We previously used Locale.fromLanguageTag and then toLanguageTag to automatically
filter out invalid tags and to replace deprecated tags. However, this only works
for API 21+.

This change does no longer rely on the platform methods and instead:
 1. Keeps invalid tags as they are. This may help if developers rely on
    non-spec-complaint language tags (for example, #6681).
 2. Adds a list of deprcated tags and their modern replacements to our code
 3. Normalizes some short codes that have been superseded by macrolanguage codes by
    their macrolanguage equivalent.

Document that limit() is respected, but position() and arrayOffset()
are assumed to be zero.

This has been broken since
https://github.com/google/ExoPlayer/commit/c3d6be3afdd7c0ca68dba15e443bc64aa3f61073
and broken for ICY (where I noticed the problem) since
https://github.com/google/ExoPlayer/commit/5695bae9d8fde5e156fd38fa552e266c5611c71f.
ICY symptom is that we see no repeated metadata, because the
Icy-MetaData:1 header doesn't make it to the server so we never get back
icy-metaint.

The presentationTimeOffsetMs may be C.TIME_UNSET for VOD content
and shouldn't be used in calculations for the windowStartTime.

Retrieve the sample number in the extractor instead of passing a holder
to FlacBinarySearchSeeker. This change makes the code easier to
understand and is required to implement the seeking from the seek table.

- Create PcmOutputWriter for PCM.
- In a future change an ImaAdPcmOutputWriter will be introduced
  for IMA ADPCM support.

- WavHeader is now immutable and contains only values parsed out
  of the WAVE FMT chunk. It no longer contains a C.PcmEncoding
  encoding, or mutable data bounds.
- WavHeaderReader now parses the WAVE header chunks without any
  additional logic (e.g. validating the block alignment value,
  which is format type dependent).
- The SeekMap part of WavHeader is split out into WavSeekMap.

This returns the current offset to the live edge. The calculation is
non-intuitive enough to provide this convenience method.

This was verified as a no-op change in a prod experiment.

This avoids needing to jump through type paremeter hoops to create a
sub-classable Cue.Builder.

Cue should have a standard set of fields, because it will be
consumed by renderers that don't know what type it is. The
existing subclass fields are only used inside their respective
packages, so can be part of a wrapper object instead.

This lays the groundwork for converting Cue's multiple constructors
into a Builder pattern.

ImaAdsLoader relies on preloading being enabled (it doesn't
work without it) so we may as well remove the constant to
avoid potential confusion.

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