Adding the count of channels, as a new field for tracks and streams.
Used for HLS audio tracks.
Resolves#826.

This change is to expose an audio track's role in order to differentiate
among a main / caption / commentary track that shares the same
language.

This adds a method on Player to get the license expiration times for
the current EME sessions. This also adds the expiration times to the
stored content structure for offline content. This will update the
stored expiration while playing content (e.g. license duration changes
when playback starts).
Closes#727

Rather than having it in the DashParser as a network response filter,
we should have it in StreamingEngine. This will give it access to the
segment times so we can calculate the presentation times for the event.
Otherwise, there is no way to know when the event should actually occur
since the app can't know which segment is being downloaded or which it
came from.
This also adds startTime and endTime fields to the event so the app
doesn't have to calculate them. For reverse compatibility, the old
fields will still exist.
Closes#698

To better support alternate storage mechanisms, this change abstracts
shaka.offline.DBEngine into an interface called
shaka.offline.IStorageEngine.
DBEngine has been changed to implement this interface, and allows the
addition of implementations that do not use IndexedDB.

Add UI options to select current audio and text language.
Split selectTrack() into selectText() and selectVariant().
Stop automatically disabling ABR manager when a variant is selected.
Add a warning if selectVariant() is called while abr is enabled.

Parses DASH trick mode tracks and puts the extra trick mode Stream
into the manifest. StreamingEngine can now use this info to optimize
streaming during trick play mode.
Includes:
- a new demo asset with a trick mode track
- updates to tests (we now require at least one audio or video stream
and we require bandwidth attributes on them)
- updates to the parser's trickmode test
- a new StreamingEngine test

If a key status is 'output-restricted', treat the key as unusable.
In many cases it is, and we have no way of differentiating when it is
or is not. So our treatment of this status should be conservative,
and we should treat the key as unusable. This will prevent
HDCP-related failures that may be caused by adapting to a stream whose
output restrictions may not be met. The hasOutputRestrictions flag on
streams and tracks is now gone.
The caveat to this change is that if content is encoded with the same
key for SD and HD, and HD streams have HDCP restrictions that cannot
be met, we will now consider both the SD and HD streams to be
unplayable, even though we could still play the SD streams. Because
we can't separate the status of the two streams, we don't know for
sure if the SD streams can be played.
We will no longer support such content due to the complexity of doing
so, and due to the risk of playback failures on adaptation to
restricted streams. Streams with different security requirements
should always be encrypted with different keys. Content which does
not follow this best practice will no longer be playable in Shaka
without modifying the player.

Added new offline_utils.js to hold utility methods for offline
support. This also removes a circular dependency between
Storage and DownloadManager.
