This CL adds support for seeking witin TS streams by using binary search. For
any seek timestamp, it tries to find the location in the stream where PCR
timestamp is close to the target timestamp, and return this position as the
seek position.

- Use ConstantBitrateSeeker to implement seeking for ADTS format. Since most
ADTS streams are VBR, we use the average bitrate of the first 1000 frames as
the average bit rate.

When user seeks to an unprepared period, since there is no period being played, currently the track groups and track selections are still the ones from previous period. This CL changes it so that when such seeking happens, PlaybackInfo's track groups and track selections are changed to empty.

MatroskaExtractor was checking for INDEX_UNSET as the sample count for buffers
not containing syncframes, but actually 0 was returned for these. Theoretically
this could prevent us starting to play a TrueHD stream as we wait until we can
read the sample count from a syncframe before accepting the audio in
DefaultAudioSink, but it seems that rechunking avoided this issue arising in
practice.

The looping media source doesn't convert the media period id to the externally
visible media period id. And the merging media source reports media period
creations multiple times which will break listeners assuming a media period
with a specific id will only be created once.
Also amend the doc for MediaSource.createPeriod to reflect that media periods
created in parallel do not actually have the same id.

Period transitions with non-zero start position happen too early as the
playing period is advanced as soon as the renderer offset is reached not
taking into account that the start position needs to be added to that.

While the timeline is empty, we keep a dummy MediaPeriodId in PlaybackInfo with
a period index of 0. We leak this MediaPeriodId in actual use in these
situations:
1. When issuing an IllegalSeekPosition after preparation. The timeline becomes
non-empty, but the media period id stays at its dummy value.
2. When re-adding sources to a previously empty timeline. The dummy period id
is used as the start position for the new non-empty timeline.
This change makes:
- the constructor of PlaybackInfo using those dummy values more explicit
- prevents the issues above by using the correct default position in the new
non-empty timeline for the above mentioned cases.

The new method allows to add transfer listeners (e.g. the BandwidthMeter) after

When getMedatadata from an ExtractorMediaPeriod, due to the MediaPeriod refreshing its Timeline twice, the MetadataRetriever may wrongly reset periodIndex of the current trackGroup to C.TIME_UNSET, which makes it unable to handle subsequent metadata queries.
This CL changes the MetadataRetriever to keep track of periodUid of the current trackGroup instead of period index. PeriodUid is not changed on timeline refreshing, so is not prone the existing problem.

Moreover, the current network type can be obtained by Util.getNetworkType
