* 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.

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.

Make the Player exit the buffering state when the minimum
buffering goal between all Streams has been reached.

* Make IStream more precise by adding more documentation.
* Make misc. docs related to Stream more consistent.
* Remove |minBufferTime| from IStream; use a configuration
option instead.

For static content, if the playhead moves to the end of the video then
either the video should pause or loop. Before this patch media timeline
misalignment and buffering detection would sometimes prohibit this from
happening.
* Ensure the MediaSource's duration is >= the end of each
stream's last segment (both before and after timestamp correction).
* Use an append window to keep the MediaSource's duration constant.
* Rework Stream startup so that the MediaSource can be modified
safely during timestamp correction.
* Remove timestamp correction member variables from StreamVideoSource.
* Fix buffering detection when there are no buffered ranges.
* Add sanity checks and improve logging for debugging MSE issues.
* Improve Stream startup documentation.
Closes#155
Change-Id: I6f7a1d15240af62a2282f3f62b29cd3acd5b1873
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.
Closes#68

* Move seek range updates into SegmentIndex implementations
and StreamVideoSource.
* Remove unnecessary sub-class hooks from StreamVideoSource.
* Remove internal LiveSegmentIndex timer: do SegmentReference eviction
and generation on demand.
* Rework Stream startup again: consider Streams as started when they
have buffered some minimum amount of content. As part of this, only
apply a timestamp correction to the SBM when the streams have started.
* Defer stream switches until all SegmentIndexes have been corrected.
* Partially revert optimistic "bufferedAhead" calculations in Stream:
check if we've buffered enough content at least every second.
* Make LiveSegmentIndex more robust against a "wrong"
@availabilityStartTime.
* Fix a bug where a positive timestamp correction would trigger an extra
Stream resync.
* Fix a bug in evict_() where the first segment would never get evicted.
* Check stream started conditions in onUpdate_ instead of after a segment
has been inserted.
* Tidy-up immediate/clearBuffer naming and other comments.

* Allow segments from different streams (Representations) to coexist
in buffer.
* Only fetch a single segment at a time.
* Remove id field from SegmentReference and remove SegmentRange.
* Only start the Streams once the buffer is "full".
* Stop DashVideoSource from triggering an extra resync during startup.
* Make Task.abort call order deterministic.
A follow-up patch is required to handle certain seek patterns in
live streams.
Issue #51
Change-Id: Ib7c9021471f1ed89323f19764463202b119cb491
This patch reworks SegmentIndexes so that any SegmentReference they
contain is guaranteed to be available. This makes SegmentIndexes work
consistently between static content and live content (specifically
content specified using SegmentTemplate with @duration).
* Rework StreamInfo to use a ISegmentIndexSource and a ISegmentInitSource,
which construct a SegmentIndex and an intiailization segment
respectively.
* Make ManifestInfo destructible and various async operations in
StreamVideoSource safer.
* Introduce LiveSegmentIndex, which manages SegmentReference eviction.
* Introduce DynamicLiveSegmentIndex, which manages SegmentReference
eviction and generation.
* Implement improved segment availability logic for segment eviction.
* Move SegmentIndex construction from MpdProcessor to several
ISegmentIndexSource implementations.
* Use a SegmentIndex to represent subtitles to simplify Stream creation
in StreamVideoSource.
* Move manifest update code from StreamVideoSource to ManifestUpdater.
* Move PeriodInfo.duration determination in MpdProcessor to StreamVideoSource.
* Since "forced" manifest updates are no longer required for content
specified using SegmentTemplate with @duration, simplify manifest update
code in DashVideoSource.
* Make Stream continue to update even if it runs out of
SegmentReferences, this simplifies previous resync logic and makes
DynamicLiveSegmentIndex work seamlessly.
* Refactor SegmentIndex and initialization fetch code in ContentDatabase.
* Download all SegmentIndexes in the background after the initial streams
have started.
Follow up work is required to remove seek range logic from
DashVideoSource.

Strip extraneous minBufferTime copies.
Default minBufferTime in MpdProcessor if missing.
Pass minBufferTime as a parameter to Stream.start().
Keep a buffering goal separate from minBufferTime, which will only
be used for stream startup (as intended by the DASH spec).
This allows us to startup quickly and still buffer ahead.
Relates to #51.

* After updating a manifest restart any streams that failed
to initially start.
* Seek to the stream start time only after the streams have been
initialized, seeking before can cause lock-ups with MSE.
* Rename 'bestStartTime' to 'currentSegmentStartTime'.
Issue #21
Change-Id: Ibad91fe2d5171196e93f20961008cdd25ecc437e
* Move internal non-DASH specific code into the 'media' namespace.
* Remove DASH references from generic stream code.
The documentation is not changed as a follow-up patch will factor out
DASH functionality from StreamVideoSource back into a new
DashVideoSource class.
