This aligns mkv with mp4, flv and ts extractors.
This issue was found when AAC in an MKV container was not offloaded
as format.codecs was null.

The sample timestamps are currently rounded to milliseconds, only to
be multiplied by 1000 later. This causes rounding errors where the sample
timestamps don't match the timestamps in the seek table (which are already
in microseconds).

This change generalizes the concept of "reading parameter sets" to
"reading prefix NAL units", ahead of a change that will treat AUD
and suffix SEI NAL units in the same way.
The change also introduces some static isXxxNalUnit methods for
clarity.

If the start time of the edit falls within a sample, start from that
sample rather than the next one. This ensures playback can start from
the correct point if the sample is a keyframe, rather than having to
start from the next one.

- Deprecate old Format.createXXX methods
- Deprecate most Format.copyXXX methods
- Stop using deprecated Format.copyXXX methods in the library
Note: Replacing library usages of Format.createXXX method
will be done in follow up CLs. These changes aren't purely
mechanical because we need to decide which out of peakBitrate
and averageBitrate to set in each case where currently a
single bitrate is provided.

It's not clear why we're currently outputting the format in both init()
and consume() - it seems likely that this was accidentally introduced
in <unknown commit>
when we started outputting the format in consume() but didn't remove it
from init().
The SCTE-35 TsExtractorTest doesn't pass with the current code because
when it seeks back to the beginning of the file init() is not called
again so the second pass through only sees one sample (and
ExtractorAsserts checks that seeking back to 0 produces the same output
as reading the file from the beginning).
I generated the SCTE-35 sample using TSDuck's tsp command:
$ tsp --add-input-stuffing 1/10 \
-I file testdata/src/test/assets/ts/sample.ts \
-P pmt --service 1 --add-programinfo-id 0x43554549 --add-pid 600/0x86 \
-P spliceinject --service 1 --files scte_35.xml --wait-first-batch \
-P filter --negate --pid 0x1FFF \
-O file testdata/src/test/assets/ts/sample_scte35.ts
This was adapted from the instructions in section 5.2.24.1 of the TSDuck
user manual: https://tsduck.io/download/docs/tsduck.pdf

Not important, but when overriding a method that can return null,
it seems preferable to put @Override first, followed by what it's
overriding (which includes the @Nullable).
Also remove explicit @NonNull use in the core library. @NonNull is
propagated by default, so this is redundant.

Modify TrackOutput.sampleData() to accept SampleDataReader instead of ExtractorInput. SampleDataReader supports only read and skip calls, which all sampleData() implementations already restrict themselves to.

The functional change is to set the bitrate fields to Format.NO_VALUE
in the case that they're non-positive in the header data. Else it's
very easy to to take the fields and copy them directly into Format as
incorrect values.
Issue #2863

Passing EXT-X-KEY DrmInitData through the FragmentedMp4Extractor
doesn't work for streams with key rotation, because an extractor
instance is used for multiple segments, but is only passed the
EXT-X-KEY DrmInitData corresponding to the first segment.
This change removes passing DrmInitData through the extractor,
and instead passes it via FormatAdjustingSampleQueue. This is
in-line with how manifest DrmInitData is handled during DASH
playbacks.

This seeker is only seeking to frames that have already been read by the
extractor for playback. Seeking to not-yet-read frames will be
implemented in another change.
