style: Don't remain in an invalid state when encountering an at-rule in the wrong place.
Currently, attempting to parse an at-rule that is out of place, such as
an @import rule after a regular style rule, will cause the parser state
to be set to Invalid. This will cause any following at-rule to be
rejected until we encounter a regular style rule, at which point we'll
go back to the Body state. There's nothing in the CSS specs about
needing to reject all following at-rules (or, as the comment above
Invalid says, ignoring the entire rest of the style sheet).

Use AntialiasMode in CanvasPaintThread::new

I only changed `canvas_paint_thread.rs` since `CanvasPaintThread::start` is used outside of the current crate and `azure::azure_hl::AntialiasMode` isn't available there.

WR multi-document update

The PR updates WR version to support multiple documents (https://github.com/servo/webrender/pull/1509) but doesn't take advantage of this new feature yet.
It also makes Servo to use `DevicePixel` from WR instead of rolling out another one.

Servo's async Tokenizer: New! Improved! Now with multithreading!
<!-- Please describe your changes on the following line: -->
The Tokenizer, defined in the file `async_html.rs` will run on the main thread, while h5e's `Tokenizer`(along with its Sink) lives on the parser thread. Both h5e's `Tokenizer` and `Sink` communicate with the main thread Tokenizer via their own mpsc channels. The Sink keeps sending parser operations to the main thread, to be executed. For some operations, it waits for a message from the main thread before returning.

We already have a more-specific check further down in the file, which was added in the same revision.
I think this one was erroneous.
MozReview-Commit-ID: CnP0zCpBtnp
Cargo will already traverse up the directory hierarchy to find an
appropriate workspace, so we don't need to specify anything here. This
change brings components/atoms/Cargo.toml in line with other Cargo.toml
files in the tree.
