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.

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.

just fetch the segment before the one needed.
* Handle missing segments by polling instead of failing right away.

Now there will be an error if the wrong keys are retrieved from the
license server. This can happen if the manifest is incorrect or if
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.

We now avoid tricky things like CustomEvent and setting properties on
native Events. This gives us better cross-browser compatibility and
less complexity.

Each category now has its own range of 1000 error codes. Using codes
in the thousands rather than the hundreds will help avoid confusion
between our error codes and HTTP error codes.

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.

* Replace onBufferNewPeriod() with onChooseStreams().
* Remove newPeriod()
* When transitioning Periods, only call onChooseStreams(p) once
Period p has been setup.
* Refactor documentation.

* Tidy up unit tests, and add more eviction tests and drift tests.
* Add integration tests.
* Handle end-of-stream and end-of-Period scenarios when segments
are not perfectly aligned to Period boundaries.
* Use segment receipts to determine which segment to buffer next.
* 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.

and evicts old segments as it appends new ones.

This also cleans up compiler errors for:
- Things required but not used
- Things used but not required
- Write-only local variables
We are suppressing the 'unnecessaryCasts' error in specific places
where it is, in fact, necessary to convert between unrelated types
for polyfills and work-alikes.

This error type will be used for all internal errors, and will rely
on numeric error codes which can be easily checked by the application.
This also changes PSSH parsing to throw on errors instead of retaining
partial data.
