In order to support building with `gradle` a new `build.gradle` file was added together with `Android.mk`, `Application.mk`, and `libiamf.mk` necessary for local builds with NDK.
After this change, IAMF files may also be played in the ExoPlayer demo built locally (without blaze).

This is only used as part of legacy subtitle decoding. If any apps are
using it directly (rather than via `DashMediaSource` or `SsMediaSource`)
they probably need to enable legacy decoding in `TextRenderer` to avoid
playback failures.

The method currently has two ways of operating with a complicated
contract:
1. outputBuffer == null -> sets a new outputBuffer and starts
draining it as far as possible.
2. outputBuffer != null -> continues draining a previous buffer,
requires that the input parameter is the same as outputBuffer.
This contract can be made cleaner by splitting the logic into
(1) setting a new output buffer and (2) draining the output buffer.
Only one parameter is needed for each method and there is no
requirement to pass in the same argument as before because we already
know what we are draining. This also means the caller of the method
doesn't have to keep track of the actual outputBuffer, allowing
further processing steps in the future that change the drained
instance.

This makes it clearer that the part inside and outside the parentheses
are clearly different, and not "just" a reference to `Player.Events`.
Specifically this syntax is showing that the function has a `Player`
"receiver", **and** is a function from `Player.Events` to `Unit`.

This makes the class available to custom MP4-parsing implementations,
while also allowing it to be used by `muxer` in future.
'Box' is the term used throughout the ISO 14496-12 spec, while the
'Atom' nomenclature was used in an earlier form of the spec
(Quicktime).
This change moves it from `extractor.mp4.Atom` to `container.Mp4Box`,
to be consistent with existing MP4-specific types in the `container`
module like `Mp4TimestampData`.

Use ExoPlayer dynamic scheduling to reduce the render() interval for
older API devices where `DefaultCodec.getMaxPendingFrameCount()` is set
to 1 in order to prevent frame drops.
Controlled via API on DefaultDecoderFactory.
Add TransformerForegroundSpeedTest that mimics transcoding while the app
is in foreground.

The parameter class will allow addition of more
parameters (link shouldInterleaveSamples), which are specific to
editable video file format.

AMR samples with identical data but different names, previously used to generate uniquely named dump files, have been deleted. Instead, `AssertionConfig` is now used to set the dump file prefix, ensuring files are generated with unique names.

Previous to this change, `FrameworkMediaDrm.requiresSecureDecoder`
ignores its `sessionId` parameter on API 31+, and uses only the
`mimeType` parameter. This means the result [assumes the session is
opened at the 'default security
level'](https://developer.android.com/reference/android/media/MediaDrm#requiresSecureDecoder(java.lang.String)):
> The default security level is defined as the highest security level
> supported on the device.
This change is a no-op in all (?) cases, because the `ExoMediaDrm`
interface only exposes the zero-arg `openSession()` method, which in the
framework case **also** assumes the highest security level is preferred:
> By default, sessions are opened at the native security level of the
> device.
However, it seems more obviously correct to only make this
"highest/native security level" assumption in one place
(`openSession()`), and check the session's **actual** security level
everywhere else.

Constant bit rate (CBR) seeking can be enabled even when the length of the file is not known.
Additionally, dump files for these files have been updated to accurately log the `position` when `timeUs` is set to `0`.

This method was added in API 31 (S) but it's non-functional
(incorrectly, silently, returns `false`) on the Widevine plugin version
(`16.0`) from R (API 30), which some devices up to at least API 34 are
still using.
This results in ExoPlayer incorrectly selecting an insecure decoder for
L1 secure content, and subsequently calling
`MediaCodec.queueInputBuffer` instead of `queueSecureInputBuffer`,
which is not supported and generates the following error:
> Operation not supported in this configuration: ERROR_DRM_CANNOT_HANDLE

The TrackToken is primarily for public API.

When there is an exception thrown from the `LoadTask`, the `Loader` will call `Loader.Callback.onLoadError`. Some implementations of `onLoadError` method may call `MediaPeriod.onContinueLoadingRequested`, and in the `PreloadMediaSource`, its `PreloadMediaPeriodCallback` will be triggered and then it can further call `continueLoading` if it finds needed. However the above process is currently done synchronously, which will cause problem. By calling `continueLoading`, the `Loader` is set with a `currentTask`, and when that long sync logic in `Loader.Callback.onLoadError` ends, the `Loader` will immediately retry, and then a non-null `currentTask` will cause the `IllegalStateException`.

Moving this field to `IamfDecoder` instead of `iamf_jni` allows multiple instances of the IAMF decoder with possibly different configurations at the same time.

Check if the output device supports spatialization for the requested output format. If so, return a stream decoded for 6 channels in a 5.1 layout. Otherwise, return a stream decoded for 2 channels in a binaural layout.

This is groundwork to moving `Atom` to the `container` library, which
we want to do before making it public (so it can be used by `muxer` in
future).

After this change, a WakeLock of PowerManager#PARTIAL_WAKE_LOCK level would be acquired when the media is paused due to playback attempt without suitable output.
This WakeLock will be release either when the suitable media output has been connected or the set timeout to do so has expired.
