CryptoInfo.iv length is always 16. When the actual initialization vector
is shorter, zero out the trailing bytes.

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 is a nice-regardless improvement to SampleQueue, which will
likely to used to fix the referenced issue. It makes it possible
for SampleQueue subclasses to support dynamic changes to format
adjustment in a non-hacky way.

This method has two use cases:
1. Seeking. Calls are immediately preceded by a call to rewind(), and
the returned value isn't important unless it's ADVANCED_FAILED (i.e.
the caller is only interested in success and failure).
2. Advancing. The return value is important unless it's ADVANCED_FAILED,
in which case the caller wants to treat it as 0.
This change creates separate methods for each use case. The new seekTo
methods automatically rewind and return a boolean. The updated advanceTo
method returns 0 directly in cases where ADVANCED_FAILED was returned.
Arguments that were always hard-coded to true by callers have also been
removed.
This change is a step toward one possible solution for #6155. How we'll
solve that issue is still up for discussion, but this change seems like
one we should make regardless!

- Simulate IO exceptions in the test using FlacBinarySearchSeeker for
seeking in FlacExtractorTests. This makes the test slower but covers
more test cases.

- 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.

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 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.

In MatroskaExtractor, if the last cue time exceeds the duration
specified in the header, then we end up generating a negative
duration chunk as the last item in the SeekMap. We should probably
not do this, so drop it instead.
Note: Matroska does have a CueDuration element, but it's not used
in the one problematic file I've found.

This has been broken since
c3d6be3afd
and broken for ICY (where I noticed the problem) since
5695bae9d8.
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.

- Move property to DrmSession; it feels like a more natural place
for it to go (and provides greater flexibility).

Also remove the "do we really need to do this" comment for AAC.
Parsing from codec specific data is likely to be more robust, so
I think we should continue to do it for formats where we've seen
this problem.
