After looking into the speeds for removing data from IndexedDB, it was
found that using a cursor was slower than the other methods. This change
takes the remove logic and changes it to remove each key as part of
one transaction.

Now DownloadManager will handle the storing of the media segments.
This will make it easier for forks to handle download/storing segments
using background features (e.g. service workers).

The bulk of the logic for gap jumping is handled in Playhead. It
tracks the current buffered ranges and jumps over any gaps that appear.
It listens for a special browser event ('waiting') for when the video
element runs out of playable frames.
This change also removes the logic for jumping gaps at the beginning
of the timeline. This is handled by the more general gap jumping
logic and works cross-browser.
Finally, this updates the buffering logic to only count the amount of
content buffered (i.e. ignoring the gaps). This fixes some bugs where
gaps in the content can result in StreamingEngine buffering forever
since it thinks only a little is buffered.
This includes full implementation of the logic, but this doesn't close
the issue since there aren't any integration tests yet. Those will
be added next.

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

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).

By default, we will now store all text tracks, regardless preferences.
This not only helps with our demo, but makes sense for applications
that have not bothered to configure the track callback for offline
storage.
This also fixes bugs in the default track selection algorithm,
changes the default audio track selection to fall back on primary
variants in cases where the audio language preference cannot be met,
and adds tests for the default selection algorithm to verify correct
behavior.

There was a bug where Storage would always store every track,
independent of what was chosen. This fixes it and adds a test so this
doesn't happen again.
This also updates the ManifestParser API usage Storage. It was
updated in 2ca962a3 and Storage was not updated.

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.

This bans the use of Array and String methods introduced in ES6.
These are not implemented in IE11, so their use is not allowed.
This also replaces our recently-introduced use of these methods to
fix test failures on IE11.

Behavior for IPR streams:
* offline storage disallowed
* segment references will not be stretched to the period
* seek range starts at 0
* seek range end is calculated like the live edge
* seek bar is from 0 to duration, not the seek range

stored content.

Original Chromecast devices can output a max of 1080p, and may have
issues digesting higher resolution content. Since higher resolution
content would be downscaled for display anyway, limit Chromecast to
1080p to avoid both decoder issues and wasted bandwidth.
Some Cast devices may support UHD content, but the max res for
Chromecast is currently hard-coded until we have a way to detect a
device's capabilities at runtime.

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

Now the demo assets can only be stored once, if an asset is stored
the store button will disable. Combined the store and delete buttons
into one. Added a text box to set the name of the asset when
storing custom assets. Also add export to Storage.destroy so it
works in the compiled version.

* Remove warnings for incorrect argument counts in configure.
* Duration incorrect for multi-Period.
* Multi-Period does not always work with multi-codec.
* Progress meter visible from start and after done.

Now the Storage class can store protected content and play it back.
When deleting it, the offline EME sessions will be removed. Also
now offline support appears in Player.support().

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.
