This will help with porting to IE11. Chrome, Firefox, Safari, and
Edge all have native Promises.
This polyfill does not support thenables because Shaka does not use
them. Other than tests related to thenables, this polyfill passes
the A+ test suite.
It is also worth noting that this polyfill is incompatible with
native Promises, so it should not be used to replace a native
implementation or mixed with browser APIs that may use a native
implementation internally.
To safely test in Chrome, force prefixed EME (to avoid native
Promises), set window.Promise to null, then load some content in
the test app. If using a verison of Chrome after prefixed EME
was dropped, use unencrypted content.
To run the A+ test suite, compile the library, install nodejs and the
module 'promises-aplus-tests', then run ./test_promise_polyfill.js.

These keys cannot always be used as keys, for example on IE11 where
very large init datas are found in PlayReady content. Since there
should not be a large number of unique init datas, a linear
suppression pass and a quadratic removeDuplicates should not be a
problem in practice.

* Supports live streams of a fixed length.
* Live streams that stop now correctly end the video.
* Only uses local MPD when @availabilityStartTime is in the future.
* Added configuration option liveStreamEndTimeout.
A live stream is considered "ended" when the play-head moves past
the last segment for liveStreamEndTimeout amount of time. This allows
the MPD to be updated with new segments.

end up in different StreamSetInfos.

AdaptationSets has their main flag set (commit

* Fire an error event when all audio/video tracks are restricted
during playback.
* Fire an error event and fail gracefully when all audio/video tracks
are restricted before playback (requires calling player.unload() when
the VideoSource's attach promise gets rejected).
* Rework AbrManager so that getInitialVideoTrack() can be called before
starting bandwidth monitoring.

Some versions of the compiler do not seem to recognize this as
unreachable, so add a return to satisfy the compiler and silence
the warning.

* Updates all Copyright years to 2015.
* Adds licenses annotations to all JS.
* Makes all licenses identical to avoid repeated appearance in the
compiled output.
* Drops fileoverview annotations, which do not affect docs output.
* The linter still requires fileoverview on externs.
This patch required a newer closure compiler, since the previous
version we used had a bug regarding license annotations that caused
the license comment block to appear in the output once per file
regardless of uniqueness.

This reverts commit 8cb24652cb, due to
the fact that the new annotations caused our binary size to jump
by 52%.
The compiler preserves all 'unique' licenses, which causes trouble
since the comment blocks with the license annotations are not unique
and contain file overview comments as well.
We can re-examine this once we have restructured the license headers.

If a session becomes "ready" more than once, there is a race where
it can wind up in the database multiple times. This eliminates
duplicate session IDs on both load and store, which avoids an
"unexpected completion" error from Chrome's EME implementation.

The trackschanged event fires when restrictions are updated
so in order to quickly apply restrictions when network
conditions are not changing, simple_abr_manager listens
for this event and selects a new track if required.
This extends the work started in 97769bd, where we missed points
of failure in EmeManager.

The underflow threshold was too small (measured 0.13s buffered during
underflow), and the minBufferTime was unnecessarily large.

There was a static method on OfflineVideoSource which forced the
compiler to keep ContentDatabase in the build.
This fix increases the savings for a no-offline build from 488 bytes
to 9592 bytes, an increase in savings of 19.6x.

This introduces a new method on PublicPromise called destroy(),
which does for Promises what destroy() does for the other classes:
shuts down async processes and cleans up references.
In addition to catching errors and shutting down more cleanly in a
wider array of circumstances, this may also help with GC, since we
no longer leave pending Promises around with handlers attached to
them.

Use 'keystatuseschange' events from EME together with cenc:default_KID
from the MPD so StreamVideoSource can determine if the key system
can/will decrypt a stream before it attempts to play it. This enables
the Player to safely (and automatically) switch between streams that
are encrypted with different keys.
Support AdaptationSet @group, which is the preferred approach to safely
use multiple encryption keys over multiple Representations.
* Squash AdaptationSets from the same group into one StreamSetInfo.
This enables support for @group without introducing special case code
into StreamVideoSource and EmeManager.
* Fire 'trackchanged' events when tracks becomes available/unavailable
either from application restrictions or key status changes.
* Pull key IDs out of DrmInfo and put them into StreamInfo so key status
changes can drive per stream availability instead of per StreamSet
(AdaptationSet) availability.
