This is a direct extract from my abandoned PR for a lint (#7546), along with some rather clumsy modifications (only on `components/script/dom/mod.rs` and `components/style/lib.rs`), because I had to sort some of the files again to make peace with tidy, which hasn't been educated about sorting yet!

The integration is off by default for now. You can try it out with `./mach build --features "script/plugins/clippy"`.
We're using a branch of clippy with some of the lints changed to Allow, either because they don't apply to us, or because they're noisy and dwarf other warnings (but still should be fixed)
After going through the rest of Servo's warnings I'll figure out which lints we should be keeping.
There's a cargo bug with optional deps that makes it hard for this to work with Cargo.lock -- so this PR contains no changes to lockfiles (and running the build with clippy on may dirty the lockfile, though it gets fixed later)

Also adds HeapSizeOf implementations/derive for some types. I've used "Cannot calculate Heap size" as a reason everywhere, because my imagination is rather limited. If you'd like me to change this message for specific types, please write something like this: "Trusted - Cannot calculate Heap size for Trusted" so that it would be easier for me to replace them through a script :)

…s for frame treese in script tasks.
This underreports by a significant amount, since only Document, Window and CharacterData (ie. text) nodes are fully represented. That being said, every HTML element in the tree is measured, but only counted as a Node. It's easy to improve this, it just requires adding the appropriate HeapSizeOf derives and increasing the granularity of `measure_memory_for_eventtarget`. google.com shows a dom-tree value of 0.24 MB for me at the moment.

To actually make the multiprocess communication work, we'll need to
reroute the task creation to the pipeline or the compositor. But this

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.

> - ~~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 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.

This replaces the specialized TrustedXHRAddress and TrustedWorkerAddress code that was used for the same purpose. A non-zero refcount pins the given DOM object's reflector and prevents it from being GCed even when there are no other outstanding references visible to SpiderMonkey. This will enable us to implement asynchronous operations that refer to particular DOM objects (such as "queue a task to fire a simple event named load at the iframe element" from the spec) safely and conveniently, and paves the way for things like asynchronous network responses.
Some concerns about the resulting size of XHR progress messages have been expressed, but I believe optimizations to reduce that can be implemented in subsequent PRs.
r? @Ms2ger - note in particular the changes to the worker lifetime code. I couldn't figure out how to achieve an identical lifetime to the previous addref/release pairing, and I also was having trouble figuring out why the existing setup was safe. The new implementation now holds the main script task Worker object alive via the TrustedWorkerAddress field in the dedicated worker global scope, which is a significant difference.
