* 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 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.

This option to block bandwidth already exists on the AdaptiveTrackSelection itself
but it's not currently possible to forward the total fixed track bandwidth
automatically.

- Asus ZenFone GO (ASUS_X00AD_2)
- Sugar S9 (i9031)
- Redmi Note 3 (kate)
These devices trigger native crashes similar to

I'm not sure why Asus Zenfone Go (model: ZB500KL, device: ASUS_X00AD_2) was removed here

A remove action will eventually just be the unique ID of the download
that should be removed. This is a step toward that goal.

[Problem]
PAINT-ON mode is not implemented. From the compliance tests:
* RDC command has no effect except to select paint-on style.
* Next data are written directly to the display upon receipt.
* If other captioning is already on the screen, the four-row
limit is still in effect.
[Solution]
It is a rare use case, we do not support overriding characters in
existing cueBuilders as PAINT-ON would require. But several
compliance tests check if the screen is cleared when the mode
switch happens. We must keep the old captions when switching
to PAINT-ON mode
[Test]
- Live Over-the-Air content, beginning of commercials often uses
PAINT-ON mode
- Add DownloadAction.fromByteArray for symmetry with toByteArray
- Make DownloadService call fromByteArray, for symmetry with calls
to toByteArray

We already have tests for comment blocks, and they already
pass because we discard the comment when we fail to parse it
as a cue. We should just skip it directly, however.
This allows more efficient range removals and is consistent with addition,
which supports adding multiple elements in a single operation.

1. Pull up all subclasses of DownloadAction into DownloadAction
2. Add DownloaderFactory for Downloader instantiation, and DefaultDownloaderFactory
to replace the instantiation logic being removed from the DownloadAction
subclasses.
This change will upgrade existing action files gracefully (i.e. it does not
lose compatibility with the existing offline implementation, other than some
minor breaking changes to the API).
TODOs:
1. Move test methods from the XDownloadActionTest classes into DownloadActionTest.
This will be done in a subsequent CL. There's a lot of consolidation that can
be done here, including de-duplicating some of the test code added in this CL.
2. Look at merging DownloaderConstructorHelper into DefaultDownloaderFactory.
3. Use customCacheKey in DASH/HLS/SS Downloaders, for completeness.

Forwarding the listeners to the notification update is meant to ensure we
only notify the listeners which were registered at the time the event happened
However, we currently just copy the reference to the actual list instead of
doing a deep copy of the listeners.
