The nullness checker complains about Integers with @IntDef annotations
so replace pairs with custom pair types for the timed event records in
PlaybackStats.

Caveats:

- Block additional data is ignored if the block is laced
  and contains multiple samples. Note that this is not
  a loss of functionality (SimpleBlock cannot have block
  additional data, and lacing was previously completely
  unsupported for Block)

- Subrip and ASS samples are dropped if they're in laced
  blocks with multiple samples (I don't think this is
  valid anyway)

Issue: #3026

This change constrains the use of sample state member variables to
writeSampleData, finishWriteSampleData and resetWriteSampleData.
Using them elsewhere gets increasingly confusing when considering
features like lacing in full blocks. For example sampleBytesWritten
cannot be used when calling commitSampleToOutput in this case
because we need to write the sample data for multiple samples
before we commit any of them.

Add peek() method to ExtractorInput

Move MediaCodeAdapter and implementations to separate
files and add unit tests for AsynchronousMediaCodecAdapter.

Flac streams exist but are not commonly used. Also, they are not
supported by the FLAC extension extractor.

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.

The capture frame rate is currently available both via Format.metadata
and decoded in Format.frameRate. As the container Format.frameRate may
be useful to apps, only store the capture frame rate in metadata (apps
will need to decode it but can now access the container frame rate too).

For AOSP TV devices that might not pass manual verification.

- Remove "lacing" from member variables. They're used even if
  there is no lacing (and the fact that lacing is the way of
  getting multiple samples into a block isn't important).

Issue: #3026
PiperOrigin-RevId: 284152447

- Change sampleHasReferenceBlock to a block reading variable, which is
  what it is (the distinction didn't matter previously, but will do so
  when we add lacing support in full blocks because there wont be a 1:1
  relationship any more.
- Move sampleRead to be a reading state variable.
- Stop abbreviating "additional"

An I/O error could occur while handling the start of an mdta box, in
which case retrying would cause another ContainerAtom to be added. Fix
this by skipping the mdta header before updating container atoms.

Also remove getRendererCapabilities arg that's now always null.

This makes the exception easier to interpret and helps with debugging of
externally reported issues.

Saves around 200 lines of code. High level overview:
- Rename SampleQueue to SampleDataQueue.
- Rename SampleMetadataQueue to SampleQueue.

This CL should not introduce behavior changes. The only significant
changes in synchronization should be:
+ Add synchronized keyword to isReady.
  - Seems to be necessary.
+ Add synchronized keyword to SampleQueue.sampleMetadata.
  - Before this change, SampleQueue.sampleMetadata could acquire the
    SampleMetadataQueue lock three times in a single method call.

Other miscellaneous improvements:
+ Put all private methods at the bottom.
+ Move release() to the right category.
