style: Add a "start_end()" method to LogicalMargin
<!-- Please describe your changes on the following line: -->
Add a `LogicalMargin::start_end()` method that receives a `Direction' parameter. This is useful for some layout that is symmetric in inline and block directions, like flexbox.
Part of #14123.

Add a generic type for sharing some CSS types
<!-- Please describe your changes on the following line: -->
This would be useful for types such as `T(pub Option<U>)` or any type that's a mixture of two types (like `LengthOrFoo` for example). Well, it's a bit ugly, especially because we have to address the types as `Either::First` and `Either::Second` everywhere, but I don't have a brighter idea 😄

Network Security : Implement StrictOrigin and StrictOriginWhenCrossOr…
This pull request contains commit implementing initial steps for Improving Network Security project. As part of initial steps referer policy enums for strict-origin and strict-origin-when-cross-origin have been added to [hyper](https://github.com/hyperium/hyper/pull/943). Unit tests and additional logic has been added to handle these policies. Since enum changes are available on hyper version 0.9.11. We had to update hyper version to 0.9.11.
Hyper 0.9.11 depends on num_cpus 1.1.0. To avoid different version of num_cpus. We have updated rayon version from 0.4.0 to 0.4.3. Cargo.toml of util, style, geckolib, stylo component has been updated to use num_cpus version 1.1.0 instead of 0.2.2.

Referer policy strict-origin and strict-origin-when-cross-origin changes have been implemented. Relevant unit test cases have been added. Enum for RefererPolicy has been added to hyper codebase and v 0.9.11 of hyper contains these changes.
This commit also contains changes related to upgrade of hyper from v0.9.10 to v0.9.11. Other dependencies changed are rayon, utils, num_cpus.

RuleTreeDeclarationsIterator would yield &PropertyDeclaration
with the lifetime of the rule tree, but the reference would only
be valid as long as the iterator was holding the corresponding lock.
The lock would be released when the iterator’s `.next()` method
moves to the next rule tree node, or when the iterator is dropped.
Also change apply_declaration to not require a `Clone` iterator
(since closures unfortunately don’t implement `Clone`).
Instead have it take a callable that returns a fresh iterator.
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.
I haven't messed up with memory orders because I want to do a try run with it,
then mess with them.
Take down the ApplicableDeclarationsCache, use the rule tree for doing the cascade.

Update to string-cache 0.3
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.
