Add <audio> and <video> player backends
These patches enables audio and video playing inside Servo.
It is bit hackish way to enable it, thus the purpose of this pull request is for an early request for comments.
It is tested with the current servo-media GStreamer backend in Linux.
~~The produced layout is not correct, since the elements after the video seems to be stacked behind, and the same with the scrolling bars.~~
~~There is no JavaScript interface yet~~, neither controls.

Previously, the `tests` feature flag of the `embedder_traits` crate
caused it and every crate recursively depending on it to be built twice.
This feature flag was used to provide a specific set of "resources"
when running tests. Instead, this commits overrides the `main()` function
of the test harness to change resources at runtime before running any test.
This is done by adding a dependency that has `name = "test"` in its
`[lib]` section of `Cargo.toml`. This overrides the crate found by
`extern crate test;` in code generated by `rustc --test`.
Enable fake fillText API in nightly builds.
The [three.js examples](https://threejs.org/examples/) are really useful for checking Servo WebGL support, but if the fillText API is not available they only display a blank screen. I think it's worth lying to web content about this API in order to make it easy to make use of these examples without using local development builds.

Implement BiquadFilterNode
A bunch of tests still fail but some of it may be a timing issue, looking at it the tests are *at least* affected by https://github.com/servo/servo/issues/21659 (changing how they work to avoid problems from that does not make them pass but does change the exact value of the error), so I feel like I should fix that first before investigating these.

Implement AnalyserNode
<s>Needs https://github.com/servo/media/pull/127 to land (and a dependency
update)</s>
r? @ferjm
realtimeanalyser-fft-scaling.html, the test that actually checks for some level of FFT correctness, sadly doesn't work since we don't process nodes not connected to the destination.
However I locally fixed the test to work differently and it passed. We'll fix the processing model eventually.
