This commit adds angle-based validation and translation to WebGL
shaders.
The changes to the tex_image_2d test is neccessary (it was not valid
GLES 2.0 shader language).
Parse :active pseudo-class selector.
This is #7258 with a spec link added in doc-comment.
The pseudo-class is never matched, but this can still help with stylesheets like `a:hover, a:active { color: something }` where failing to parse one pseudo-class makes the entire selector list invalid.
I filed #7333 about actually making it match.

Integrate with simple Heartbeats
This PR adds Heartbeats capability to servo. Heartbeats are used for detailed performance and power/energy profiling. We will add the power/energy readings in the future.
New dependencies are introduced which need in-depth reviews. I'm the only one who has had eyes on any of this, and I have limited resources for testing cross-platform compatibility.
* https://github.com/libheartbeats/heartbeats-simple - provides native C libraries from a shared code base:
* hbs[-static] - performance monitoring
* hbs-acc[-static] - performance with accuracy monitoring
* hbs-pow[-static] - performance with power/energy monitoring (the one we're using)
* hbs-acc-pow[-static] - performance with accuracy and power/energy monitoring
* https://github.com/connorimes/heartbeats-simple-sys provides rust wrappers for the native C libraries above - one crate for each + a common crate. These link with the *-static versions of the heartbeats libraries.
* https://github.com/connorimes/heartbeats-simple-rust provides rust abstractions over the -sys crates above - one crate for each.
The new `heartbeats` module in the `profile` crate looks for environment variables telling it to use heartbeats for each ProfilerCategory and where to put log files. (Of course, if somebody knows how to iterate over the enum instead of hardcoding each one, that would be fantastic.) If the environment variables aren't set for particular categories, heartbeats aren't created or used.
An interface change is made in the `profile_traits` crate to pass both the start and end time in a `ProfilerMsg` instead of just the elapsed time. Later we will add energy readings as well.

I couldn't find the place in the spec where the precise behavior of
`:active` is described, so I don't set it. However, all the machinery to
keep track of its status is in place.
Improves YouTube.
Upgrade Rust to nightly 2015-08-10
Still needs snapshot.
Snapshot probably could also work as today's nightly (I wasn't able to download the latest one due to choppy internet), there isn't any plugins churn I know of

This excludes:
* cssparser, as it contains changes that cause test failures;
* tenacious, as it has not yet been updated to the current rustc
(Manishearth/rust-tenacious#6);
* ipc-channel, as it doesn't build on linux upstream.
Send display lists over IPC in multiprocess mode.
This patch set introduces the `--multiprocess` (`-M`) switch. Right now, all it does it cause display lists to be serialized, but eventually it will cause actual processes to be spawned.
