ExoPlayer's traditional HLS preparation works by loading a chunk from each track
group, and then tries to use the sample information plus the master playlist
information to generate the preparation's resulting TrackGroups.
There are 3 possible scenarios:
- Supported case: Each variant has a single codec string per track type. We can
assign each track the codec string which matches the loaded sample's type.
- Supported case: Each variant has more than one codec string, but each track
group has a single track. This is the case when different languages use
different codecs. In this case, we can assign whichever codec matches the
loaded sample's mime type.
- Unsupported case: Each variant has more than one codec string, and track
groups contain more than one track. We are not able to safely map tracks to
codec strings because that would require loading a chunk from each track
(which would considerably delay preparation).

This ensures the buffer is not full when the `DefaultLoadControl` determines
whether we should continue loading and thus prevents a false warning about
not having enough memory left.

This change will be followed up by:
- Changes adding APIs to enable the use of MediaParser in each of the supported
media sources.
- Changes removing TODOs related to the change of the stable SDK to API 30.

This change fixes format creation for traditional preparation of streams
where the master playlist contains more than one codec string per track
type.

When disabling a TsExtractor track type because of a missing codec
in the master playlist, look through the entire codecs string
instead of checking the first codec with matching type.

The 'implementation' dependency causes problems when resolving
ListenableFuture in contexts that also include the
com.google.guava:listenablefuture:1.0 dependency.

- Use a setter, which is consistent with how other optional
components are passed.
- Remove nesting where a provider provides another provider.
Since AdSupportProvider then only provides one thing, it
can be renamed to AdsLoaderProvider, which more clearly
expresses what it provides.

This allows us to more easily create different dumps derived from the
same assets.
This moves media/source files from `assets/` to `assets/media/` and
dump files from `assets/` to `assets/extractordumps/` and
`assets/audiosinkdumps/` as appropriate. I intend to add
`assets/playbackdumps/` in a future CL.

- Attach types for placeholder sessions. If a placeholder session will be
attached and a downstream renderer doesn't know what to do with it, then
this attachment is necessary to correctly determine that the renderer
does not support the track.
- Attach types to sample formats. Without this, if playback fails due to
a CryptoException, the ExoPlaybackException that gets thrown spuriously
indicates that the format's DRM type was not supported.

We are not able to associate a codecs attribute to an EXT-X-MEDIA tag if
there is no variant with a matching AUDIO GROUP-ID. Lack of codecs string
prevents chunkless preparation from determining the track type.

After discarding upstream we shouldn't reuse the extractor from the
(newly) last media chunk because the extractor may have been reused
already by the discarded chunks.
Also add an assertion to SampleQueue that prevents the hard-to-detect
failure mode of overlapping sample byte ranges.

Issue: #7244 added this feature to HLS. This change is the exact copy
in ChunkSampleStream to add the same support to the other adaptive
formats.
Note that ChunkSampleStream doesn't support slicing, so we can't cancel
a read-from chunk, and we need to prevent reading into an already
canceled chunk load so that the chunk can be automatically discarded
after the cancelation.

This allows us to enforce the limit because the array can only be
reassigned through reset(byte[]) or reset(byte[], int) (which update
the limit)

These callbacks were only necessary to track the queue in AnalyticsCollector and there is no other known benefit of having them.

getExoMediaCryptoType will only return null for drmInitData == null and
track types for which placeholder sessions are not used. This change
will allow renderers to abstract themselves from format.drmInitData.

Replace `type` with (optional) `mimeType` and add `keySetId` in
DownloadRequest. The DownloadHelper infers the downloading method (DASH,
HLS, SmoothStreaming or Progressive) from the content's MIME type and
URI.
