This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.
The spec removed it. Check the scheme instead, data is always same origin now,
except for workers.
This also updates the comments to make step numbers match the spec.
Closes#13362
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.

This commit adds new files related to implementing the [Request
API](https://fetch.spec.whatwg.org/#request-class). This commit also
changes the expected web platform tests results. It also modifies the
following files:
components/net_traits/request.rs
HeapSizeOf is implemented in net_traits/request so that dom::request can
be used as a wrapper around net_traits::request::Request.
components/script/dom/headers.rs
Several methods are added to Headers so that request can access and
modify some of the headers fields.
Fix FileAPI's refcount implementation
Revise several intricate parts of FileAPI's internal refcounting-related implementation.
Goal: Get it done right once and for all.
