo is a bit of its own thing, and I found easier to make ::selectors know
about it (because you need to jump to the assigned slot) than the other way
around.

Also, we need to support ::slotted(..)::before and such, and supporting multiple
pseudo-elements like that breaks some other invariants around the SelectorMap,
and fixing those would require special-casing slotted a lot more in other parts
of the code.

Let me know if you think otherwise.

I also don't like much the boolean tuple return value, but I plan to do some
cleanup in the area in a bit, so it should go away soon, I'd hope.

selectors: Simplify :visited by only using the "is inside link" information.
Right now we go through a lot of hoops to see if we ever see a relevant link.

However, that information is not needed: if the element is a link, we'll always
need to compute its visited style because its its own relevant link.

If the element inherits from a link, we need to also compute the visited style
anyway.

So the "has a relevant link been found" is pretty useless when we know what are
we inheriting from.

The branches at the beginning of matches_complex_selector_internal were
affecting performance, and there are no good reasons to keep them.

I've verified that this passes all the visited tests in mozilla central, and
that the test-cases too-flaky to be landed still pass.

style: Hide LocalMatchingContext.
This type is a lot of complexity related to a very specific thing such as the
hover and active quirk.

Instead of that, move `nesting_level` to `MatchingContext`, and simplify all
this computing whether the quirk applies upfront, for each complex selector we
test.

This is less error-prone, and also allows simplifying more stuff in a bit.

c48226ff6f Preserve sourceURL comment on style sheets
In addition to the sourceMappingURL comment, there is a second special
comment, "sourceURL", that can be used to set the "display name" of a
style sheet for developer tools.  This name is also used as the base
URL for the source-map URL resolution algorithm.  sourceURL is
described here:
https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/

32548e5312 Overhaul MallocSizeOf and related things.
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.
