A previous release note has already noted to use ProgressiveMediaSource
instead of this whole class, so adding a specific release note seems
unnecessary for this one.

- SimpleExoPlayer now always generates a session ID at
construction time. This ID is used indefinitely, including
for tunneling, unless a call to setAudioSessionId is made
to change it.
- DefaultTrackSelector support for enabling tunneling has
been changed to a boolean, since tunneling now uses the
same session ID as non-tunneled mode.
- Since the session ID is now always set at the top level,
internal propagation of generated session IDs is no longer
necessary, and so is removed.

The ExoPlaybackException types are locations from where the exception
is coming from and not the type of exception itself, which should be
denoted by different exception classes.
To avoid a mixture of error types and class checks, the timeout
exceptions should use their own class and be of type RENDERER as this
is where the timeout actually happens.

This allows the respective components to adapt to the speed changes
if desired.
To avoid frequent updates to the media codec operating rate, we also
forward the target speed to the renderers so that this value can be set
based on the target speed and not the current speed.

Catching OOM errors is bad practise unless there is a specific known
cause that tried to allocate a large amount of memory. Without this
known cause with a large allocation, the source of the error is
likely somewhere else in the app and every random small further
allocation may lead to additional OOM errors (for example b/145134199).
We have three known causes in ExoPlayer:
1. Source allocations based on unexpected values in streams. This is
caught on the loader thread and reported as an
UnexpectedLoaderException.
2. Output buffer allocations by non-MediaCodec decoders. These are
caught in SimpleDecoder on the decoder thread and reported as
UnexpectedDecodeException.
3. Input buffer allocations by non-MediaCodc decoders in their
constructors. These are currently caught on a higher-level and
reported as ExoPlaybackException.TYPE_OUT_OF_MEMORY.
For consistency and to prevent catching OOM errors without known cause
we can remove the generic TYPE_OUT_OF_MEMORY and catch the specific
exception where it occurs to report it as an
ExoPlaybackException.TYPE_RENDERER. This also has the added advantage
that the format metadata is added to the exception.

This potentially allows a caller to resize their buffers to take into account
the required size.
It's kept as an IllegalStateException, since most use cases where it's thrown
still reflect invalid states, and since making it a checked exception requires
marking a lot of methods with throws clauses.

Whether a resource resolves to a known length or not is more than just
a property of the resource & data source - for example if
`DataSpec.flags` contains `ALLOW_GZIP` then the length might be
unresolved. More generally, a `DataSource` could randomly return
`C.UNKNOWN_LENGTH` from `open()` 50% of the time and still fulfil the
`DataSource` interface. This makes it ~impossible to write a meaningful
assertion aroun this.
So this change relaxes the assertion slightly to more closely match the
definition of the `DataSource` interface.
We leave the `resolveToUnknownLength` toggle in
`WebServerDispatcher.Resource` because this is still useful for
simulating the case of a server that is serving a file it doesn't
know the length of.

This is a partial revert of
46598a46fd
The change from reset(int) to setPosition/Limit() in this file was
incorrect, the reset(int) call is important because it ensures
`bitmapData` is large enough for the `buffer.readBytes` call on L188.

- Support setting the user-agent in CronetDataSource
- Support setting the default user-agent in CronetEngineWrapper
- Use the underlying network stack's default user-agent by
default. Many applications will configure the underlying
CronetEngine or OkHttpClient with a user-agent that they
expect to be used throughout their app, so always overriding
this with our own default, on reflection, is not the best
thing to do!

BatchBuffer has three different clear methods (clear, flush,
batchWasConsumed), and it's not hugely clear what each of them
does. In general, BatchBuffer owning the sample buffer seems
more complicated than having the caller own it, particularly
when it can be "pending" inside of the batch buffer.
This change moves ownership of the sample buffer to the
caller. BatchBuffer is simplified as a result. There are also
two behaviour changes:
1. The buffer's timeUs field is now set to the first sample's
timestamp, rather than the last sample's.
2. A key-frame in the middle of the batch no longer causes the
batch buffer to be considered a key-frame. Which seems like
the right thing to do, because the batched data cannot be
decoded independently of whatever came before it.

There is a race condition when initializing the downloads database. The
constructor of the DownloadManager kicks-off the database initialization
in its internal thread, but at the same time an app can try to access
the database directly through the manager's download index, e.g. doing
DonwloadManager manager = new ...
manager.getDownloadIndex().getDownload("id");
might enter DefaultDownloadIndex.ensureInitialized() from two threads.
When upgrading the downloads table from version 2 to version 3, the
first thread that enters the database transaction in ensureInitialized()
will drop and recreate the table using the v3 schema. Then, the second
thread will attempt to read from the newly created table using the v2
schema, which will fail.
This race condition was not introduced in 2.12 but was there already.
However, prior to 2.12, the code only dropped and re-created and the
table and did not attempt to read any data. Hence, if the race condition
happened, the code would drop and create the table twice, but no error
would occur.

In many cases we just used "playback speed" as a detailed Javadoc
parameter or return type definition. This doesn't define which scale
the speed is using.
PlaybackParameters as the main point to set the speed already uses a
more precise wording to describe the value as a factor by which playback
will be sped up.
This change replaces other usages of "playback speed" with this wording
whereever we would usually add a unit, keeping "playback speed" for
summary statements etc to reference the general concept that doesn't
usually require a unit.

The experimental setting shows positive results and can be turned
on by default. To avoid adaptation between HLS audio formats without
bitrates, we need to ensure that only formats with bitrates are
considered for adaptation.
Also added tests for these features.

The AsynchronousMediaCodecCallback has logic to retain a pending
output format in case flush() is called. This commit fixes a case where
calling flush() again while an output format is pending would nullify
the pending output format.
A unit test is added in AsynchronousMediaCodecCallback but not the
AsynchronousMediaCodecAdapter. That is because the adapter operates
directly on top of MediaCodec, but Robolectric's ShadowMediaCodec
produces an output format on every MediaCodec.start(). This is
unrealistic when operating MediaCodec in asynchronous mode where we
need to call MediaCodec.start() after every MediaCodec.flush().

- The AdaptiveTrackSelection doesn't need to use the experimental
terminolgy because the code is always triggered if there are multiple
adaptive selections.
- It's also confusing to pass the state on the outside after the object
creation, so moving everything into a simple control flow again where
the adaptation checkpoints are passed in via the constructor.
- Instead of triple arrays, we can use more readable named structures.
- The calculation of the checkpoints can be cleaned up to be more
readable by moving things to helper methods.
- The reserved bandwidth from all fixed track selections is really just
a special case of multiple parallel adaptataions. So this logic doesn't
need to be separate.
- The whole logic also didn't have test coverage so far. Added tests
for the actual adaptation using these checkpoints and the builder
calculating the checkpoints.
Overall this should be a no-op change.
