This is useful to write integration tests for MediaSources which check that the
stream keys returned by getStreamKeys are compatible with the respective manifest
parser.

Problem: There is nothing in the Cache interface that enforces that
these methods are implemented by reading/writing content metadata,
however our own code (CacheDataSource) relies on this property since
it mixes use of [get|set]ContentLength and use of metadata. Using
metadata is the right approach because it minimizes the number of
index writes (e.g. it allows the redirect URI and the content length
to be committed by a single write).
Solution: Remove [get|set]ContentLength, which are redundant anyway,
and use metadata everywhere. Also expose the keys being used through
the public API; there's no particular reason why they shouldn't be.
We previously had an API for getting and setting content length, but
no API for getting and setting redirect uri.

This adds the basic track selection capabilties (including tests).
The new capabilities are not exposed yet through the DownloadHelper implementations
and there will also be more helper methods (e.g. to select multiple audio lanuages at
once).

We currently have two factory methods where it is completely unclear which one needs
to be overridden.
This change deprecates the old one, adds a Util method to easily map back from the new
to the old behaviour, and updates all implementations of the now deprecated method in
our code.

This instantiates the renderers and extract the capabilities. None of the known
renderes incurs any overhead during instantiation.

- Enable GZIP for media playlist + encryption key chunk requests in
HLS, as we do during playback
- Pass around DataSpecs rather than Uris. This will be needed for if
we add manifest cacheKey support (which seems like a good idea for
completeness, if nothing else)

We currently default to not caching data if the content length
cannot be resolved once the DataSource has been open. The
reason for this is to avoid caching progressive live streams.
By doing this we were accidentally not caching in other places
where caching is possible, such as DASH/SS/HLS segments during
playback if the server doesn't include a Content-Length header.
Also HLS encryption key chunks, which were very unlikely to be
cached during playback because we explicitly set FLAG_ALLOW_GZIP
(which normally stops content length from resolving) without
setting FLAG_ALLOW_CACHING_UNKNOWN_LENGTH.
It seems like a good idea to flip the default at this point,
and explicitly disable caching in the one case where we want
that to happen.

This is in line with how Player.EventListener and AnalyticsListener methods are
defined and helps to only implement the callbacks needed.

Moving most of the logic to the base DownloaderHelper helps to implement track
selection for downloading in a single place instead of multiple places.
