Playlist can now be obtained directly from Timeline windows
in any state. So make ExoPlayer as the trusted source of
playlist, instead of SessionPlayerConnector.

PlayerWrapper still need to keep the list of media items.
It's used to detect whether the Timeline change is caused by
changes in media items or not, and only notify
SessionPlayer.PlayerCallback#onPlaylistChanged() only when
the playlist is really changed.

In order to acquire a placeholder session, clients can call acquireSession
with a format with a null drmInitData.

MediaSession requires prepared Looper in 1.0.3-stable release,
which is the latest stable release for now.

The requirement would be removed in 1.1.0-stable, but workaround
is needed meanwhile.

This change should only affect HLS, where we don't remove the
PAT reader after reading a PAT.

Also re-word some existing subtitle notes

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.

- Applications should generally use DefaultMediaSourceFactory,
  or their own custom implementation if they need one. Having the
  media2 extension implement its own version directly doesn't seem
  that useful.
- Remove support for CallbackMediaItem. This type of MediaItem
  doesn't go cross-process, and it seems like there would never
  be a use case where an app would need to generate one locally.
  If an app needs to provide data from a custom source, it should
  hook into ExoPlayer's way of doing this (i.e., use a UriMediaItem
  with a custom scheme, and inject a custom DataSource that can
  handle this scheme).

- Use ExoPlayer DataSource instrumentation to intercept reads
- Use ExoPlayer Resource URIs
- Use ExoPlayer DefaultMediaSourceFactory

PlayerWrapper throws Exception if getters is called in the
STATE_IDLE. In that case, log may print 50+ lines of stack
traces. It's verbose and can be considered as serious issue.

This CL include folloing changes
  - Change to use ExoPlayer's log class
  - Adjust log level, because it would be consumed by caller
  - Leave log when the debug flag is turned on.

Another CL will remove exceptions between PlayerWrapper and
and SessionPlayerConnector, not to use Exception for ordinary
control flow as the Effective Java suggests.

Even after this change, it's unclear to me why we need so many
assets for these tests. Just doing a minimal pass for now though!

There were two bugs in StyledPlayerControlView:
- Center icons are shown when toggling control view in minimal mode.
- `StyledControlView#setShow{*}Button` methods and corresponding
  `set_show_*_button` attributes didn't work properly.

This CL fixes bugs by controlling the buttons' visibility in one place,
StyledPlayerControlViewLayoutManager.

Being specific, this includes following changes
  - Remove PlaylistManager and TimelinePlaylistManager
    and use Player's playlist API directly.
  - Replace ConcatenatingMediaSource uses with
    ExoPlayer MediaItem.
  - Replace PlaybackPreparer uses with Player#prepare()
  - Add MediaItemConverter for developers to customize
    converting AndroidX MediaItems to ExoPlayer MediaItems
    and vice-versa.
  - Add DefaultMediaItemConverter for providing default
    implementation of both MediaItemConverter
    and MediaSourceFactory.

Note that removing PlaylistManager loses the ability
to suppress individual playlist API. But decided to remove
for simpler API set. The feature can be added back later
via explicit request.

Previously, it refelects isPlaying() and it makes the button to seem
unresponsive when playback error occurs.

AudioTrack.setPlaybackParams can be used to adjust playback speed.
This is preferable to application-level speed adjustment (currently
implemented in ExoPlayer) from API 23 because the speed change
occurs in the mixer, which means that the audio track buffer doesn't
need to drain out before the speed adjustment takes effect.
