Put back video metadata
I updated the `video-metadata-rs` crate: now, no more ffmpeg, just pure rust. The webm format isn't checked yet.

Response API
<!-- 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).

Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Handle specialized serialization of <position> in basic shapes
Fixes#13083
We temporarily broke basic-shape serialization in #13042 when 4-value positions were implemented, since I didn't want to increase the scope of that PR too much.
This fixes it.

Handle row borders in border collapsing logic.
<!-- Please describe your changes on the following line: -->
Handle table row border when collapsing borders for a table row. The row border is combined with the cell's border using the already implemented conflict resolution logic.
This is a screenshot of the following test:
```html
<!doctype html>
<html><body>
<style>
table {
border-collapse: collapse;
}
tr {
border: 1px solid black;
}
</style>
<table>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
</table>
</body>
</html>
```
<img src="https://dl.dropboxusercontent.com/u/10962672/Screenshots%20Servo/servo_tr_border_collapse.png"/>
The top border is missing, but I think that's a different bug, since it also does not show up when the border is in the cells, and not the rows. Also, when debugging the border collapsing structures, they seem ok (the top border seems to be there). I can look at that bug in a separate issue (or in this one too if you prefer).
