This also cleans up compiler errors for:
- Things required but not used
- Things used but not required
- Write-only local variables
We are suppressing the 'unnecessaryCasts' error in specific places
where it is, in fact, necessary to convert between unrelated types
for polyfills and work-alikes.

This error type will be used for all internal errors, and will rely
on numeric error codes which can be easily checked by the application.
This also changes PSSH parsing to throw on errors instead of retaining
partial data.

This changes namespace exports to the more targetted exportDoc,
adds exports where they are needed and removes them where they are
not. Exporting of Uint8Array and String utils should be re-evaluated
later.

The init segment for WebM can specify a Segment element of an unknown
size. This means that the segment should take up the remainder of
the data.

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.

* 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.
Change-Id: I2e9272db680cba7ecc4613d97f1d3a94ac2244cc
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.

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.

Issue #160
Change-Id: Ife0814deb65715923a572b45880137a99b378035
The final chunk was only being stored when the endTime of the final
segment happened to be null. An index with explicit end times for
all segments, even on one stream, would trigger this bug.
For example, the end time of the final video segment may be null, but
the end time of the final audio segment may be equal to the content
duration. The stored audio would be missing a chunk, causing the
computed stream limit to be too short on playback.
This corrects the off-by-one error in the storage code by explicitly
signalling when a segment is the last one, rather than checking for
a null endTime.

Add new ContentProtection interpretation API that allows applications to
return multiple DRM configurations for each ContentProtection element
and to parse raw ContentProtection XML elements.
This patch deprecates DrmSchemeInfo in favor of DrmInfo. Furthermore,
DrmSchemeInfo will be removed post v1.5.0.
* Replace DrmSchemeInfo with DrmInfo.
* Move Restrictions class definition into its own file.
* Populate initData values from explicit PSSHs without application
intervention.
* Allow explicit PSSHs to differ between Representations

Added a new class called FailoverUri which handles multiple URLs and
switches to others when one fails. This is also handles the request
itself. This replaces SegmentMetadata as well as a number of manual
requests.
The MPD parser now produces arrays of URIs rather than just one. The
MPD Processor then converts it to a FailoverUri inside the manifest.
Added unit tests to test the new functionality and updated the old ones
to the new changes.
This does not support failover on subtitles since subtitles are handled
by the browser.

The circular dependency,
ContentDatabase -> RangeRequest -> AjaxRequest -> ContentDatabase,
causes issues for the upstream Closure compiler. This patch breaks that
cycle by factoring out reading and writing operations from ContentDatabase
into ContentDatabaseReader and ContentDatabaseWriter respectively.
The following minor changes have been made to code that has moved:
* Removed retrieveInitSegment() since it's not used.
* Changed .stream_ids to ['stream_ids'] in retriveGroup().
* Reworked deleteGroup() so that it doesn't depend on retrieveGroup().
* Made deleteStream() private.
* Made minor formatting changes to meet the 80 character limit.

* Add a URL override and an HTTP method override to LicenseRequestInfo.
* Use LicenseRequestInfo objects as dictionaries so the pre-processor
interface works like the Player.configure() interface.

* Improve pre-processor integration test.
* Add @expose to some typedefs so they are included in the documentation.
