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.

`stylo_tests` currently requires a separate version of the `style` crate, compiled with the `testing` feature, so a function testing the size of specified values can be accessed. With a few tweaks, we can make the information needed for the test available to the `stylo_tests` crate directly, eliminating the need for a separately-compiled `style` crate.
This doesn't matter much for Servo itself (it might make CI times slightly faster?), but Gecko automation/development would like to run `stylo_tests`, and not having to compile two versions of the `style` crate (or have a dead, test-only function hanging around in the `style` crate) would be a win.

This file has become quite bloated lately. This commit deletes that file in
favor of a set of submodules.
The only noticeable change apart from code move, is converting deep_clone_foo
methods into a trait.
It also unifies logic related to different style rules in the same place.
There's some missing work, specially related to font-face and counter-style, but
I think this is worth landing in the meantime.

Depends on https://github.com/servo/unicode-bidi/pull/27 , which
upgrades `unicode-bidi` crate to `0.3.0`.
Summary of changes:
* Use `unicode_bidi::Level` (instead of `u8`) in all relevant places and
replace magic computations with (inline) method calls to Level API.
* Doing so required adding `unicode-bidi` crate dependency to two more
components here: `style` and `gfx`. IMHO, totally makes sense, as
replaces local integer manipulations/checks with well-tested ones
already available in a common dependency.

This enum type used to contain the result of parsing one CSS source declaration (`name: value;`) and expanding shorthands. Enum types are as big as the biggest of their variant (plus discriminant), which was quite big because some shorthands expand to many longhand properties. This type was returned through many functions and methods, wrapped and rewrapped in `Result` with different error types. This presumably caused significant `memmove` traffic.
Instead, we now allocate an `ArrayVec` on the stack and pass `&mut` references to it for various functions to push into it. This type is also very big, but we never move it.
We still use an intermediate data structure because we sometimes decide after shorthand expansion that a declaration is invalid after all and that we’re gonna drop it. Only later do we push to a `PropertyDeclarationBlock`, with an entire `ArrayVec` or nothing.
In future work we can try to avoid a large stack-allocated array, and instead writing directly to the heap allocation of the `Vec` inside `PropertyDeclarationBlock`. However this is tricky: we need to preserve this "all or nothing" aspect of parsing one source declaration, and at the same time we want to make it as little error-prone as possible for the various call sites. `PropertyDeclarationBlock` curently does property deduplication incrementally: as each `PropertyDeclaration` is pushed, we check if an existing declaration of the same property exists and if so overwrite it. To get rid of the stack allocated array we’d need to somehow deduplicate separately after pushing multiple `PropertyDeclaration`.

To be aligned with the implementation from Gecko side, we parse
font-language-override as Normal keyword or String. Then, we compute
and store it as a u32. So, as to the stylo glue, we can just pass the
u32 to Gecko.
The extra crate, byteorder, is used to simplify the computing and
serialization.
Since we now implement font-language-override for Gecko, we can remove
the additional branches for font-language-override in font shorthand.

<!-- Please describe your changes on the following line: -->
Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.

By having a single thread pool, rather than one per document, we use less memory. This addresses https://bugzilla.mozilla.org/show_bug.cgi?id=1324250.
This may be obvious to an experienced Rust programmer, but I went with raw pointers because trying to use `Option` global variables resulted in complaints about turning on feature flags in nightly Rust. Since this is for stylo, nightly features are not appropriate here.

While reviewing @bzbarsky's patches in [1], I started typing out some lore about how mutable AtomicRefCell borrows are actually cheaper than immutable ones, so we should prefer them where possible. But then I decided that this was a really dumb state of affairs and that we should just fix AtomicRefCell instead, and implement a proper AtomicRef{,Mut}::map while we were at it. So here we are.
This PR adds a from-scratch implementation of AtomicRefCell that aims to be 100% sound, even in unrealistic overflow scenarios. We should probably get this on crates.io eventually, but I want to land it landed in-tree first.
With this implementation, each operation (borrow or release) is one atomic instruction, and all borrow/release pairs (mutable or immutable) take 12 ns on my machine, which is what I'd expect. This is a 50% improvement over the previous implementation in the immutable case.
There may be some places where we could get away with Ordering::Release instead of Ordering::AcqRel, but it didn't seem worth it to try to reason it out.

<!-- Please describe your changes on the following line: -->
The current work queue had a really annoying constraint: The size of the node had to be the size of the work unit data.
This makes it impractical for the new restyling model where we plan to pass down a bunch of data.
Rayon by default makes you wait for the result of the work unit, which makes it impractical for the current model (it's mostly sequential).
I added an API to rayon that allows us to push work to the queue without waiting (https://github.com/nikomatsakis/rayon/pull/103).
This still needs some work (for example, we're loosing the memory reporting functionality), but I wanted feedback on this.

This patch introduces infrastructure for the rule tree, and constructs it.
We don't use it yet, nor have good heuristics for GC'ing it, but this should not
happen anymore once we store the rule node reference in the node.

Previously, `string-cache` defined:
* An string-like `Atom` type,
* An `atom!("foo")` macro that expands to a value of that type, for a set of strings known at compile-time,
* A `struct Namespace(Atom);` type
* A `ns!(html)` macro that maps known prefixed to `Namespace` values with the corresponding namespace URL.
Adding a string to the static set required making a change to the `string-cache` crate.
With 0.3, the `Atom` type is now generic, with a type parameter that provides a set of static strings. We can have multiple such sets, defined in different crates. The `string_cache_codegen` crate, to be used in build scripts, generates code that defines such a set, a new atom type (a type alias for `Atom<_>` with the type parameter set), and an `atom!`-like macro.
The html5ever repository has a new `html5ever_atoms` crate that defines three such types: `Prefix`, `Namespace`, and `LocalName` (with respective `namespace_prefix!`, `namespace_url!`, and `local_name!` macros). It also defines the `ns!` macro like before.
This repository has a new `servo_atoms` crate in `components/atoms` that, for now, defines a single `Atom` type (and `atom!`) macro. (`servo_atoms::Atom` is defined as something like `type Atom = string_cache::Atom<ServoStaticStringSet>;`, so overall there’s now two types named `Atom`.)
In this PR, `servo_atoms::Atom` is used for everything else that was `string_cache::Atom` before. But more atom types can be defined as needed. Two reasons to do this are to auto-generate the set of static strings (I’m planning to do this for CSS property names, which is the motivation for this change), or to have the type system help us avoid mix up unrelated things (this is why we had a `Namespace` type ever before this change).
Introducing new types helped me find a bug: when creating a new attribute `dom::Element::set_style_attr`, would pass `Some(atom!("style"))` instead of `None` (now `Option<html5ever_atoms::Prefix>` instead of `Option<string_cache::Atom>`) to the `prefix` argument of `Attr::new`. I suppose the author of that code confused it with the `local_name` argument.
---
Note that Stylo is not affected by any of this. The `gecko_string_cache` module is unchanged, with a single `Atom` type. The `style` crate conditionally compiles `Prefix` and `LocalName` re-exports for that are both `gecko_string_cache::Atom` on stylo.
