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.

- To support looping EditedMediaItemSequences, we need a way to tell the
AssetLoader that a sample couldn't be consumed and that it should retry
later. This is necessary in case we don't know yet whether the looping
sequence should load more samples because the other sequences haven't
made sufficient progress yet.
- The decision on whether to consume a sample is based on its timestamp
so it needs to be available.

Instead of using a long frameDurationUs with Math.floor, use a double
frameDurationUs with Math.round,
Before, playing an image with 30 fps over 1 second would result in the final
timestamp not being aligned to the expected 1 second timestamp. Over long
periods of time, this can lead to significant timestamp drift. Additionally,
for TimestampWrapper and constrained multi-asset, where TimestampWrapper
begins the 2nd effect on the 2nd asset's startTimeUs, this floor() behavior
can lead to the first few frames of the 2nd asset using the first asset's
effects, due to timestamps being mismatched.

This test is not run on emulator, triage or postsubmit, and does not
provide value to the library in it's current state. It could be
deleted, however it still may have use for analysis of exported files
on MH.

* Add AudioDeviceCallbackApi23 class which extends the AudioDeviceCallback.
* Add registerAudioDeviceCallback and unregisterAudioDeviceCallback methods for Api23.
* Modify the logics of AudioCapabilitiesReceiver constructor, register and unregister methods.

This change makes sure that the `AdPlaybackState` of any period can
contain an empty postroll placeholder.
The placeholder postroll should be represented in the `MediaPeriodId`
of a content period as `nextAdGroupIndex`, but should be ignored when
building the list of `MediaPeriodInfo` in the `MediaPeriodQueue`. This
is required to allow to add an ad group to ad playback state of the
content period that is currently being played, instantly insert an ad
period into the media period queue and immediately transition playback
to the new period.
This change makes sure and tests that
- a live server side inserted postroll placeholder can be inserted to
a `AdPlaybackState` in well-defined and tested way (helper method)
- a postroll placeholder is NOT ignored when
`AdPlaybackState.getAdGroupIndexAfterPositionUs` is called (this
is required when evaluating the `nextAdGroupIndex`).
- a postroll placeholder is ignored when
`AdPlaybackState.getAdGroupIndexForPositionUs` is called (this is
required to not attempt to play the ad and is analogous to ignore the
post roll placeholder in a single period timeline).
- `MediaPeriod.getFollowingMediaPeriodInfo()` does not include a
`MediaPeriodInfo` for the placeholder postroll when building the
queue.

Split test/ TransformerEndToEndTest into SingleMediaItemEndToEndTest and
SingleSequenceEndToEndTest to reduce the file size and split the tests
by category.

By making this method accept context, we can use DefaultDataSource.Factory in the DatasourceBitmapLoader to support a wider range on URI schemes in Bitmap Overlays. (and implement a local file picker for images for custom bitmap overlays in the demo transformer app)

Callbacks onTrackCount and onTrackAdded can be called simultaneously
from different threads.
Before this fix, it was possible for the MuxerWrapper and
FallbackListener track count to never be set, or to be set
with incorrect values.

We currently rely on the raw playback head position to check if any
data is pending in the AudioTrack (e.g. to know if the renderer is
still ready). We can use the value returned from getCurrentPositionUs
instead to align the "isReady" logic with the playback position logic.
This has the side effect that getPlaybackHeadPosition position is called
less often when the position is obtained via getTimestamp.

Segment timelines are technically allowed to be empty, but not all places

To create this file TextureInfo has been moved to common and renamed to GLTextureInfo.
We'll look to expand the interface in future to cover more of the methods around GL object maintenance in future as required.

- This is to make sure we know about all the tracks before initializing
the SamplePipelines. This allows to set the muxer and the fallback
listener track count before the SamplePipelines are built.
- As a result, the test files had to be updated because the order in
which the tracks are written has changed.
- The ImageAssetLoader also had to be updated to call onOutputFormat
repeatedly until it returns a non-null SampleConsumer.
- Also fix the trackCount sent to the muxer and fallback listener. The
correct track count can be computed now that we know about all the
tracks before building the SamplePipelines.

Before, we used to never call glDeleteFramebuffers, which could
in theory lead to leaks in the number of frame buffers
available and make releasing the GL context more expensive.

The `@CallSuper` annotation should help catch cases where subclasses are
calling `delegate.addListener` instead of `super.addListener` but it
will also (unintentionally) prevent subclasses from either completely
no-opping the listener registration, or implementing it themselves in a
very custom way. I think that's probably OK, since these cases are
probably unusual, and they should be able to suppress the warning/error.

All audio tracks should either all be transcoded or all be transmuxed.
Same for video tracks.
To achieve this, simplify the behaviour of transmuxAudio/Video.
