As per the spec of MediaPeriod.getDurationUs, when a live
stream ends we need to start returning the correct final
duration.

We were forgetting to reset renderers during track
selections where muxed media is used.

It's only "needed" for HLS, and this requirement will
go away soon. It's safe to remove the flag ahead of
this because a TrackSelector can/should not attempt to
adapt between multiple audio/text tracks.
Also remove unnecessary restrictions on TrackGroups
being non-empty and only of known types.

- TrackSelection now exposes the selected formats, ordered
by decreasing bandwidth. This removes the need for DASH,
SS and HLS to do the sorting individually.
- The change also removes the need to reconstruct TrackSelection
instances with a different group index in various places
(e.g. MergingMediaPeriod).
- This is also a step toward potentially packaging the
FormatEvaluator inside of the TrackSelection (TBD).

According to the spec, there is no mandatory relation between segments'
sequence numbers of different variants. This CL ignores sequence numbers
when switching variants:
* In vod, the switching playback position is obtained by adding the
duration of previous segments.
* In live playback this is not possible. It is assumed that the
different live media playlists do not drift apart too much, so
the playback position is obtained by subtracting the duration
in reverse order.
In later CLs, the described mechanisms will become the fallback methods
by replacing them with the use of EXT-X-PROGRAM-DATE-TIME information
or more reliable sources.

SmoothStreaming -> Ss
MediaPresentationDescription -> DashManifest
DashSingleSegmentIndex -> SingleSegmentIndex
Moved DASH and Ss manifest classes to matching
manifest packages for consistency. For Hls the
package is called playlist still, since that's
what they're widely known as.

This also removes direct use of HttpURLConnection and
allows use of any HttpDataSource for license requests,
which means those using OkHttp can finally use the
same network stack for license requests as they're using
for everything else, without having to implement their
own callback.

This was possible previously, but now we support things
like multi-period DASH we need to do the injection in
the form of factories rather than concrete instances.

DashMediaPeriod.releasePeriod resets duration to 0, but
instances are currently being re-used through multiple
prepare/release cycles. Hence the duration needs to be
retained. This change fixes this issue, and also makes
variables final in DashMediaPeriod where possible.

1. Rename "extensions" package to "decoder". It's used by both
text and (should be used by) metadata, so it's no longer just
for extensions.
2. Move Buffer objects move into the decoder package.
3. Rename SubtitleParser and MetadataParser to SubtitleDecoder
and MetadataDecoder respectively, since they extend Decoder.
Ditto for all subclasses.
4. Subtitle and Metadata decoders now throw their own exception
types rather than ParserException.
5. Move MediaCodec classes into a mediacodec package, with the
exception of the concrete audio and video renderers.
6. Create an audio package to hold the two audio renderer classes
plus related util classes.
7. Create a video package to hold the one video renderer class
plus related util classes.
After this change the following nice properties hold:
1. Want a video renderer? Look in the video package. Ditto for
audio, text and metadata.
2. All TrackRenderer implementations use a decoder of some kind
to decode buffers received from the source, so we have
consistent terminology there.

It doesn't look like TrackSelectionPolicy is going to be
useful other than with DefaultTrackSelector, and it's kinda
confusing dealing with both "selector" and "policy"
terminology. This change does the following:
DefaultTrackSelector -> selector.MappingTrackSelector
DefaultTrackSelectionPolicy -> selector.DefaultTrackSelector
TrackSelectionPolicy -> [deleted]

- BehindLiveWindowException is a source exception.
- SequenceableLoader is related to sources.
