If there is data after the last samples in the container, we may request
continue loading after the last samples have been read but before the load has
completed. In this situation the buffered position is returned as
Long.MAX_VALUE, which prevents continuing loading, yet the media period is not
treated as fully buffered because its buffered position is not
C.TIME_END_OF_SOURCE.

We can keep the reading media period and continue playing if we haven't read
beyond the new duration. Otherwise, we can keep the period, but need to reset
the renderers as we already read too far.

On older API levels it's also necessary to implement
openOrCreateDatabase, to be called by SQLiteOpenHelper.

It better describes what the class does. More importantly, we've had
inconsistent class names since we added offline support, for which we
added ProgressiveDownloader ("ExtractorDownloader" doesn't make any
sense). We could really do with aligning the names for clarity.

These methods take a list of languages to be downloaded and add selections for
each of the languages.

The subclasses only call specific constructor combinations and can easily
replaced by static methods.

This requires to prepare the media source and the periods in a small helper similar
to the metadata retriever. It also gets rid of the need to have abstract protected
methods to load the manifest, to extract the track groups and to convert to stream keys,
as this can now be handled by the media period.

Currently, we remove all variants if none of the stream keys contains any
variants. This causes HlsMediaPeriod to throw exceptions as it expects at least
one variant.

Change it to support master playlists without variants.

Converting a single track selection to stream keys is only possible if the output
is independent from other track selections being made.

This is not the case for DASH and HLS embedded track groups which should select the
already selected primary track if possible (and thus needs to know  whether a primary
track group is selected).

Also, update the test method to take a period index.

This should be removed after releasing.

The way it is currently, it's very unclear that an operation on the
version table will correctly belong to a transaction in code such as
this, taken from DefaultDownloadIndex:

writableDatabase.beginTransaction();
try {
  writableDatabase.execSQL(...);
  versionTable.setVersion(...);
  writableDatabase.setTransactionSuccessful();
} finally {
  writableDatabase.endTransaction();
}

This change explicitly passes the database, to make it obvious that
the operation will really go into the same transaction:

writableDatabase.beginTransaction();
try {
  writableDatabase.execSQL(....);
  VersionTable.setVersion(writableDatabase, ...);
  writableDatabase.setTransactionSuccessful();
} finally {
  writableDatabase.endTransaction();
}

Goal: reduce binary size.

Float output is only possible from API 21, but the high-res int
to float conversion path was checking for 32-bit PCM not float
output capability.

This will allow CachedContentIndex to start using database
storage without us having to change the SimpleCache and
CachedContentIndex constructors to require a Context or a
DatabaseProvider.

This brings in a memory leak fix.

Issue: #4114

If are allowing changing durations of periods, we shouldn't use the end position
of clipped content as part of the id as it may change. This change moves the end
position back to MediaPeriodInfo and adds the next ad group index to the id
instead to ensure we still have unique ids for all content parts.

The combination of pre-16 API levels accounting for ~0.5% of the device
population, and that the most important components in ExoPlayer (e.g.
the MediaCodec renderers) have always required API level 16, mean it's
very unlikely this will negatively impact on anyone.

This interface will get an SQLite implementation in a subsequent CL

We need to support serialization to/from an SQLite table. The
model of passing something around for each class to write into
doesn't work well for SQL, and it would be messy to have two
different structural designs for serialization. This change
centralizes the logic in CachedContentIndex, where a centralized
SQL based version can more easily sit alongside it.

This method is a generalization of the existing hasReadStreamToEnd. It is
useful to determine whether a renderer already read beyond a new duration of
a period.

Necessary in two scenarios:
+ When the demo app starts casting to a receiver app that already
  had a queue.
+ When two demo apps are connected to the same receiver app and
  both make modifications.

1. The method kept track of the current period index to check if the next
period is still in the correct period. This is unneccessary since we no longer
use the period index but the actual uid in MediaPeriodId and mismatches are
already detected by canKeepMediaPeriodHolder.
2. We updated the MediaPeriodIndfo twice: once in getFollowingMediaPeriodInfo
and once in getUpdatedMediaPeriodInfo. That's confusing and difficult to
follow. The only difference is that getUpdatedMediaPeriodInfo keeps the
content position while getFollowingMediaPeriodInfo resets it. This is made more
explicit for readability.
3. The durations compatibility check for all following periods was broken as
it compared the same durations (partly due to the confusion caused by 2.)
