Our package-info.java files are annotated with @NonNullApi which results
in everything being non-null by default, so this annotation is never
needed.

Test file produced with:
$ MP4Box -add "sample.mp4#video:colr=nclc,1,1,1" -new sample_18byte_nclx_colr.mp4
And then manually changing the `nclc` bytes to `nclx`.
This produces an 18-byte `colr` box with type `nclx`. The bitstream of
this file does not contain HDR content, so the file itself is invalid
for playback with a real decoder, but adding the box is enough to test
the extractor change in this commit.
(aside: MP4Box will let you pass `nclx`, but it requires 4 parameters, i.e. it
requires the full_range_flag to be set, resulting in a valid 19-byte colr box)

The static and dynamic metadata now build up in a list, such that when
the MediaMetadata is built, they are applied in an event order. This
means that newer/fresher values will overwrite older ones. The MediaItem
values are then applied at the end, as they take priority over any other.

This introduces a new option `setAudioMimeType` in `TranscodingTransformer.Builder` and a corresponding check whether the selected type is supported. This check is done using `supportsSampleMimeType` which is now part of the `Muxer.Factory` and `MuxerWrapper` rather than `Muxer`.
A new field `audioMimeType` is added to `Transformation` and the `TransformerAudioRenderer` uses this instead of the input MIME type if requested.

Decoded video frames can be large and there is no need to retrieve the
corresponding ByteBuffer as we render the decoded frames on a surface
for better performance.

The current API exposes an `ImmutableMap` of
`TrackGroup` -> `TrackSelectionOverride`.
This has several disadvantages:
- A difficult to use API for mutation
(`ImmutableMap.Builder` doesn't support key removal).
- There is no track selection specific methods,
how the generic map API mapps to the selection override is not complex
but to obvious for a casual reader.
- The internal data type is exposed, making internal refactor difficult.
This was done to have the API ready as quick as possible.
When transitioning the clients to the map API in <unknown commit>,
it became clear that the map API was too verbose and not mapping
to the clients needs, so utility methods
were added to make operations clearer and more concise.
Nevertheless, having to use utility method to use easily and correctly
an API is not the sign of a good API.
This cl refactors the track selection API for several improvements:
- Add a type `TrackSelectionParameters` that encapsulate the internal
data structure (map currently).
- For iteration, expose as a list.
- Add a `Builder` for easy mutable operations.
- Add track selection specific methods to avoid having utilities functions.
- Those operations are the same as `DefaultTrackSelector.Parameters`
for easier migration. (`setOverride` was renamed to `addOverride`)
- Move `TrackSelection` classes outside of `TrackSelectionParameters`
as their own top level classes.
The migration of the client code is straightforward as most of it
were already using the previously mentioned utility functions
that are now native methods.
The full migration has not been done yet, and is pending on this cl approval.

* Revert this CL and not get a CL that cleans up these paths in the future by
replying "BLOCKLIST: <provide reason>". This is not reversible! We recommend to
opt out the respective paths in your CL Robot configuration instead:

The HLS Parser converts from a string decimal duration in seconds into long
microseconds.
Because the conversion passes through a java double type it can result in
representation errors.
For example:
`#EXTINF:4.004` -> `Segment.durationUs` of 4003999
This matters because the first sample (which is the IDR) for a segment will be discarded following a seek because of the logic in the `SampleQueue`:
````java
buffer.timeUs = timesUs[relativeReadIndex];
if (buffer.timeUs < startTimeUs) {
buffer.addFlag(C.BUFFER_FLAG_DECODE_ONLY);
}
````
DrmConfiguration.Builder#setLicenseRequestHeaders now rejects null,
since 8fd1381a84
This private method isn't needed at all, it's extracting the headers
from the item that the DrmConfiguration.Builder is already based on.
