- Increase the default cache file size to 5MB
- Recommended a minimum cache file size of 2MB to discourage
applications from specifying values small enough such that
unreasonably large numbers of cache files are generated
- Allow maxCacheFileSize=C.LENGTH_UNSET, equivalent to setting it
to MAX_VALUE. This is just for API consistency with other APIs
we have that accept LENGTH_UNSET

CacheEvictor.onStartFile currently receives a length, which is the
maximum size of the content that might be written. The LRU cache
evictor will make sure there's sufficient space for the specified
size. If the actual size of the content is unknown, CacheDataSink
passes maxCacheFileSize.
The current behavior isn't ideal. It seems valid for a developer to
specify maxCacheFileSize=Long.MAX_VALUE if they don't want any
file fragmentation in the cache. However if they then attempt to
cache something with unknown length, LRU cache will try and make
room for content of length Long.MAX_VALUE, and end up evicting the
entire cache to do so.
This change alters the logic so a length is only passed if the
actual size of the content is known. In other cases C.LENGTH_UNSET
is now passed. The LRU evictor will not evict until after the file
is committed. Note a custom LRU evictor could still opt to evict to
ensure some application specified amount of space, if that's the
desired behavior.

This also applies when seeking or transitioning to unprepared media, which
isn't clear from the current documentation.

* Add AC-4 MIME type definition
* Add AC-4 format support in Mp4Extractor and TsExtractor
* Add AC-4 Extractor
* Add AC-4 playback support in MPEG-4, MPEG-DASH, TS and HLS
This is in line with how Player.EventListener and AnalyticsListener methods are
defined and helps to only implement the callbacks needed.

When a Download is created it's set to queued state but doesn't notify
listeners about this state. DownloadManager checks if it can start the
download. After this checks it notifies the listeners.
With this change Download can immediately check if it can be started and
sends correct notification.
