Refactored `CmcdLog` to `CmcdHeadersFactory` for improved representation of its purpose and updated implementations.

PiperOrigin-RevId: 552831995
Updated `ExoTrackSelection` to provide the most recent bitrate estimate, enabling the inclusion of measured throughput (mtp) as a CMCD-Request field in Common Media Client Data (CMCD) logging.
Additionally, made changes to the `checkArgument` methods in `CmcdLog` to prevent the use of default values in certain cases.

When selecting progressive and HLS tracks, we currently check if
we can either seek in the existing samples or are starting from the
beginning of the stream. In both cases, we don't need to reload the
stream and can continue reading.
Seeking to the beginning isn't side-effect free though because it
also sets the startTimeUs to zero. Whether a seek to the beginning
is successful also depends on whether we already loaded a sample or
not. This mean that the startTimeUs value is set (or not set) based
on the speed of the Loader thread even for the same input starting
from the beginning. This race condition means the actual samples
we write to the stream may differ if the stream has initial samples
with negative timestamps.
We can avoid this race condition by checking if the queue is empty
first, so that we only call seekTo if really needed.

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

This change uses this new method everywhere we currently `instanceof`
check an `Extractor` directly. This allows us to introduce
wrapping/delegating `Extractor` instances - because the `instanceof`
checks will continue to operate on the underlying instance.
HLS is a slightly different case, because it directly re-instantiates
`Extractor` instances, which is not compatible with an arbitrary
wrapping structure. Luckily the only `Extractor` instances that HLS
re-instantiates do not support muxed subtitles, so won't be wrapped
in the first place (although future changes might use the
delegating-`Extractor` pattern for other purposes, which might affect
HLS).

Instead of providing `playbackDurationUs` and `loadPositionUs` individually, which are used to calculate the buffer duration for CMCD logging, we can directly pass the pre-calculated `bufferedDurationUs` available in the `getNextChunk` method of the chunk source classes.

The existing NullableType has been deprecated 5 years ago and causes
crashes in Kotlin apps because Kotlin doesn't recognize this annotation
as a nullable type annotation.
While we can't align on a single @Nullable annotation yet, we can at
least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all
requirements, including full Kotlin compatiblity. To avoid the
cumbersome name, we can redefine it as our own @NullableType
annotation. (We can't use @Nullable to avoid name clashes with the main
@Nullable annotation from AndroidX)

Add `HlsMediaSource.Factory.setTimestampAdjusterInitializationTimeoutMs(long)` to set the timeout for the loading thread to wait for the `TimestampAdjuster` to initialize. If the initialization doesn't complete before the timeout, a `PlaybackException` is thrown to avoid the playback endless stalling. The timeout is set to zero by default.
This can avoid HLS playback endlessly stalls when manifest has missing discontinuities. According to the HLS spec, all variants and renditions have discontinuities at the same points in time. If not, the one with discontinuities will have a new `TimestampAdjuster` not shared by the others. When the loading thread of that variant is waiting for the other threads to initialize the timestamp and hits the timeout, the playback will stall.

Add support for including Common Media Client Data (CMCD) in the outgoing requests of adaptive streaming formats DASH, HLS, and SmoothStreaming.
API structure and API methods:
* CMCD logging is disabled by default, use `MediaSource.Factory.setCmcdConfigurationFactory(CmcdConfiguration.Factory cmcdConfigurationFactory)` to enable it.
* All keys are enabled by default, override `CmcdConfiguration.RequestConfig.isKeyAllowed(String key)` to filter out which keys are logged.
* Override `CmcdConfiguration.RequestConfig.getCustomData()` to enable custom key logging.
NOTE: Only the following fields have been implemented: `br`, `bl`, `cid`, `rtp`, and `sid`.

`prepare()` now logs a warning if it's called before `setPlayer()`
because it's not possible to tell if it's being called on the wrong
thread (since 3480a27994).

other and flips the order to be more correct.

It is not possible to provide a safe deprecation path because
BaseTrackSelection can't easily know which of the methods is
implemented by subclasses.

The `DashMediaSource` wrongly added an offset to the media times set
to the `MediaLoadData`. With this the `startTimeMS` and `endTimeMs`
don't represent the positions in the period but in the stream.
`DashMediaSource` was the only call site that was setting the offset
to a non-zero value. So if we are using 0 for the `DashMediaSource`
as well, the offset is redundant and we can remove it everywhere.

This makes two fixes:
1. Remove `HlsSampleStreamWrapper.Callback` (package-private) from the
list of interfaces implemented by `HlsMediaPeriod` (`public`) and
move the implementation to a private inner class instead. This avoids
Metalava complaining about a public class that inherits from a
package-private type.
2. Reduce the visibility of
`RtpPayloadFormat.isFormatSupported(MediaDescription)` from `public`
to package-private. The `MediaDescription` type is already
package-private, so this method was already unusable outside the
package.

This makes two types of fix:
1. Align parameter names on overridden methods where the superclass
has `@param` javadoc.
2. Use `@hide` on `protected final` methods that refer to package-private
types. This will hide these symbols from Dackka javadoc generation
but not (currently) from the artefacts distributed on Maven. These
methods are currently unusable outside their package anyway (e.g. by
external developers) because of the dependency on a package-private
type.
This also changes some HLS, SmoothStreaming, and IMA code where I've renamed
parameters of overridden methods to be consistent across the type
hierarchy.

The call doesn't currently reset the already loaded suppliers and

This is a breaking change if the annotation itself is in use in Kotlin
code. It's judged that the IntDefs in this commit are unlikely to be
referred to often in Kotlin code. This is because they're either:
- Related to esoteric parts of the library, or
- In a common part of the library but only returned from methods (and
never passed to callback methods).
A follow-up change will fix the positions of existing usages to match
this new config.

This is not backwards compatible if the @SelectionReason annotation is
used in Kotlin code, but before this change there aren't many library
surfaces that return a value annotated with @SelectionReason, so it
seems relatively unlikely that it is in use in any/many apps.
A follow-up change will fix the positions of existing usages to match
this new config.

either private or package-private.

PiperOrigin-RevId: 426372273
The longer list of targets is only necessary for backwards
compatibility with existing Kotlin code that will stop compiling
if the position of the annotation becomes 'wrong' by marking it only
TYPE_USE. Since none of these IntDefs have been released (except in
media3 alpha1) we don't need to maintain this compatibility.
Also add a comment to all the places that *do* need the longer list of
targets, in order to explain why it's there and discourage copy-pasting
when defining new IntDefs in future.
Also fix some single-element arrays to remove the array notation.

Live speed adjustment is used for all live playback at the moment,
but has no user visible effect if the media is not played with low
latency. To avoid unnecessary adjustment during playback without
benefit, this change restricts the live speed adjustment to cases
where either the user requested a speed value in the MediaItem or the
media specifically defined a low-latency stream.
