SpiderMonkey provides an extremely fine-grained breakdown of memory
usage, but for Servo we aggregate the measurements into a small number
of coarse buckets, which seems appropriate for the current level of
detail provided by Servo's memory profiler. Sample output:
```
| 17.41 MiB -- url(file:///home/njn/moz/servo/../servo-static-suite/wikipedia/Guardians%20of%20the%20Galaxy%20(film)%20-%20Wikipedia,%20the%20free%20encyclopedia.html)
| 7.32 MiB -- js
| 3.07 MiB -- malloc-heap
| 3.00 MiB -- gc-heap
| 2.48 MiB -- used
| 0.34 MiB -- decommitted
| 0.09 MiB -- unused
| 0.09 MiB -- admin
| 1.25 MiB -- non-heap
```
Most of the changes are plumbing to get the script task communicating
with the memory profiler task.

Didn't touch mozjs or rust-mozjs because implementing that in the code generator didn't seem too easy. I'm using the same workaround that the TextDecoder does.
Using the OsRng should be the right choice here? As the OS keeps state for us we wouldn't need to have a global rng instance to keep around.
Fixes#4666.

fixes#6524. I had to make an additional change not mentioned in the ticket - adding the `#[feature]` to enable deriving custom traits but I assume that's expected at this time.

> Here it is.

> ~~There's two major things that are unfinished here:~~
> - ~~Dealing with the unroot_must_root lint. I'm not sure about the value of this lint with the new rooting API.~~ Done.
> - ~~Updating the Cargo.locks to point to the new SM and SM binding.~~ Done.
>
> I also included my fixes for the rust update, but these will disappear in a rebase. A rust update is necessary to support calling `Drop` on `Heap<T>` correctly when `Heap<T>` is inside a `Rc<T>`. Otherwise `&self` points to the wrong location.
>
> Incremental GC is disabled here. I'm not sure how to deal with the incremental barriers so that's left for later.
>
> Generational GC works. SM doesn't work without it.
>
> The biggest change here is to the rooting API. `Root` was made movable, and `Temporary` and `JSRef` was removed. Movable `Root`s means there's no need for `Temporary`, and `JSRef`s aren't needed generally since it can be assumed that being able to obtain a reference to a dom object means it's already rooted. References have their lifetime bound to the Roots that provided them. DOM objects that haven't passed through `reflect_dom_object` don't need to be rooted, and DOM objects that have passed through `reflect_dom_object` can't be obtained without being rooted through `native_from_reflector_jsmanaged` or `JS::<T>::root()`.
>
> Support for `Heap<T>` ended up messier than I expected. It's split into two commits, but only because it's a bit difficult to fold them together. Supporting `Heap<T>` properly requires that that `Heap::<T>::set()` be called on something that won't move. I removed the Copy and Clone trait from `Heap<T>` so `Cell` can't hold `Heap<T>` - only `UnsafeCell` can hold it.
>
> `CallbackObject` is a bit tricky - I moved all callbacks into `Rc<T>` in order to make sure that the pointer inside to a `*mut JSObject` doesn't move. This is necessary for supporting `Heap<T>`.
>
> `RootedCollectionSet` is very general purpose now. Anything with `JSTraceable` can be rooted by `RootedCollectionSet`/`RootedTraceable`. Right now, `RootedTraceable` is only used to hold down dom objects before they're fully attached to their reflector. I had to make a custom mechanism to dispatch the trace call - couldn't figure out how to get trait objects working for this case.

> This has been tested with the following zeal settings:
>
> GC after every allocation
> JS_GC_ZEAL=2,1

It would be nice if HTML parsing didn't have to hog the event loop, so I didn't have to do this polling in `content_changed()`, but maybe the way we do it is unavoidable.

* Simpler image cache API for clients to use.
* Significantly fewer threads.
* One thread for image cache task (multiplexes commands, decoder threads and async resource requests).
* 4 threads for decoder worker tasks.
* Removed ReflowEvent hacks in script and layout tasks.
* Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe.
* Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow.
* Add reflow batching for when multiple images load quickly.
* Reduces the number of paints loading wikipedia from ~95 to ~35.
* Reasonably simple to add proper prefetch support in a follow up PR.
* Async loaded images always construct Image fragments now, instead of generic.
* Image fragments support the image not being present.
* Simpler implementation of synchronous image loading for reftests.
* Removed image holder.
* image.onload support.
* image NaturalWidth and NaturalHeight support.
* Updated WPT expectations.

This implements a framework for opting in to receiving network events asynchronously. It also converts XMLHttpRequest to use them, and paves the way for better support for synchronous XHR using on-demand, targeted event loops instead of spinning the global event loop. This gives us complete feature parity with the existing XHR implementation, using fewer threads than before in the async case.

properties are `top`, `right`, `bottom`, and `left`. However, all other
features of transitions are supported. There are no automated tests at

For the majority of these cases, `as_slice` can be removed due to
`Deref`. In particular, `Deref` for:
* `String` -> `str`
* `Atom` -> `str`
The latter of those two requires, a bump of the locked `string-cache`

@jdm This initial version has a few outstanding issues that I wanted to invite input on. Specifically:
1. I had some difficulty finding a home for the `StorageType` enum. Structs defined outside of the `script` module don't seem to be able to use the `#[jstraceable]` annotation and the `net` module (where `StorageTask` lives) doesn't have access to `script`. Per Simon Sapin's suggestion, I worked around this temporarily by creating a `TraceableStorageType` stand-in struct that was traceable and which could be translated into a regular `StorageType` when being sent to the `StorageTask`. Unsure of the best way to resolve this hack. Thoughts?
2. Apart from the `Storage` constructor used in `Window::SessionStorage` and the new `Window::LocalStorage`, there's also a method called `Storage::Constructor`. I'm unclear on what (if anything) will actually invoke this, so I'm not sure which variant of `StorageType` to use here. I've temporarily created an `Unknown` variant of `StorageType` as a placeholder.
3. I discovered that the web platform tests directory's localStorage tests. Many of them now pass despite the configured expectation that they fail. However, several do not pass. Is there a good way for me to add debug logging or otherwise get a sense of which assertion failed / what went wrong?
Thanks for your continued help!
