This change fixes tests on Chromecast by loading tests later in the process. Test scripts are now dynamically inserted by boot.js, rather than loaded by Karma. The bootstrapping code then awaits the completion of that before starting the Karma frameworks (Jasmine) to run the tests.
This also removes the use of goog.provide/goog.require in tests and test utils. We don't need to load test utils or library sources dynamically in each test, and this gives us more explicit control over script loading and ordering.
Closes#4094
When unboxing TKHD, the reader read int64 as trackId instead of int32. Thus unable to find matching timescale when doing TFHD unboxing. Therefore when parsing MDAT, the default timescale will be used which is 90000. All CC timestamps will then be incorrect.
This also fixes "Shaka Error MEDIA.VIDEO_ERROR (3,,PIPELINE_ERROR_DECODE: Failed to parse H.264 stream)" error when playing DASH MP4 H.264 streams with CEA-608 CC embedded. It's likely that the VDA bundled in Chromium-based browsers have already included EPB detection & prevention. If we let the player to remove the byte, VDA will complain about stream conformance.
Closes#3502
There was an alias to shaka.test.Util in a global context which was
affecting other tests. The result was that these tests could refer to
"Util" without the namespace or their own alias, and everything would
work.
The problem with that is that when the file with the global alias was
removed or disabled, those other tests would fail because "Util" would
be undefined.
This removes the global alias and adds missing local aliases to the
test suites that were accidentally relying on the global one.

This is an MP4 Parser which extracts CEA-708 packets from Fragmented MP4 streams.
The Closed Caption Parser (shaka.media.ClosedCaptionParser) will own this MP4 Parser, and will initialize it and call it as shown. As data comes in, the parser will parse this data, and the caption packets data then be returned in a callback (on708Data), as shown. Here, a theoretical decoder (future pull request, mentioned as a Todo comment) will decode and extract the parsed captions from these packets.
