Main improvement is to switch away from ExoPlayerTestRunner and to
split out the waiting component so that the same class can be used
from Robolectric tests in the future.
The only functional difference is that that BufferLengthLogAction
is removed completely because the data isn't used downstream and the
method of collecting this data is a bit arbitrary.

This can happen for instrumented tests that are run on a non-Looper
thread. If these tests send a message to a Looper thread to start the
test procedure, they should just triger the message directly as before.

- The order of sample stream (and thus the order in which loads are
triggered) currently depends on a Set and thus on the hash codes
of the objects that change with every run. Changing to a List solves
this problem.
- The FakeAdaptiveDataSet directly created a static Random (with random
seed) to compute the variation of chunk sizes. Changing this to an
injected Random object that can always be initialized with the same
seed also removed this randomness from the tests.

This is achieved by only triggering one message at a time. After
triggering a message we send another to ourselves to know when the
following message can be triggered.
Other required changes:
- The messages need to be sorted correctly (by time and creation order)
- To prevent deadlocks when one thread is waiting for another,
we need to add new method to Clock to indicate that the current
thread is about to wait. This then allows us to trigger messages
from other threads in FakeClock.
- AnalyticsCollectorTest needed some adjustments:
- onTimelineChanged now deterministically arrives after the initial
timline is already known, so some of the period information changes
from window only to full period info.
- The playlistOperations test suffers from a bug that the first frame
is rendered too early and that's why we now get additional events.
PiperOrigin-RevId: 353877832
We currently only remove messages that have already been sent
to the actual Handler, not the pending ones that are only kept
in the FakeClock. Fix this by also removing matching messages
from the FakeClock list.
PiperOrigin-RevId: 353877049
Currently only delayed messages are handled. Change this to handling
all messages so that we have more control over their execution order.
This requires adding a new wrapper type for the Message to support
the obtainMessage + sendToTarget use case.

`TrackSelection` had mutation methods which were to be called only
internally by ExoPlayer components but were exposed in the
public `Player` interface.
The mutation methods have been moved out of `TrackSelection`
to a new class `ExoTrackSelection`.
Current track related read-only method have also been moved out,
because they are actually something quite unclear.
Even for a single item playlist, it's the track being buffered rather
than the track being played, which is unclear.
But when you have a playlist it starts to get really confusing,
because if the next item is being buffered, then it's actually
the last track to be buffered in the currently playing item.
As a final aside, the implementations don't do proper thread synchronization
to ensure visibility of updated state by the calling thread.
Exposing those mutable methods in the public `Player` interface
was problematic because they leaking internal concepts of `ExoPlayer`.
This is also required to minimize the `Player` interface for long term
stability.
`ExoTrackSelection` is a subclass of `TrackSelection`.
This is not ideal as an `TrackSelection` implementation could
break the current immutability.
This was done in order for this refactor to be simpler.
A future patch will fully split the two classes.
All `MediaPeriod` and `Sources` had to be updated to use the new
`TrackSelection` dynamic aspect class name.
An alternative would have been to break ExoPlayer's public API, keeping
`TrackSelection` as the dynamic aspect name, and calling the public static
aspect class `TrackSelectionState` or similar.
Nevertheless, while it would have impacted less files, it would have
many more small apps and casual users of ExoPlayer.

This ensures the message devilery is governed by the clock.
Also replace setting a Handler with a Looper to facilititate this
change.

Add a test to DataSourceContractTest that asserts the gzip flag is
either ignored or handled correctly.
Add a test resource to DefaultHttpDataSourceContracTest that enables
gzip compression on the 'server' and checks it's handled correctly by
the client.

- 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.

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.
PiperOrigin-RevId: 351124246
The length needs to change depending on the positition/length parameters
passed to DataSpec, so it doesn't really make sense to keep this private
method - it's clearer to in-line the calls in each test.

This replaces all the duplicated logic previously implemented in
FakeSampleStream and more closely follows the pattern of how
SampleStreams are used from real MediaPeriods.
Some tests needed adjustments because using real the SampleQueue
improved behaviour:
- Waiting for isLoading is only needed once even across period
boundaries because the real SampleQueue doesn't have the on/off
pattern.
- AnalyticsCollectorTest.playlistOperations() was wrongly asserting
that some pre-buffering events. The new version is more intuitively
correct we pre-buffer the second item during the initial loading
phase (thus period1seq1) and keep the buffer in the queue after
the removal operation.

I decided not to migrate all the tests in one CL to keep the diff
manageable. I'll make follow-up CLs to migrate the tests, and eventually
delete TeeCodec and all associated logic.
I couldn't completely remove the dump diff because
ShadowMediaCodec.getCodecInfo() (which would give me access to the MIME
type) doesn't seem to work properly - it returned video/avc when
name=exotest.audio.aac, and looking into the code it looks like there's
some native methods that are missing shadow implementations.

The adaptive period currently extends the base (non-adaptive) period
to share common MediaPeriod boilerplate code.
However, once we start using the real SampleQueue in FakeMediaPeriod
the common code becomes even less and the overhead to support
multiple stream implementation from the base class is no longer
worth it. Thus, this change removes the class hierarchy and copies
the common parts to FakeAdaptiveMediaPeriod.

Before this we added the resource info to Truth assertions, but the
same info is missing if an exception bubbles out of the SUT.

Changes MetadataRetriever and Transformer so that their
respective tests don't need to manually control the SystemClock

The workaround to post a message was needed to ensure we
receive any final onIsPlayingChanged event before the test
is finished (to record the correct playing time).
Using onEvents allows us to do this synchronously as the
callback guarantees that there is no other pending event.

In many cases it doesn't matter for the test itself how many windows
a timeline has, or even how the timeline of a MediaSource looks like.
And since we introduced the MediaItem-based APIs, single-window
Timelines are the only fully supported Timelines. Thus there is no
point in specifiying this explicitly.
Using these assumptions, we can remove some boilerplate when setting
up standard FakeTimelines or FakeMediaSources with a standard
FakeTimeline.

This only has a couple of simple tests for now. We'll add more tests
after we've written some concrete sub-class tests for various
DataSource implementations.
I've included a concrete FileDataSourceContractTest as a demonstration.

This information is already available in the MappingTrackSelector,
but not currently forwarded to the TrackSelection.Factory.
This makes it more complicated (or impossible) to depend on period
or manifest information in the track selection (for example to only
select tracks which are cached for the current format).
