Now the Storage class can store protected content and play it back.
When deleting it, the offline EME sessions will be removed. Also
now offline support appears in Player.support().
Closes#343

This contains two major parts: the Storage class, which manages
storing, listing, and deleting the stored content, and the offline
manifest parser, which loads the stored content into a manifest so the
Player can play it.
This does not include support for storing encrypted content. The
EME sessions will not be stored properly and will fail to play.

This adds a new abstraction to cancel simple Promise chains.
It is intended to help resolve load/unload/destroy issues. At this
time, only player.load() is cancelable, and only by destroy(),
unload(), or other calls to load().

Before, the same error was used for no available configurations or

different errors. Also elaborated on the error in the documentation.

out incompatible codecs.

This is part of the v2 equivalent of the ContentDatabase. This only
manages low-level interactions with the IndexedDB and wraps all
actions in Promises.
This also adds an in-memory version that is used for testing.

Before, Player.configure would check the number of arguments for
the functions being set and reject those with an incorrect count.
However, this does not work with jasmine spies. So instead allow
it but log a warning.

* Set this.parser_ to the correct property in load()

MediaSource may throw QuotaExceededError if it cannot append a
segment. Now, StreamingEngine will catch these errors from
MediaSourceEngine and reduce the buffering goals to avoid
encountering additional errors.

If a key is output-restricted it may still be usable.
So, instead of disabling these tracks, indicate that they
may be playable.

This moves a bunch of code out of Player into different files. This
is needed to allow the new Storage class to have the same behavior
as Player. This also reduces the size of player.js.
This moves the following code:
* Determining the manifest parser to use.
* Period filtering.
* Application track restrictions.
* Configuration object merging.
* Choosing initial stream sets.
* Track creation.
Change-Id: I84d68d39b487447d6f8d61a145cd034a88165739
Now when using deferred switches in Player, it will track whether
to clear the buffer. This is needed because during startup,
StreamingEngine will append the first media segment; the old code
assumes that the buffer is empty. This is especially important for
text tracks which may only be one segment.

Because we were using Function.apply to create strings, large arrays
were causing problems with browser argument count limits. This
now splits the arrays up before calling.

Change-Id: Ic94a950997e2f17563ecba8fb628f62c0ed18fc2
Now the application can restrict the kinds of tracks that the Player
will play. This is done through player.configure(). This also
allows restricting the playable tracks based on the EME key status.

the license server returns the wrong keys.

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

This also changes DrmEngine to reject key systems that do not have
any license servers, this causes init() to fail.

The receipt buffer mechanism allowed us use byte-based
eviction; however, it increased the complexity of StreamingEngine
and required us to make strict assumptions about the manifest.
With the receipt buffer gone, we will now do time-based eviction.
Applications can specify a maximum "buffer tail" length instead of a
maximum byte limit.

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

* Handle drift with eviction and other drift corner cases.
* Handle additional errors and improve overall robustness.

This also changes from using Node types to using Element types. This
is more correct since the code only deals with XML elements and not
with other Node types (e.g. text content nodes).

Non-nullability on some types forces us to use casts everywhere, at
which point the compiler is just trusting us. So they might as well
be nullable and save us some typing.
Also, change HTMLVideoElement to the more general HTMLMediaElement.
