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

Widevine HLS manifests have a data URI that needs to be parsed to
generate DrmInfo. Rather than write another parser, factor the data
URI networking plugin to expose the parser to other classes.

This allows network responses to have an X-Shaka-From-Cache header to
indicate that the response was somehow from a cache and should be
ignored for bandwidth calculations. For example, this can be from a
service worker intercepting the request.

This adds a field to the network response that will indicate that the

estimation.

By exporting StringUtils and Uint8ArrayUtils, we can simplify the
process of wrapping, unwrapping, and parsing requests and responses
in NetworkingEngine filters.
This makes it easier to write filters that deal with text-based
data, as it is no longer the job of the application developer to
deal with subtle conversions between string and ArrayBuffer.
We will also fill in requests with defaults if needed. This allows
developers to omit fields when initiating extra requests at the
application level.

In some cases, the networking engine could have attempted to
remove a pending request that did not exist, thus removing other
requests.
Change-Id: I08fb9c11c3dd153af7a148fcb591fe5c0c3634a1
This allows the networking plugins to pass the duration it took for
the request. For example, if a plugin were pre-fetching the segment,
this allows the plugin to tell NetworkingEngine about how long it
really took to download.

The test flake was caused by a leaked instance of Playhead interfering
with NetworkingEngine unit tests. The quickest way to reproduce a
failure on the networking tests was to focus the unit tests for
Playhead and NetworkingEngine and run the suite on IE11.
Playhead tests tear down the Playhead object after each test.
However, one test created two Playheads, effectively leaking one.
That leaked Playhead would continue to poll the fake video element
after the test was complete. Polling used setTimeout.
The NetworkingEngine unit tests would mock setTimeout and show that
the engine was calling it appropriately. However, the leaked Playhead
would also call setTimeout during the NetworkingEngine test, which
would cause an expectation on the number of calls to fail.
The Playhead tests should clean up after themselves, but the
NetworkingEngine tests should not have to mock global setTimeout in
the first place. This change not only fixes the Playhead tests, but
isolates NetworkingEngine's use of setTimeout to a private method
which can be mocked without affecting global state.

This exports all plugins from the library, to make delegating and
subclassing easier for applications.
This also fixes a couple of issues with the generated documentation.

An upcoming compiler release will allow us to generate externs from
exports. Because of that, we are adding some extra exports which are
otherwise not needed at runtime.
- Export properties which implement an interface
- Export classes which are referenced in external APIs
- Export base classes of other exported classes

jsdoc was getting confused and generating, for example, a file called
"shaka.media.html#VttTextParser". Moving the @namespace annotation to
the method itself fixes it.

Without @namespace annotations, static classes do not show up in the
generated API docs. Although I stumbled over one instance while
writing tutorials, the rest were discovered programmatically by:
for x in $(find lib/ -name '*.js'); do
grep -Eq '@(constructor|interface|namespace)' $x || echo $x
done

Using goog.asserts will work with the compiler. So rather than
simply casting a nullable value when passing to a method, we can use
an assert which will correct the type and print a log if it somehow
is null.
This is not the same goog.asserts found in closure library, this
simply calls console.assert, but it is not required to do anything
for the compiler help.

Before, we simply converted each byte from an ArrayBuffer into a
character; however, this is only valid for ASCII characters. This
changes it to fully support UTF-8 encoded network responses.

Some failure scenarios resulted in success on Edge 12.
It seems that calling reject() followed by resolve() in a Promise

Uses location to determine what the scheme should be if unspecified.
This is important because it allows us to use URIs that work for
either HTTP or HTTPS hosted apps without mixed content warnings.
Some special sauce was needed to make it testable, since we generally
can't mock location in tests.

The optional arguments in this convenience function really only help
in the tests. To avoid some component in the library accidentally
making a request with default retry parameters instead of those
configured by the user, I'm making the retry parameters required.
The optional argument for method is only used once. To avoid the
temptation to add more positional arguments for other seldom-used
fields, I'm dropping the method argument completely.

This is important to avoid renaming properties during compilation so
that applications can inject these types without compiling their code.
This also migrates record typedefs to the new documentation format.
Each record will be annotated with 'property' for each field in the
record. This results in better output from jsdoc.

This error type will be used for all internal errors, and will rely
