If there is only one track, we can assume that both boxes refer to the same track
even if the track indices don't match.

MediaDrm.provideXResponse methods only accept the response
corresponding to the most recent MediaDrm.getXRequest call.
Previously, our code allowed the following incorrect call
sequence:

a = getKeyRequest
b = getKeyRequest
provideKeyResponse(responseFor(a));

This would occur in the edge case of a second key request
being triggered whilst the first was still in flight. The
provideKeyResponse call would then fail.

This change fixes the problem by treating responseFor(a)
as stale. Note that a slightly better fix would be to
defer calling getKeyRequest the second time until after
processing the response corresponding to the first one,
however this is significantly harder to implement, and is
probably not worth it for what should be an edge case.

Both boxes should contain the same list of track indices. However, if only one
track index in each list does not match, we can just assume that these belong
together.

Codec initialization may fail in creation, configuration or when start()ing the
codec. If codec initialization fails, there may be other codecs available that
could handle the same format, but currently ExoPlayer can only try to use the
first listed codec for the input format and gives up if it fails to initialize.

This change implements support for optionally falling back to alternative
decoders if initialization fails. MediaCodecSelector can now return a list of
decoders to try in priority order, and use the Format when choosing a codec.
With the default implementation, the codecs and order come from MediaCodecList,
and matches the order used internally by MediaCodec.createDecoderByType (which
implements the same kind of fallback though only to the creation step, without
configuring/starting the codec).

This feature is useful for apps that want to play several videos concurrently on
devices that have software decoders (like OMX.google.h264.decoder), as the new
behavior allows new codecs to be created when no hardware-accelerated decoders
are available.

The list of available codecs is queried when initializing the codec after a
format change that requires a new codec to be instantiated. When a decoder fails
to initialize it is removed from the list of available decoders and won't be
tried again until the next format change (or until the renderer is disabled).

Note: this change does not affect the renderer capabilities API, as when
checking format support we don't know which codec will be used.

The new method allows to add transfer listeners (e.g. the BandwidthMeter) after
the data source has been created. To simplify the implementation for
subclasses, this change also introduces a BaseDataSource which handles
the list of listeners and the listener registration.

In the future, this allows to register the BandwidthMeter (managed by the player)

From the spec:

If the EXT-X-INDEPENDENT-SEGMENTS tag appears in a Master
Playlist, it applies to every Media Segment in every Media
Playlist in the Master Playlist.

This requires propagation of attributes from the master
playlist to the media playlists. This CL only includes
independent segments, but other inheritable attributes
will be supported in following changes. Other inheritable
attributes include variable substitution definitions and
session keys.

Fix system caption style background being used when cue style is provided.

Currently, we are discarding all TS PES payload readers on seek. This is to fix
a bug that makes PES stream readers read packets inconsistently after seeking (first
time, the readers ignore all packets before PMT, second seek time after PMT is
read, the readers will read all packets before PMT).
This works fine if we don't support seeking to arbitrary position within the TS
stream. However, this may lead to a problem if we want to support seeking, because
some TS streams only have track format at the begining of the stream, and reseting
the payload readers after seeking can lead to track format not available anymore.

This change reverts the original fix (do not discard TS PES payload readers on seek
anymore). Instead, in non-HLS mode, after we have processed all PMTs packets in
the strea, we will re-seek to the beginning and perform readin again to make sure
the result will be consistent across multiple seeks. This is a prepare step to
support seeking in TS streams.
