Previously `ChannelMixingAudioProcessor` output float because it was
implemented using the audio mixer's float mixing support.
Move the implementation over to just using the `ChannelMixingMatrix` and make
it publicly visible in the common module so it can be used by apps for both
playback and export.
Also resolve a TODO that no longer had a bug attached by implementing support
for putting multiple mixing matrices to handle different input audio channel
counts, and fix some nits in the test code.
Tested via unit tests and manually configuring a `ChannelMixingAudioProcessor`
in the transformer demo app and playing an audio stream that identifies
channels, and verifying that they are remapped as expected.

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

`sed` has a different in-place command line syntax in FreeBsd
than GNU tools. This change makes the `sed` commands work with
FreeBSD `sed` on OSX in bash and zsh shells.

MediaItems are not meant to be unique in a playlist. If a legacy
session publishes multiple items that get converted to equal MediaItems,
the current code fails because we look up queue ids in a Map (that
doesn't allow duplicate entries).
Fix this by storing a simple list of items with additional data.

* Add a new event `onAudioCapabilitiesChanged` in `AudioSink.Listener` interface.
* Add an interface `RendererCapabilities.Listener`, which will listen to `onRendererCapabilitiesChanged` events from the renderer.
* Add `getRendererCapabilitiesReceiver` method for `TrackSelector`, and register/unregister the `TrackSelector` as the `RendererCapabilitiesReceiver` (if implemented) when the `ExoPlayer` is initialized/released.
* Trigger the `AudioSink.Listener.onAudioCapabilitiesChanged` and further `RendererCapabilities.Listener.onRendererCapabilitiesChanged` events when the audio capabilities changes are detected in `DefaultAudioSink`.

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.

For multi-period live streams the content timeline for
which the global ad playback state has been split needs
to be kept together to not run into a race between
timeline refreshes and ad events.

While playback thread is 'asleep' during audio offload playback, the playbackInfo.positionUs is not being constantly updated. During this time, the returned value from getCurrentPosition should return an estimate based on the most recent value and playback speed.

The value returned by `player.getContentPosition()` is calculated
in the timeline based on the position of the first period in the
window. In a single period live stream this position is advanced
when the live window advances on timeline refresh.
This calculation has produced slightly varying values below 1000
us which are likely caused by us/ms truncations for public API
values that we use in the IMASSAIMediaSource.
However, `AdGroup.timeUs` is the (recorded) content position at the
moment when the first ad of the an ad group has been inserted. While
playing an ad, we can always use this value instead of
`getContentPosition()` to not require recalculation.

Playback parameter signalling can be quite complex because
(a) the renderer clock often has a delay before it realizes
that it doesn't support a previously set speed and
(b) the speed set on media clock sometimes intentionally
differs from the one surfaced to the user, e.g. during
live speed adjustment or when overriding ad playback
speed to 1.0f.
This change fixes two problems related to this signalling:
1. When resetting the media clock speed at a period transition,
we don't currently tell the renderers that this happened.
2. When a delayed speed change update from the media clock is
pending and the renderer for this media clock is disabled
before the change can be handled, the pending update becomes
stale but it still applied later and overrides any other valid
speed set in the meantime.
Both edge cases are also covered by extended or new player tests.

MediaCodecRenderer currently has two independent paths to trigger
events at stream changes:
1. Detection of the last output buffer of the old stream to trigger
onProcessedStreamChange and setting the new output stream offset.
2. Detection of the first input buffer of the new stream to trigger
onOutputFormatChanged.
Both events are identical for most media. However, there are two
problematic cases:
A. (1) happens after (2). This may happen if the declared media
duration is shorter than the actual last sample timestamp.
B. (2) is too late and there are output samples between (1) and (2).
This can happen if the new media outputs samples with a timestamp
less than the first input timestamp.
This can be made more robust by:
- Keeping a separate formatQueue for each stream to avoid case A.
- Force outputting the first format after a stream change to
avoid case B.

This change fixes an issue that can be reproduced when
a controller `onConnect` creates a `QueueTimeline` out
of the state of a legacy session and then `prepare` is called.
`activeQueueItemId`, `metadata` and the `queue` of the legacy
session are used when a `QueueTimeline` is created. The change
adds unit tests to cover the different combinatoric cases these
properties being set or unset.
