This typo was introduced in ddb70d96ad
when migrating a static method with parameter `durationUs` to an
instance method where the correct field to use was `blockDurationUs`
(but `durationUs` also exists).
The test that catches this was only added in 45013ece1e (and
therefore configured with the wrong expected output data).

It's unreliable for at least one IMA ADPCM file I've found.
Calculating the blockIndex to seek to using exact properties
also seems more robust.
Note this doesn't change anything for the existing PCM test,
since averageBytesPerSecond is set correctly. It does make
a difference for an upcoming IMA ADPCM test though.

Add support for MP3 as an encoding format for passthrough.
This change does not change the observable
behavior of Exoplayer.
Also name the magics.

- Make extractor output samples that are uniformly distributed
with respect to time, with a target of ~10 samples per second.
The old approach could in theory put every frame into its own
sample, which would be very inefficient downstream because we'd
need to pass them individually to MediaCodec. It could also put
data corresponding to a long duration of time into a single
sample (e.g. if the sample rate of the content is low), which
is bad downstream because we decide whether to set the decodeOnly
flag on a per sample basis. More generally, the new approach
is more predictable :).
- Stop using the WavSeekMap to get sample timestamps, and instead
calculate them directly from the number of frames output. It's
more obviously correct, particularly for data formats like IMA
ADPCM where we'll need to adjust the data prior to output.

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:

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.

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.

- 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 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.

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.

Where media segments are specified using byte ranges, it makes
sense that a server might return 416 (which we don't consider
for blacklisting) if the segment is unavailable, rather than
the 404 (which we do consider for blacklisting) that we expect
when media segments are only specified using a URL.

The Download constructor considers it invalid to have a failure
reason if the download isn't in the failed state. Unfortunately,
calling DefaultDownloadIndex.removeAllDownloads when there's a
failed download will change the state without clearing the reason.
If the downloads are then read back from the DefaultDownloadIndex
we end up violating the Download constructor assertion.
This change clears the failed reason for any existing rows in the
invalid state, and also fixes the root cause that allows invalid
rows to enter the table in the first place.

Without this @Nullable, potential subclasses can't override the
method to return null if they don't want to use the renderer as a
media clock.
