Implement missing functionality of AudioBufferSourceNode
<!-- Please describe your changes on the following line: -->
This is a tiny PR to support [Media #293](https://github.com/servo/media/pull/293). Last time I ran WPT there was only one failing AudioBufferSourceNode test (which I will debug later this week). Once I rebased, however, I started getting unrelated servo-media build failures:
```
error[E0599]: no method named `shutdown_audio_context` found for type `std::sync::Arc<servo_media::ServoMedia>` in the current scope
--> components/script/dom/baseaudiocontext.rs:566:14
error[E0599]: no method named `shutdown_player` found for type `std::sync::Arc<servo_media::ServoMedia>` in the current scope
--> components/script/dom/htmlmediaelement.rs:1866:18
```
I wanted to get this PR up so https://github.com/servo/media/pull/293 can be tested. When the unrelated build failures are fixed, I will run `./mach update-wpt` and update this PR.

Fix build error when using the 'webgl_backtrace' feature
This patch fixes a build error that happens when building with `--features webgl_backtrace`.
However, while working on this I've noticed that calling `Backtrace::new()` instantly causes a segmentation fault. This didn't happen with the example code of [the package](https://crates.io/crates/backtrace) though, so I wasn't sure where to report this (maybe related: [backtrace-rs/#150](https://github.com/rust-lang/backtrace-rs/issues/150), [backtrace-rs/#189](https://github.com/rust-lang/backtrace-rs/issues/189)).
