A previous change switched to calculation of the bitrate based on the
first MPEG audio header in the stream. This had the effect of fixing
seeking to be consistent with playing from the start for streams where
every frame has the same padding value, but broke streams where the
encoder (correctly) modifies the padding value to match the declared
bitrate in the header.

* Add AC-4 MIME type definition
* Add AC-4 format support in Mp4Extractor and TsExtractor
* Add AC-4 Extractor
* Add AC-4 playback support in MPEG-4, MPEG-DASH, TS and HLS
The buffered position is currently based on the mimimum queued timestamp of
all AV tracks. If the tracks have unequal lengths, one track continues loading
without bounds as the "buffered position" will always stay at the shorter
track's duration.
This change adds an optional buffer flag to mark the last sample of the
stream. This is set in the Mp4Extractor only so far. ExtractorMediaSource
uses this flag to ignore AV streams in the buffered duration calculation if
they already finished loading.

- Increase the search window size to fix TS seeking for problematic
media we've had provided to us.
- As per my comments on the issue, we should look at doing more here
to better fix the problem. This will solve the worst of the
immediate problem, however.
- The memory usage is non-trivial, particularly with the increased
search window size. I've made the allocations only live whilst
determining duration and seeking to address this. I've done the same
for PS just for consistency.

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.

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

Add supports for reading duration for a PS stream by reading SCR values from
the header of packs at the start and at the end of the stream, calculating the
difference, and converting that into stream duration.

[Problem] Sarnoff spec complaince tests streams are MPEG2 TS.
Currently, parsing CC data from MPEG2 TS is not supported
[Solution] Parsed CC data from MPEG2 stream because all Sarnoff streams are MPEG2
Add supports for reading duration for a TS stream by reading PCR values of the PCR PID packets at the start and at the end of the stream, calculating the difference, and converting that into stream duration.

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.

1. Allow retaining a decoder without any reconfiguration, in addition
to retaining with reconfiguration (and not retaining)
2. Fix retention logic for video decoders to take into account changing
ColorInfo
3. Allow retention of audio decoders when possible

There are 4 tests which can't currently be moved:
- DownloadManagerTest explicitly uses the main looper which isn't easily
supported because the test runs on this thread.
- ContentDataSourceTest uses an AssetFileDescriptor which wraps a
ParcelFileDescriptor. It seems Robolectric doesn't correctly forward the
inner wrapped file descriptor leading to NPE.
- CacheContentIndexTest and SimpleCacheSpanTest both work fine with Gradle
but fail with seemingly valid test failures on Blaze.
