Based on the Common Media Client Data (CMCD) specification key-value pairs should be sequenced in alphabetical order of the key name in order to reduce the fingerprinting surface exposed by the player.

Added more comprehensive Javadoc around setting custom data and verification on key format.
Changed adding custom data as a `String` to `List<String>`. This would enable us to sort all keys to reduce the fingerprinting surface.

Modifies the `ChunkSource.getNextChunk(long, long, List, ChunkHolder)` method in the `ChunkSource` interface to `ChunkSource.getNextChunk(LoadingInfo, long, List, ChunkHolder)`.
LoadingInfo contains additional parameters, including `playbackRate` and `lastRebufferRealtimeMs` in addition to the existing `playbackPositionUs`. The additional parameters will allow us to pass these information to Common Media Client Data (CMCD) logging.

Periods that are not the last in the manifest are always ended
and non-dynamic periods are also always ended by definition.
Also, some periods may not be able to declare their final duration
accurately and we need to account for some inaccuracy. This can be
done by testing whether no further full segment within the duration
can be expected.
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.

This changes all MediaSources in our library to allow updates to
their MediaItems (if supported).

This avoids issues with potential number clashes with ID_UNSET.
Also fixes some further parsing where adaptation set ids are referenced
from manifest properties.
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`.

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.

The call doesn't currently reset the already loaded suppliers and
factories. Also fix the supplier loading code to use a local copy
of the current dataSourceFactory to avoid leaking an updated
instance to a later invocation.

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.

This method has been deprecated since 2.12.0 ([commit](d1bbd3507a)).
Also remove
DashMediaSource.Factory#setLivePresentationDelayMs(long, boolean), this
method has been deprecated since 2.13.0 ([commit](41b58d503a)).

The `main` role distinguishes a track from an `alternate`, but unlike
`SELECTION_FLAG_DEFAULT` it doesn't imply the track should be selected
unless user preferences state otherwise. e.g. in the case of a text
track, the player shouldn't enable subtitle rendering just because a
`main` text track is present in the manifest.
The `main`/`alternate` distinction is still available through
`Format.roleFlags` and the `ROLE_FLAG_MAIN` and `ROLE_FLAG_ALTERNATE`
values.
This behaviour was originally [added in 2.2.0](7f967f3057),
however at the time the `C.RoleFlags` IntDef did not exist. The IntDef
was [added in 2.10.0](a86a9137be).

Some have been deprecated since 2.13.0
([commit](5b9fa7d7d9)):
* `setDrmSessionManager(DrmSessionManager)`
* `setDrmHttpDataSourceFactory(HttpDataSource.Factory)`
* `setDrmUserAgent(String)`
And the rest have been deprecated since 2.12.0
([commit](d1bbd3507a)):
* `setStreamKeys(List<String>)`
* `createMediaSource(Uri)`

For DASH manifests, we merge min/max live latency values from various
sources and they may not be consistent with each other. To ensure we
use a sensible configuration in all cases, we can add more correctness
checks:
1. Limit the min/max values to fall into the available live window.
2. Ensure that maxLatency >= minLatency in all cases.

This allows to give TrackGroups an identifier. The underlying goal is
to provide a way to make otherwise identical TrackGroups
distinguishable.
Also set this id in all internal sources that may produce identical
TrackGroups in certain edge cases.

MediaSource can be reused with other Player instances after they
have been released, so we need to set the PlayerId when preparing
the source. Access can mostly be handled by the implementation in
BaseMediaSource.
