Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.

http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

Fixes#13424
As of now this PR (Work in Progress), will try to implement (partially) on algorithms namely : [Schedule_Job](https://w3c.github.io/ServiceWorker/#schedule-job-algorithm), [Run_Job](https://w3c.github.io/ServiceWorker/#run-job-algorithm), [Register_Job](https://w3c.github.io/ServiceWorker/#register-algorithm).
An issue that needs to be addressed:
Resolving the promise value after queueing it as a `dom_manipulation_task` by wrapping it in a runnable `RunJobHandler` (which holds a `TrustedPromise`) and trying to call `resolve_native` results in a crash. [stack trace](http://paste.ofcode.org/zdjJ9npBgX6JsyWQkJjnYk)
@jdm I am not sure what's causing the crash ?

Still needs a bunch of code in net to be converted in order to get more
advantage of this for images and stuff, but meanwhile this should help quite a
bit with #13778.
Still wanted to get this in.
