This version only supports 16-bit uncompressed PCM. A follow-up CL will
add support for other sample bit depths.

If this situation is encountered, we assume that the encoder has a good reason to
do this and use the last pts + frameDuration as new pts.

- Remove special DefaultTrackOutput.sampleData method, and have
SingleSampleMediaChunk use the regular one instead.
- Make DummyTrackOutput behave correctly is allowEndOfInput is
false.
- Simplify progress tracking in ExtractorSampleSource.

This is the first version and is still not linked to the WebVTT parser nor
does it support all the intended features, but it was left this way to
ease the review a little bit.

When showing a track selection for a renderer, the override
variable could end up being retained from some previous call
to show a track selection for some other renderer.

until after the extensions themselves are brought across.

When the ctts contained an entry that had a 0-valued entry count, the
parser would miss every other entry, failing the final assertion.
The standard does not seem to prevent the value 0 in the sample_count
field, so we need to allow it.

When the edited sample sequence does not contain any sync sample Exoplayer does not provide
support. This CL changes the ArrayIndexOutOfBoundsException for a more explicative
ParserException.

The MP4 standard considers the udta box as a regular container box. Quicktime, however,
considers it as a container (of only leaf atoms) that can have a terminating 32 bit
integer with value 0. Since this breaks the principle of not having content in container
boxes, this CL considers the udta box as a leaf box that contains other boxes and does
the parsing manually.

The parsing of multiple moov boxes for a single ExtractorOutput incurred in
an assertion failure due to repeated track declarations. This CL makes each
new moov box replace any previous one. This change is transparent to the
client, no flags are provided to allow this feature.

If a container box is empty, it is never removed
from the container box stack, breaking the extractor.

- Made enabledRenderers an array to avoid loads of method calls.
- Made if so that enabled renderers are always called in a consistent
order, rather than their order changing if they're enabled/disabled
over time. This is likely to make performance more predictable.
- Split out reading of resets into a separate method. This method is
now called directly after seeking on the source, so as to ensure
instant propagation of the new position from source->renderers in
the common case.

Some devices fail to decode an avc3 stream that doesn't start with an SPS (for
example, if an access unit delimiter appears first). Workaround the issue by
discarding input sample data up to the first SPS on those devices.

When reading unknown duration files with CBR seeking, the Mp3Extractor could
try to read sample data from 0. This happened because synchronization did not
skip over the ID3 data when it immediately found valid frames. When the invalid
sample data is read, the extractor tries to resynchronize from the next byte
(at offset 1), and this fails because the ID3 data at the start of the file is
longer than the synchronization search distance.

This is needed to support fully demuxed audio in HLS. For the
sample I have the video (only) variant still declares an AAC
stream. I suspect there's at least one toolchain out there that
hardcodes H264 and AAC streams in TS output.

The idea here is that you'll be able to feed data through an extractor
to a FakeExtractorOutput, then do the same again with some or all of the
simulated flakiness settings toggled on FakeExtractorInput, and then
assert that the output was the same in both cases.

The upstream source (or its stream) should always provide data
starting from a sync frame, so this logic shouldn't be necessary.

allow "center".
This value (and not "middle") is listed in
https://w3c.github.io/webvtt/ ( WebVTT: The Web Video Text Tracks Format, Draft
Community Group Report, 21 December 2015).
Leaving the behavior for "middle" unchanged.
It was the value listed in older drafts, e.g.
https://www.w3.org/TR/2014/WD-webvtt1-20141113/ ( W3C First Public Working
