The number is shelved in calls to queue.clear() to keep it for the next
media period. However, the queue may also become empty by repeated calls to
advancePlayingPeriod which may happen when seeking to an unprepared period.

The new method allows to add transfer listeners (e.g. the BandwidthMeter) after

When getMedatadata from an ExtractorMediaPeriod, due to the MediaPeriod refreshing its Timeline twice, the MetadataRetriever may wrongly reset periodIndex of the current trackGroup to C.TIME_UNSET, which makes it unable to handle subsequent metadata queries.
This CL changes the MetadataRetriever to keep track of periodUid of the current trackGroup instead of period index. PeriodUid is not changed on timeline refreshing, so is not prone the existing problem.

It doesn't really serve a purpose and is not automatically triggered.
Apps need to trigger it manually through

Moreover, the current network type can be obtained by Util.getNetworkType

When the player state is changed from an event listener callback, we may
get recursive listener notifications. These recursions can produce a wrong
order, skip or duplicate updates, and send different notifications to
different listeners.
This change serializes listener notifications by clustering all update data
in a helper data class and adding the updates to a queue which can be handled
in a loop on the outer layer of the recursion.
As playWhenReady updates also reference the current playbackInfo, we need to
redirect the listener notifcations for setPlayWhenReady to the same queue.

A new playback nonce is created for each playback of the same item. Thus we
need to inject the nonce dynamically into the data source factory.
This CL adds the DataSource which does the actual insertion into the request
URLs and a MediaSource which listens to new media periods, to request the
nonce and to configure the data source factory for this media period to use
this nonce.

flat list of Formats.

This was adding a lot of code, and the multiple use cases
for Downloader was pretty confusing (in particular the
ordering of method calls was unclear). It's also not
performant (e.g. it requires loading/parsing manifest(s)
and initialization segments from disk).
In practice I think apps will need to keep a record of
what's offlined in their app's database (or equivalent),
which they can update by registering as a listener on
DownloadManager. This will be done for the demo app in
a subsequent change.

ProgressiveDownloader never implemented this properly, and we
