This is in preparation for adding an internal-only change near these
lines.

These are not useful for estimating the network speed and should be
ignored.

The DedicatedThreadAsyncMediaCodecAdapter is an
asynchronous MediaCodecAdapter that routes callback
to a separate Thread.

This may happen for example when trying to load unfinished live media
chunks that can only be loaded at real-time playback speed.

The flag can be used by the sources to indicate that network transfer
will knowingly be throttled, such that transfer listeners like the
bandwidth meter can take this information into account.

Also change IcyInfo.rawMetatadata from String to byte[]

ICY doesn't specify the character encoding, and there are streams
not using UTF-8 (issue:#6753). It seems the default of at least one
server is ISO-8859-1 so let's support that as a fallback:
https://github.com/savonet/liquidsoap/issues/411#issuecomment-288759200

Also update IcyDecoder to skip strings it doesn't recognise at all
instead of decoding invalid characters.

The feed from issue:#6753 now decodes accents correctly:
EventLogger:   ICY: title="D Pai - Le temps de la rentrée", url="null"

This is a useful test to see if it works well in a real situation.

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 Normalizes some short codes that have been superseded by macrolanguage codes by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.
