This makes the format metadata null (instead of an empty Metadata
object) when it is not provided, and is therefore consistent with the
other extractors behavior.

Assuming that a flac stream starts with bytes
['f', 'L', 'a', 'C', 0, 0, 0, 0x22] is not always correct as it could
also start with ['f', 'L', 'a', 'C', 0x80, 0, 0, 0x22]
(see https://xiph.org/flac/format.html#metadata_block_streaminfo).

- Fix FLAC extension build (currently broken due to use of std::array,
but fixed by migrating to NDK r20).
- Move opus and ffmpeg extensions to NDK r20. For ffmpeg, upgrade to

LibFlac internally can skip ID3 tags correctly. Therefore, we don't need to keep track of the whole ID3 header section and skip through this section in Java code. We can just set the whole stream to the native library, and it will handle skipping ID3 tags correctly.
The only thing that the Java part need to do is peeking and parsing ID3 tags (if present), in order to populate the track format metadata.

The pending exception will be thrown upon returning to Java

Currently FlacDecoder/FlacExtractor always perform resampling to 16bit. In some
case (with 24bit audio), this might lower the audio quality if the system
supports 24bit audio.
Since AudioTrack implementation supports resampling, we will remove the
resampling step, and return an output with the same bits-per-sample as the original stream.
User can choose to re-sample to 16bit in AudioTrack if necessary.

This allows binding by track type in ChunkExtractorWrapper, which
allows the EMSG and 608 tracks to be enabled on FragmentedMp4Extractor
in DefaultDashChunkSource. ChunkExtractorWrapper currently binds these
to DummyTrackOutputs.
Note: I wanted to pass the mimeType instead, since it's a more specific,
but unfortunately there's at least one place where it's not known at the
point of invoking track() (FlvExtractor).

If/when we add the ability to query version information,
such methods will go into FlacLibrary for consistency with
the other extensions. The difference for Flac is that
since the decoder JNI is used by the extractor too, it
needs splitting into a separate from from FlacDecoder.

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.

underruns in the case that audio is fragmented into many small
buffers.
3. AudioDecoderTrackRenderer now has an overridable method that

- This means DrmInitData is propagated through sample queues (i.e.
is effectively attached to every sample, so we can see when it
changes when reading from the queue).
- It also allows different DrmInitData per track, which is possible
in muxed MKV/WebM, and per Representation for DASH, although we
wont be able to seamlessly adapt in the latter case.
