Implement non-visible pipeline and iframe visibility methods
This addresses #9566 and a good part of #9751, specifically:
* Pipeline has a notion of visibility
* IFrame setVisible/getVisible interface with IFrame's pipeline visibility
* IFrame mozbrowservisibilitychange responds to changes in visibility
* Pipeline visibility is used to limit animations (requestAnimationFrame does not tick animations when hidden) and to increase timer intervals (currently set to a minimum of 1 second while hidden)
Absent for now are any changes to the Document API and general implementation of the Page Visibility API, since the more interesting parts require knowledge of whether the user agent is minimized, OS screen locked, etc.

Make the net monitor panel in FF's devtools show meaningful output.
<!-- Please describe your changes on the following line: -->
1. Advertise support for the network monitor in the initial protocol communication.
1. Only notify the developer tools server about the final request in an HTTP transaction.
1. Add timing information for connecting to the HTTP server and sending the HTTP request.
1. Reduce duplication between various networkEventUpdate structures by creating a helper function
that merges two JSON structures together. This also corrects the JSON structure so the devtools
client interprets the output correctly.
1. Calculate various header size fields correctly.
1. Remove unnecessary usize->u32 casts by making the appropriate fields usize.
1. Add header values to request and response header messages.
1. Support triggering page reloads via the devtools client.
I apologize that these aren't broken apart. I was making a lot of changes trying to figure out why the panel wasn't working right, and a lot of them were tangled together.

Add file backend support for Blob and related
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy --faster` does not report any errors
- [x] These changes fix#10851, related to #11131
- [x] These changes do not require tests because the implementation is partial and can't work alone
1. Add new backend to `Blob` and a `BlobImpl` struct to abstract multiple backends
2. Rewrite most interfaces of `Blob` to accommodate the change
3. Change the `read` behaviour of `FileReader`, considering the case when blob is file-backed and not cached
The design is still immature, welcome comments!
- [x] I used `DOMRefCell` to cache the bytes in `BlobImpl`, is it sound?
- [x] The interfaces (like `BlobImpl::get_bytes`) handle requests in a default-to-empty way when the inner `DataSlice` is not cached. It might be possible to handle this condition better.

Changes include:
- Add BlobImpl to Blob, and related caching mechanism
- Expose ResourceThreads to document_loader, workerglobalscope, worker, and global
- Fix encode_multipart_form_data
- Other small fixes to accommodate the above changes
WebRender.
This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.
Report blank lines that follow an open brace
This automates something that I find myself frequently commenting on in PRs.

We needed a separate thread in the chrome process because communication to the
compositor is done through a trait object, and cross-process virtual calls are
forbidden.
Also, the fact that these messages are ultimately handled by the compositor is
an implementation detail; conceptually, the relevant constellation is supposed
to handle these messages.
So instead, the script thread will now send the messages to the constellation,
which will ask the compositor to handle them.
Use associated types to improve LayoutThreadFactory and ScriptThreadFactory.
