This is part of adding a new conformance rule to add additional type
safety. This will disallow using properties of unknown types or using
unknown properties.
The first parts will be fixing errors caused by the new rule. These
are backwards compatible, so can be applied before the rule is enabled.
Once all the errors and bugs are fixed, the rule will be enabled.

The old definition using a union with a Function causes problems. The
compiler tends to treat this as an unknown type, so we loose type
safety. The new types ensure full type safety, at the cost of needing
to "convert" the spy when it is used as a function.

In DASH, when parsing a date, it should default to UTC. When we pass
the date string to Date.parse(), it will use the local timezone. So
if we don't see a timezone, we need to manually add the UTC timezone
so Date.parse() will parse the correct timezone.

If you attempt to load an asset and then the first load fails, then
the second load will hang forever. This was caused by the second load
trying to cancel the first, but the CancelableChain not handling this
case.

This adds a severity field to Error objects. This can be used to
detect whether an error is recoverable. All the same errors are still
reported so the field can be ignored.
There are two possible values:
* RECOVERABLE means that the Player will try to recover from the error
* CRITICAL means the Player will be unable to continue and must call
load() again

When defining a box, the box would be defined as a four

In many places we tried to guess the encoding of a piece of text.
This guess fails for Chinese UTF-8 text, and probably text in many
other languages.
However, DASH manifests, TTML files, WebVTT files, and VTTC box
payloads are all specified to be in UTF-8. Rather than guess and
possibly fail, treat all text in these contexts as UTF-8.

Instead of filling the URI templates when parsing the manifest,
wait until the request is made to fill it. This reduces the time
it takes to parse the manifest.
This was tested using a stream with a 24-hour timeShiftBufferDepth.

parse time was about 1 second before, now it is about 200ms.

Before, we did not use suggestedPresentationDelay in the seek range.
This meant that seeking to the live edge would usually lead to a
buffering state because the seek range is the same as the availability
window. Now the seek range is handled differently from the
availability window.

This contains two major parts: the Storage class, which manages
storing, listing, and deleting the stored content, and the offline
manifest parser, which loads the stored content into a manifest so the
Player can play it.
This does not include support for storing encrypted content. The
EME sessions will not be stored properly and will fail to play.

player.load() now uses our new CancelableChain abstraction for its
chain of events. player.unload() and player.destroy() will both
cancel that chain. player.unload() will wait on the cancelation to
complete before resetting the streaming system, to avoid a race.

Some browsers, such as Edge 13, do not report capabilities at all.
Not all encrypted streams have known key IDs, so we should not
use that as a predicate for the encrypted content type filter.
Since not all content has both audio and video, the requested and
reported capabilities may not have both either. So we should
default capabilities to empty lists if missing.
This also adds an encrypted audio-only asset so that audio-only is
covered by our integration tests.

* Permit non-zero presentation start times for VOD: some
presentations have segments which start too far from 0 to
allow the video element to begin playback; now the player will
start VOD presentations from the start of the first segment.
However, segments of the 2nd, 3rd, 4th, etc., Period of a
multi-Period presentation must still start close to 0 (the
player will not jump any gaps in the presentation).
* Prohibit seeking to regions at the beginning of the segment
availability window if segment information is missing from
that region: sometimes live manifests do not contain all the
segments in the segment availability window; now the player
will prohibit seeking to these regions.
* Update definition of live in DashParser to match Player and
Playhead.
* Simplify PresentationTimeline's constructor by just using setter
