The last selection criteria is the audio bitrate to prefer higher-quality
streams. We shouldn't apply this criterium though if the languages of the
tracks are different.

The app is able to pass a more specialized array type, so the Arrays.copyOf call
produces an array into which it's not valid to store arbitrary AudioProcessors.
Create a new array and copy into it to avoid this problem.

This matches the documentation on MetadataDecoder.decode:
"@return The decoded metadata object, or null if the metadata could not be decoded."

We're no longer tied to the emsg spec, so we can skip unused fields
and assume ms for duration.
Also remove @Nullable annotation from EventMessageEncoder#encode, it
seems the current implementation never returns null

We already allow mixed mime type and mixed sample rate adaptation on request,
so for completeness, we can also allow mixed channel count adaptation.

- When in STATE_SEEK with targetGranule==0, seeking would exit
without checking that the input was positioned at the correct
place.
- Seeking could fail due to trying to read beyond the end of the
stream.
- Seeking was not robust against IO errors during the skip phase
that occurs after the binary search has sufficiently converged.

A previous change switched to calculation of the bitrate based on the
first MPEG audio header in the stream. This had the effect of fixing
seeking to be consistent with playing from the start for streams where
every frame has the same padding value, but broke streams where the
encoder (correctly) modifies the padding value to match the declared
bitrate in the header.

1. Using the Locale on API<21 doesn't make any sense because it's a no-op
anyway. Slightly restructured the code to avoid that.
2. API<21 often reports languages with non-standard underscores instead of
dashes. Normalize that too.
3. Some invalid language tags on API>21 get normalized to "und". Use original
tag in such a case.

2-letter codes (ISO 639-1) are the standard Android normalization and thus we
should prefer them to 3-letter codes (although both are technically allowed
according the BCP47).
This helps in two ways:
1. It simplifies app interaction with our normalized language codes as the
Locale class makes it easy to convert a 2-letter to a 3-letter code but
not the other way round.
2. It better normalizes codes on API<21 where we previously had issues with
language+country codes (see tests).
3. It allows us to normalize both ISO 639-2/T and ISO 639-2/B codes to the same
language.

If we use the default start position, we currently resolve it immediately
even if we need to play an ad first, and later try to project forward again
if we believe that the default start position should be used.
This causes problems if a specific start position is set and the later
projection after the preroll ad shouldn't take place.
The problem is solved by keeping the content position as TIME_UNSET (= default
position) if an ad needs to be played first. The content after the ad can
then be resolved to its current default position if needed.

Adding an explicit option to clear all downloads prevents repeated database
access in a loop when trying to delete all downloads.
However, we still create an arbitrary number of parallel Task threads for this
and seperate callbacks for each download.
PiperOrigin-RevId: 247234181
- Removed DownloadInternal and its sometimes-out-of-sync
duplicate state
- Fixed downloads being in STOPPED rather than QUEUED state
when the manager is paused
- Fixed setMaxParallelDownloads to start/stop downloads if
necessary when the value changes
- Fixed isWaitingForRequirements
PiperOrigin-RevId: 246164845
This resolves some naming confusion that previously existed
as a result of DownloadThread also being used for removals.
Some related variables (e.g. activeDownloadCount) would refer
to both download and removal tasks, whilst others
(e.g. maxParallelDownloads) would refer only to downloads.
This change renames those that refer to both to use "task"
terminology.
This change also includes minor test edits.

- Listener based reporting of progress allows the content length
to be persisted into the download index (and notified via a
download state change) as soon as it's available.
- Moved contentLength back into Download proper. It should only
ever change once, so I'm not sure it belongs in the mutable part
of Download.
- Made a DownloadProgress class, for naming sanity.

Currently SimpleCache will touch cache spans whenever it reads
from them. With legacy SimpleCache setups this involves a potentially
expensive file rename. With new SimpleCache setups it involves
a more efficient but still non-free database write.
For offline use cases, and more generally any use case where the
eviction policy doesn't use last access timestamps, touching is
not useful. This change allows the evictor to specify whether it
needs cache spans to be touched or not. SimpleCache will only touch
spans if the evictor requires it.
Note: There is a potential change in behavior in cases where a
cache uses an evictor that doesn't need cache spans to be touched,
but then later switches to an evictor that does. The new evictor
may temporarily make sub-optimal eviction decisions as a result.
I think this is a very fair trade-off, since this scenario is
unlikely to occur much, if at all, in practice, and even if it
does occur the result isn't that bad.

- Allows enforcing immutability, which in a future CL will allow
avoiding allocating a new array/list on every call.
- Also some left over doc cleanup from the DownloadState rename.
PiperOrigin-RevId: 243627352
- Rename getAllDownloads to getCurrentDownloads to make it clear
that it doesn't include completed and failed downloads
- Change getDownloadCount to isWaitingForRequirements, which is
what it's used for. Added TODO to make it returns the right thing

Non-trivial download state transitions are currently split across
DownloadManager and Download. These transitions are part of the
same state machine, so it's clearer if they're all in the same place
(i.e. DownloadManager, since this is the component that transitions
downloads between states).
