This makes charset-heavy tests easier to read (and I'm going to add some
more in a follow-up change).
Also switch to Truth's `isEmpty()` assertion as prompted by a lint
check.

AudioManager internally assumes the thread is was created on can be
used as a callback thread. Since the AudioManager is only created
once in the lifetime of an app, we need to make sure its obtained
on a thread that stays alive.

On API < 26, the callback thread couldn't be set and the current compat
code assumes it's always the main thread. This isn't true, however,
because AudioManager uses the thread on which it was first instantiated
anywhere in the app.

Before this change constructors of `TimelineWindowDefinition` used
`windowOffsetInFirstPeriodUs` for both, `positionInFirstPeriodUs`
and `startTimeUs` of the exposed `Timeline.Window`.
Adding `windowStartTimeUs` differentiates these two properties which
allows using `FakeTimeline` for unit tests that emulate live streams
with a forward moving live window in the period like `HlsMediaSource`
constructs a `SinglePeriodTimeline` for live.
A `TimelineWindowDefinition.Builder` is added for API usability and
sanitation.

This was introduced in 841bdc6efe.
There's no need to cast the `char` (2 bytes) down to a `byte` in order
to pack it into an `int` (4 bytes) alongside a short (2 bytes).
We also don't need to use `short` to track the character count (max 4
with UTF-8) - a single byte is enough. This change also uses
`Ints.fromBytes` to avoid having to reason about how casting &
bit-shifting interact.
This change introduces a test which reproduces the failure reported in
Issue: androidx/media#2167.

This ensures it's easier to handle these State updates in other
helper classes if needed.

In a image sequence, seek to after the image duration should render the final
image frame. But currently it hangs as ConstantRateTimestampIterator doesn't
output any timestamp in this case

Add an option to GlMatrixTransformation to choose the OpenGL texture
minification filter.
When mipmaps are requested, mipmaps are generated with
`glGenerateMipmap()`.

This avoids that these settings have to be resolved inline,
potentially blocking the main thread. They can be resolved at
the time of track selection on a background thread instead.
As a side effect, we can also remove the context parameter from
the Builder. Having the Context in the Builder is also a bad sign
in the first place because it implies the potentially blocking
calls can happen.

When reading quickly this suggests something 'real' was null (similar to
a `NullPointerException`), but it's actually just the message from the
superclass.
Seen in stack trace in Issue: androidx/media#2074:
```
Caused by: androidx.media3.common.ParserException: null {contentIsMalformed=true, dataType=1}
```

This requires some additional state handling to update the full
state atomically and guess placeholder states while updates are
in progress, using the newly added BackgroundThreadStateHander.
Some tests also needed to be adjusted to account for the fact
that the actual audio system change doesn't happen inline
anymore.

This is a common pattern in media3 libraries where tasks are handled on a
background thread, but the calling thread sees an immediate state update
with a best-guess placeholder. This makes the integration for the caller
very easy as the API surface appears to be synchronous.
This util is a helper class to handle this logic and test it separately.
