This makes progress callbacks into a required parameter on all network
scheme plugins. This does not mean that every plugin must make use of
the callback, but every caller must supply the callback.
In production, NetworkingEngine already supplies this callback
universally, so our HTTP plugins make use of it whenever progress data
is available.
Our tests, however, did not always supply this callback, leading to
test failures. These failures were more likely to show up in Jasmine
3 than Jasmine 2 for some reason, which caused us to downgrade back to
Jasmine 2 recently.
By making the callback required, we can clean up this inconsistency
between test and production and give the HTTP plugins what they expect
in all cases.

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.

The numBytesRemainingObj parameter in |NetworkingEngine.send_| was
optional, but in some circumstances we were assuming that it was set.
This just changes the parameter to be non-optional.
In fact, the parameter now being non-optional revealed an error that
caused the numBytesRemainingObj to be lost on network retry.

This is an automated change to convert use of "function" functions
to arrow functions. This doesn't change all uses of bind() that
could be converted. This also doesn't remove all "function" functions.

We get an error from ReadableStream when we abort a request. This
causes uncaught rejection error logs in Chrome. This ignores the
error and stops the logs.

When the network becomes slow, we check if stopping the current request
and download the content with lower resolution is faster. If so, abort
the current request and start a new one.

This CL limits the use of |setTimeout| by wrapping it in our own timer
class. The timer class makes it easier to track and cancel time-based
events.
To ensure that|setTimeout| is not used outside of our timer classes, the
conformance rules have been updated to only allow |setTimeout| to be
used by our timer classes.
Since |setTimeout| is very similar to |setInterval|, the conformance
rules for |setInternal| rules were updates to reflect more of the logic
behind why we don't want to use |setTimeout| and |setInterval| directly.

This integrates the deprecation tool with our library and updates
all the deprecated warnings to use our new tool.
As some features needed to be removed in 2.5, this change removes them
since their deprecation checks would make us fail.

If we use sets for filters in networking engine we get some
pretty good additions:
1. Someone can't double-register their listener (by accident)
2. We don't need ArrayUtils to remove listeners.

On Edge, window.ReadableStream exists, but attempting to call it
results in an error.
This changes the support check for Fetch to try actually creating a
ReadableStream before it OKs using Fetch.

In a recent CL, the Http Fetch plugin was modified to make use of
ReadableStream. However, ReadableStream isn't available on every
platform. This change modifies the Fetch plugin to not be used if
ReadableStream isn't defined.
This also adds a basic mock ReadableStream for tests.

This is part 1 of conditionally aborting requests when network
downgrading.
1. Add progress event handler for Http XHR Plugin, to get more frequent
updates for network bandwidth estimate and suggest streams based on
that.
2. When the plugin doesn't support progress event, call
onProgressUpdated function after every segment is downloaded.
3. Replace onSegmentDownloaded with onProgressUpdated function in
player.js and network_engine.js.
4. Since XHR Plugin supports progress event while Fetch doesn't, change
the config to prefer XHR over Fetch API.

There is now a separate server URL for 'individualization-request'
messages; if it isn't given, it will fallback to the license server.
There is also a new field in the Request object so a request filter
can act differently based on the message type.

a retry.

Previously, HttpFetchPlugin would treat any non-Shaka error as
HTTP_ERROR when there were potentially other circumstances which
could have produced a non-Shaka error.
This change catches errors from fetch sooner, so that there is no
need to do a fuzzy check for error.severity. It also clears the
request timeout regardless of whether fetch throws or not.
Closes#1519
cloneObject used to be part of config_utils.js.
This meant that a number of classes that didn't actually use
config objects required ConfigUtils.
This moves cloneObject into the new ObjectUtils, to clarify that.

This makes a large number of small typo fixes. It also rewords a
number of comments and JSDoc descriptions, and does some
formatting standardization.
This doesn't fix every single issue, but it fixes a lot. Notably,
there were some formatting issues I declined to standardize due to
ambivalence on what the proper standardization would be; for example,
when and where empty lines should show up in JSDoc.

This is part of a change to convert all usages of 'var' with either
'let' or 'const'. This takes a conservative approach for 'const' where
it will only be used for aliases and storing the "original" values in
tests.

Fetch requests with a method of GET or HEADER cannot have a body, or
else the request will fail. Normally we had no problems with this, but
it turns out that Edge counts a body of 'null' as being defined.
This changes the Fetch scheme plugin so that it will replace null with
undefined for the body in the init data.
This also makes it so that HTTP_ERROR errors emitted by the http
plugin will include the original error, to aid in debugging future
issues.

This plugin is preferred over the XHR plugin, if available.
This plugin requires AbortController, which is only present on
Firefox 57 and Edge 16, so this will not be active on every platform.
This also adds a simple mock for the Fetch API for use with Jasmine.

When changing networking engine to use AbortableOperation, we had an
accidental regression. Now, when it runs out of retries, it rejects
with an error of "undefined" instead of with the actual error that was
causing it to retry.
This changes networking engine to save the last error and return with
that. It also modifies the unit tests to catch this problem.
Closes#1278

This uses AbortableOperation in all networking, from the scheme
plugins all the way to the request interface.
This also updates all default scheme plugins, docs, and sample code.
Backward compatibility is provided for scheme plugins and the
request API in NetworkingEngine. This compatibility will be
removed in v2.5.
Two cancelation-related tests have been disabled in
player_integration until the new abort interface has been adopted
in the manifest parsers.

Once we start moving to ES6, uncompiled mode stops working on non-ES6
browsers (IE11 is the only one we test on). We can disable uncompiled
mode in the demo, but we still want our tests to be uncompiled. With
uncompiled library & tests, we can test units that are not exported
and even access private members that would otherwise be renamed.
For production/demo, Babel plays no role. The Closure Compiler will
take in ES6 and spit out ES3 syntax (even older than ES5, so we can
at least run & fail a support check).
Babel will be used by Karma to preprocess all test and library code
before serving it from Karma. This will allow us to use ES6 in both
the library and the tests, and still run uncompiled tests and test the
uncompiled library on ES5 browsers such as IE 11.

This adds the ability to supply an isCanceled() callback when making a
backoff object. If the callback is provided, the backoff will break the
timeout into a series of 200 MS timeouts, and check isCanceled() between
every segment.
This changes makes it so that, when canceling a load, you can quickly end
the current backoff. This will making canceling a load significantly faster,
especially if the player is on a late retry.
This still does not quite fix issue #1084 to my satisfaction; if the
manifest is currently downloading, the cancel will need to wait on that.
Canceling an in-progress manifest download will be yet another followup CL.
