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.

Servo WebVR implementation started when WebVR spec 1.2 was about to be released. 1.2 API included some minor breaking changes from spec 1.1 in order to improve the support of the API in WebWorkers.
But eventually the WebVR committee decided not to release 1.2 and make it a major version number with a lot more changes. WebVR API 2.0 is still under heavy churn.
This PR removes the WebVR changes that non-released 1.2 version introduced to support full WebVR 1.1 spec.
I pushed some GC fixes in a separate commit. See https://github.com/servo/servo/issues/17076 and https://github.com/servo/rust-mozjs/issues/351

Heap::new() constructor is unsafe. Heap should be set after reflect_dom_object call in order to prevent potential GC crashes.

This PR allows different `Window` objects in the same browsing context to share a `BrowsingContext` object.
SpiderMonkey requires a `WindowProxy` object to be in the same compartment as its `Window`, so when a `WindowProxy` changes `Window`, we have to brain-transplant it. In turn this requires the reflector of a `BrowsingContext` to be mutable.

WebVR API Implementation with HTC Vive support on Windows. The current implementations only enables the WebVR support on Windows. In other platforms the API is available on JavaScript but navigator.vr.getDisplays() returns an empty array. This will change when we add support for more VR providers and platforms ;)

Proprietary openvr.dll must be copied next to servo.exe in order to test on HTC Vive (https://github.com/ValveSoftware/openvr/tree/master/bin/win64) I have added some of the official WebVR samples for testing. Switch on your headset and run:
