Share specified URLs with Gecko
This makes use of our Arc offset machinery to allow Gecko to store Arc<String> values and ensure there are used appropriately.

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:

The devtools feature bug is here:

This patch changes servo to preserve and expose this value for use in M-C.
style: Move ExtraStyleData into CascadeData.
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.

Gecko would like to turn on the stylo layout tests (tests/unit/stylo) in
Gecko CI. The plan for doing this is to add the tests as a
dev-dependency of Gecko's main Rust library, from which `cargo test` can
be run in the usual fashion.
Doing this creates problems for normal development, because the stylo
tests need the `selectors` crate to be compiled with `gecko_like_types`,
whereas the `geckolib` crate does not. So if we compile `geckolib` in a
non-test build configuration, the `selectors` crate is compiled without
`gecko_like_types`...but then if we compile `geckolib` in a test build
configuration, cargo will evict the previous rlib for the `selectors`
crate and replace it with a `selectors` compiled with gecko_like_types.
And then compiling `geckolib` in a non-test configuration repeats the
process, and so forth.
Needless to say, this is highly annoying behavior. It is due to a bug
in cargo:
https://github.com/rust-lang/cargo/issues/3923
but it's not known when that bug will get fixed. In the meantime, we
can just make sure that geckolib's `selectors` is compiled with the same
features as the `selectors` crate in the stylo tests.
Invalidation should check all restyle hints.
For some cases simply check EffectCompositor is not enough, we need to check the dirty bits for animation too.

Now that rust-cssparser reports 1-based locations, bump the required
cssparser version and remove get_location_with_offset. Previously,
some code paths were not calling get_location_with_offset; see
https://bugzilla.mozilla.org/show_bug.cgi?id=1398869 for some
background.
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.
Update rust-cssparser to 0.20.2.
This reduces memory consumption of list-valued properties in the common case of one entry in the list.

We were parsing @page rules correctly and serializing for cssom when we
we need. But we weren't actually including them to the pseudo element
declarations when we need to print a page.

stylo: Store location information for keyframe rules.
So far, we only store location info for the whole Keyframes block, not for each
of the keyframe rule. Without this info, the devtool can't present the rules
on the devtool panel properly.
In this patch, we collect the source location info while parsing keyframe selector.
The binding function, Servo_KeyframesRule_GetKeyframe, is also fixed (and renamed
to Servo_KeyframesRule_GetKeyframeAt to match the fix) to accept line and column
parameters from Gecko, so we can pass/set them with the source location from Servo.
This is the servo part of [Bug 1394994](https://bugzilla.mozilla.org/show_bug.cgi?id=1394994).

Make the order of rules in DevTools be the specificity order.
We insert rules with any important declaration into rule tree twice,
one for the normal level and another for the important level. And
when we fetch them from rule tree, we skip the important one to
make the order be the specificity order.
