This corrects/normalizes license headers in misc. files, such as
config files, docs, build tools, tests, and externs. This does not
affect the compiled output, and is only done for consistency.

Period-flattening will concatenate Stream objects, so this information
should be available per-Stream instead of at the Variant level.

This removes periods from the internal manifest structure and cleans
up code and tests accordingly. This leaves us unable to play
multi-period DASH & offline streams until the main period-flattening
algorithm is completed in shaka.util.Periods.
Three test cases have been disabled for the moment.
Multi-period playback will be restored in a smaller, more focused
follow-up commit, with disabled tests re-enabled.

This could help test failures on Windows since the video doesn't start
playing after the 5 seconds. If it fails, we'll also get more
debug information for it.

This changes the eslint rule to enforce a strict pattern for the
argument comments. The comment must appear before the argument and
must be /* foo= */. This still ignores line comments.

This method should probably never have been in the library, since it
creates a fixed-sized, muted element.

This reflects changes in Google's policy on JavaScript license
headers, which should be smaller to avoid increasing the size of the
binary unnecessarily.
This also updates the company name from "Google, Inc" to "Google LLC".

This allows us to avoid suppressing the indentation rules and ensures
we have correct indentation. It also makes it harder to make mistakes
since the variables are only accessible within the callback and you
can't accidentally contaminate another object with an incorrect call.

This add a filterDescribe that can be used to filter groups of tests
based on platform support. This consolidates the different test
filtering to one place.

This is a fully automated change. The linter will fail because the
extra indentation caused line-length errors. These won't be fixed
automatically. They are fixed in a follow-up to make this one fully
automated.

With the new style rule, we cannot have two statements on the same line.
So we can no longer have an "if" on a single line and we cannot have
an arrow function with a body on the same line as when it is used.
This is mostly a manual change.

We use custom indentation for the ManifestGenerator to make the repeated
calls easier to read. This disables the coming linter rule for these
blocks of code. This also goes through and unifies the formatting. The
indentation should be 4 spaces from the left side.

Refactored |StreamUtils.getAllVariants| to get variants from a collection
of periods (rather than a manifest). This allows us to avoid needing to
assert that the manifest exists (when we know it will).
Looking long-term, as part of the refactor the method was moved to a
period-focused utility class. The goal of this is to make it easier to
see what methods may go away when we flatten periods.

Before, media source engine could be created with no text displayer.
However, player would always create media source engine with a
text displayer.
Just like with closed captions, this appeared to be a good time
to change it to be passed in the constructor and have media source
engine own it.
This now means that media source engine is responsible for destroying
it - lessening player's responsibilities.

We often use the IDestroyable interface to provide us with a standardized
way to break internal references and tear-down objects, however many
objects don't need this to be async. Once using IDestroyable, everyone
must assume that you must be async.
This change introduces IReleasable, a sibling to IDestryable, which
provides the |release| method. IReleasable is the synchronous version of
IDestroyable.
This change converts EventManager from IDestroyable to IReleasable as
the first of many conversions.

Instead of duplicating the default configuration values in each test,
this now uses the default configuration methods.

Instead of requiring media source engine to create its own closed
caption parser and then allow tests to override it, have it be
passed into the constructor.
This allows us to easily use the fake one in all our tests and
removes the need for a test only method on media source engine.

Adding support for CEA closed captions embedded in video streams for
Dash.
1. Dash parser reads and parses closed captions' channel and language
information.
2. Player creates text streams for the closed captions.
3. Media Source Engine calls mux.js Caption Parser API to get the closed
captions embedded in the video streams.
4. Text Engine stores the closed captions, and text displayer shows the
captions.
TODO:
1. Add test cases, will send out another CL.
2. Change closed captions support for hls to the similar way we handle
dash closed captions, will send out another CL.
3. Handle dash content that's missing language indication from the manifest.

First, we cannot destroy the EventListener in MediaSourceEngine until
the in-progress tasks are done so we can get the 'updateend' event.
Second, we shouldn't detach MediaSource until the tasks are done to
ensure the media stack is still working.
As part of that, we need to delay the destruction of DrmEngine to
ensure it happens after MediaSourceEngine.

Before, we would need to pass a manifest to DrmEngine to initialize
it. This was a problem as we look to support playback via src=.
When looking at how DrmEngine used the manifest, it appears to just be
a simple way to pass in the variants and the offline session ids. By
changing DrmEngine to accept the variants and offline sessions ids, we
can break the association between DrmEngine and Manifest.

There are two intents when we initialize Drm Engine and the meaning
of the parameters are nuances depending on what you are trying
to do.
This change creates two different initializing methods so that
initializing drm engine for the intended purpose can be more
clear.
With this, some internal naming was change to better reflect how
some variables were being used to give them a bit more context.

Our support for CEA 708 closed captions only works if the container
video file is transmuxed. Because of that, we were not successfully
reading such captions on platforms with native TS support.
This change adds a configuration option to force TS to be transmuxed
even when unnecessary, to account for that situation.
It also adds an integration test to ensure that CEA 708 captions can
be extracted on every platform.

This is part of a change to convert all usages of 'var' with either

it will only be used for aliases and storing the "original" values in

This replaces checkWhatever type functions, which are called at the
start of a test, with checkAndRun functions, which are a wrapper
around the test method. This change standardizes our tests, since
checkAndRun functions are used in the db engine tests but not
elsewhere.

This change:
- Fixes the use of temporary licenses with manifests without init data
- Re-enables an integration test which was accidentally disabled
- Makes that test use a manifest without init data, to cover #1159
- Makes the test less flaky
- Reduces the minBufferTime of offline manifests, which both speeds
up load of offline content and makes the test faster / less flaky

This change enables an additional conformance check in the compiler
which prevents us from committing code where the compiler fails to
infer what "this" means.
None of these changes constituted actual bugs, just inference failures
in the compiler.

Some platforms (such as Chromecast) support extra MIME parameters like
framerate, bitrate, width, height, and channels. Since other
platforms will ignore these extra parameters, we should always query
using these parameters.
This introduces the framework to construct these "extended" MIME types
from Stream objects. Extra parameters for other platforms can easily
be added later.

This is part of adding a new conformance rule to add additional type
safety. This will disallow using properties of unknown types or using
unknown properties.
The first parts will be fixing errors caused by the new rule. These
are backwards compatible, so can be applied before the rule is enabled.
Once all the errors and bugs are fixed, the rule will be enabled.
Change-Id: I48335fc6659d3c33a6d55b00d087b59410c79cf7
The old definition using a union with a Function causes problems. The
compiler tends to treat this as an unknown type, so we loose type
safety. The new types ensure full type safety, at the cost of needing
to "convert" the spy when it is used as a function.

Our EME polyfills give a key status with a Key ID of '00' (a single 0
byte). This breaks the Player logic for restricted tracks since it
assumes that those are not playable. When we get this Key ID, we should
treat the key status as a global status, not for that specific Key ID.

The text parsers were all stateless. This caused problems with MP4
VTT as the timescale is needed later on for other boxes. This changes
parsers to carry state.
How time is referenced with the text parsers is not clear and has
caused confusion. In v2.0.1, we introduced the useRelativeCueTimestamps
option to control the behavior of our WebVTT parser. We decided in #480
(comment) that we would remove this option in v2.1.0. All WebVTT
timestamps in v2.1.0 will be relative to the segment time. This change
creates a new time context interface that will be used to help limit
the confusion around how time is communicated.

This adds a method on Player to get the license expiration times for
