ExoPlayer is now the trusted source of playlist and can be
used by other components without breaking
SessionPlayerConnector's cached playlist.

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.

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.

Find sbgp and sgpd boxes with grouping_type == seig in the case they don't
come first. Previoulsy we would only find them if they came first.

The sniffer sniffs boxes at the start of the file to try and determine
whether the file is fragmented. However, if the file is extremely short
then it's possible that sniffing will try and read beyond the end of
the file, resulting i EOFException being thrown.
In general it's OK for sniffing to throw EOFException if the file is
not of the correct type. The problem in this case is that EOFException
can be thrown for an actual MP4 file, due to the sniffer continuing up
sniff atoms up to bytesToSearch in case the file is fragmented.

Having both in the trun box is not allowed (see section section 8.8.8.1
of ISO/IEC 14496-12:2015) but this CL makes the code more robust in case
this happens. Before this change, the first sample flag was not read,
making subsequent reads incorrect.

Float values are allowed to be > 0dbfs,
it is just not nominal as it will might
distort the signal when played without
attenuation.
This is also consistent with
[AudioTrack.write(FloatBuffer)](https://developer.android.com/reference/android/media/AudioTrack#write(float[],%20int,%20int,%20int)) that explicitly
allows it up to 3dbfs.

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
