Add mach build-stable to build with stable rustc
<!-- Please describe your changes on the following line: -->
Added mach subcommand (build-stable) to build servo and its dependencies using a stable version of rustc.

- [X] These changes do not require tests because they're in the build process. I've manually tested both build and build-stable several times and in different orders and it seems to work. If the mach subcommands are tested automatically somewhere, I'll be happy to add a test, but I couldn't find it.
This is an example of output I get, which is what I'd expect:

Github issue: #11806
Building with current stable rust (1.9.0) still fails because of
feature pragmas in some dependencies (e.g. serde_item).

Replace return_address usage for rooting with stack guards and convenience macros.
The existing `Rooted` and `RootedVec` users were migrated the the following two macros:
```rust
let x = Rooted::new(cx, value);
// Was changed to:
rooted!(in(cx) let x = value);
// Which expands to:
let mut __root = Rooted::new_unrooted(value);
let x = RootedGuard::new(cx, &mut __root);
```
```rust
let mut v = RootedVec::new();
v.extend(iterator);
// Was changed to:
rooted_vec!(let v <- iterator);
// Which expands to:
let mut __root = RootableVec::new();
let v = RootedVec::new(&mut __root, iterator);
```
The `rooted!` macro depends on servo/rust-mozjs#272.
These APIs based on two types, a container to be rooted and a rooting guard, allow implementing both `Rooted`-style rooting and `Traceable`-based rooting in stable Rust, without abusing `return_address`.
Such macros may have been tried before, but in 1.9 their hygiene is broken, they work only since 1.10.
Sadly, `Rooted` is a FFI type and completely exposed, so I cannot prevent anyone from creating their own, although all fields but the value get overwritten by `RootedGuard::new` anyway.
`RootableVec` OTOH is *guaranteed* to be empty when not rooted, which makes it harmless AFAICT.
By fixing rust-lang/rust#34227, this PR enables Servo to build with `-Zorbit`.

Integration and improvements of File API backends
Basically three major changes:
1. More complete origin check in `FileManagerThreadMsg`
2. Add reference counting logic to file manage store and script API
3. Integrate the support of slicing

This commit adds a need_index prop to the style system, and autogenerates
iterators, and a get_xxx_mod(i) function from a get_xxx_prop() and
get_xxx_at(index) functions.
This allows us to (finally!) take rid of the as_servo() hack. There are a few
unimplemented clones, but I'm just too lazy for that right now.
style: Remove the Mutex from new_animations_sender by moving it to the local StyleContext.

As a follow-up, we could move all the data living under a mutex in the
SharedLayoutContext only in order to create the local context to the same place.
This should increase animation performance when there are multiple animations in
one page that happen to be on different threads.

This takes the Glutin upgrade intended for #11130 but does not address
the underlying issue. A FIXME has been added.

The clang-3.8 instead of clang++-3.8 check is because on some Linux distros
clang++-3.8 doesn't exists, while the former does.
