TODO
- [ ] cache metadata (find some subset of`net_traits::Metadata` that can be shared across threads, it seems the problem is mainly stuff inside `hyper::header` in the `headers` field)
- [ ] determine which other fields of a `Response` need to be cached, so a full and valid one can be returned upon a cache hit.
- [ ] determine how to best share the cache across fetch threads (inside HttpState like I tried now?)
- [ ] Spend more time reading the spec and make sure the cache follows it where it matters.
- [ ] Make the current wpt tests pass.

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.

<!-- Please describe your changes on the following line: -->
This PR implements the fetch method, which is described in [the Fetch Spec](https://fetch.spec.whatwg.org/#fetch-method). The expected wpt results are updated as well.
A few comments about the current fetch implementation:
- The fetch method manually calls `JSAutoCompartment` in order to prevent SpiderMonkey from crashing. This may have to change in the future.
- Not all `FetchResponseListener` methods are implemented.
- `net_traits::CoreResourceMsg::Fetch` message takes a `net_traits::request::RequestInit`. However, when the fetch method is called, a `RequestBinding::RequestInit` is given. The fetch method constructs a `dom::request::Request` with the given `RequestInit`, then creates `net_traits::request::RequestInit` from the dom Request object for the fetch message.

<!-- Please describe your changes on the following line: -->
This PR adds the [dom::Response](https://fetch.spec.whatwg.org/#response-class) implementation and addresses #11896.
The relevant passing tests` expectations have been updated.
In order to allow non-UTF-8-encoded status messages, `net_traits::response::Response`'s `raw_status` field has been changed from type [`Option<RawStatus>`](https://doc.servo.org/hyper/http/struct.RawStatus.html) to type `Option<(u16, Vec<u8>)>`. As a result, a few other files which rely on the `raw_status` field were affected and updated.
TODOs:
- The `body` and `trailer` methods. Relies on implementation of `ReadableStream` and `Promise`s.
- Similarly, replace the dummy constructor `_body: Option<USVString>` argument with `body: ResponseBodyInit`.
- Currently, whenever `r's response's header list` or `r's Headers object` are mentioned, I always modify the `headers_reflector` field (of type dom::Headers, or `r's Headers object`) and not the corresponding hyper::Headers list in the net_traits::Response field. A completely accurate interpretation of the spec might consider making both of these lists the same thing via a reference. [Discussion](https://github.com/whatwg/fetch/issues/358) was [had](https://github.com/servo/servo/pull/12884).

The changes in headers.rs will allow headers with "content-type" name to be classified as cors safelisted request headers, depending on its value according to [the Fetch spec](https://fetch.spec.whatwg.org/#cors-safelisted-request-header). As a result of this change, more request web platform tests pass, whose expected test results are updated with this commit.
There is possibly one TODO related to this PR:
- Figure out what `name/'invalid'` is in step 4 of the [Headers Delete method](https://fetch.spec.whatwg.org/#dom-headers-delete), and how to implement that.

Implement the Request API
<!-- Please describe your changes on the following line: -->
This PR implements the [Request API](https://fetch.spec.whatwg.org/#request-class) for the Fetch API, including its attributes and constructor, and introduces changes in relevant files.
This Request integrates `net_traits::request::Request` and `dom::headers`.
There are few related TODOs and comments:
1. `net_traits::request::Request`'s `headers` field does not point to `dom::request::Request`'s `headers_reflector`.
2. Every Constructor step that involves `Readable Stream` object is not implemented.
3. Every Constructor step that involves `entry settings object` or `environment settings object` is not implemented.
4. `./mach build -d` does not report any error, but prints a few warnings about unused variables related to (1) and (2).
5. Enum `ReferrerPolicy` generated by `RequestBinding` does not match `net_traits::request::Request`'s implementation.
6. `Promise`s in Body webidl are commented out.

<!-- Please describe your changes on the following line: -->
This PR fills out the constructor and the delete, get, has, and set methods for the Headers API. Addresses issue #11897 .
The PR also rewrites the append method to support `hyper::header::Headers`'s HashMap `insert` method, which overwrites entries instead of appending.
As a result of this, for a given header name there is at most one value in the inner "header list"/HashMap. Multiple values for the same name are comma-delimited.
There are still a few TODOs:
- Support `OpenEndedDictionary<ByteString>` as a possible `HeadersInit` value. [OpenEndedDictionary<T> is a future IDL construct.](https://fetch.spec.whatwg.org/#headers-class)
- Support `iterable<ByteString, ByteString>`. Related issue: #12628
- Values are comma-delimited, except for values with the name `set-cookie`, which are newline-delimited. This is because values for `set-cookie` are [allowed to contain](https://tools.ietf.org/html/rfc7230#section-3.2.2) inner commas. This violates the [spec](https://fetch.spec.whatwg.org/#concept-header-value-combined).
- The TODOs from PR #12467 regarding value parsing also still need to be resolved.

This commit adds the append method for the Headers API. @malisas and I are both contributors.
There are a few TODOs related:
- The script needs to parse the header value for certain header names to decide the header group it belongs
- There are possible spec bugs that could change what a valid header value looks like (related: [issue page](https://github.com/whatwg/fetch/issues/332))
There are WPT tests already written for the Headers API, but they will fail as the Headers API is not fully implemented.
