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.

When a reset is pending the sample queues normally contain pre-seek
samples (which will be emptied when a pending load is canceled). The
position passed to discard will be a post-seek position. I don't
think anything bad happened in any of the cases being changed, but
discarding is unnecessary in such cases, and reasoning about such
cases is difficult.

For background on why doing this works, see below. I don't want to change
how we get our Cipher instance in non-test code, since PKCS7 always works
on Android. It's only when the tests are running on a non-Android host
machine that they can fail. An alternative would be to make it an androidTest,
but androidTests are slow.
------
Background:
"While Java considers PKCS5 and PKCS7 padding to be the "same" (and
one should always use the string "AES/CBC/PKCS5Padding" because
"AES/CBC/PKCS7Padding" will cause NoSuchAlgorithmException to be thrown
when initializing an AES block cipher using the Java crypto API), I
consider this a gross misnaming in the Java platform because the pure
technical definitions of these paddings are not the same."

If a MediaPeriod uses a Loadable, then there are typically
reference chains of the form:
LoadingThread[GCroot]->Loadable->MediaPeriod->Player
Where the player is the MediaPeriod callback. When the
player is released, this reference chain prevents the
player from being GC'd until Loadable cancellation
completes, which may not always be fast. This in turn
will typically prevent the application's activity from
being GC'd, since it'll normally be registered as a
listener on the player (directly or indirectly via
something like a view).
This change mitigates the issue by removing references
that the MediaPeriod holds back to the player. The
MediaPeriod will still not be eligible for GC, but the
player and application activity will be, which in most
cases will be most of the leak (in terms of size).

This was adding a lot of code, and the multiple use cases
for Downloader was pretty confusing (in particular the

For VOD streams the window position in the period was the program date time.
This change makes period and initial window positions match. For live streams
the window position advances as segments are removed, so its position in the
period is the difference between the initial program date time and the program
date time of the latest playlist.
This also makes it possible to insert ads in VOD HLS content with program date

Releasing the player released the internal playback thread once renderers were

We've found that in our production environment, the AAC stream's timestamp exceeds the 33bit limit from time to time, when it happens, `peekId3PrivTimestamp` returns a value that is greater than `TimestampAdjuster.MAX_PTS_PLUS_ONE`, which causes a overflow in `TimestampAdjuster.adjustTsTimestamp` (overflow inside `ptsToUs`) after playing for a while . When the overflow happens, the start time of the stream becomes negative and the playback simply stucks at buffering forever.
I fully understand that the 33bit is a spec requirement, thus I asked our stream provider to correct this mistake. But in the mean time, I'd also like ExoPlayer to handle this situation more error tolerance, as in other platforms (iOS, browsers) we see more tolerance behavior.

0. It should have been set to correctly reflect buffered media in
previous periods still being played out.
- This change fixes the issue described above, and also propagates the
playback position through to this method. The position of the next
load within the period can be calculated by adding the position and
bufferedDurationUs.

Also create helper method in HlsMasterPlaylist to allow the copying of
the playlist to another, but with the variants reordered based on a
passed comparator. Also added an implementation of HlsPlaylistParser
which will reorder the variants returned.
Follow-up on the update to ABR logic in AdaptiveTrackSelection for live
streaming case:
- Do not reset liveEdgeTimeUs when user seek to a different position.
- For HlsChunkSource, for non-independent segments, currently the
bufferedDuration calculate will subtract previousChunk's duration. So to make
it work with live-streaming ABR logic, we subtract timeToLiveEdgeUs a similar
amount to compensate for that operation.
- Minor update to DefaultSSChunkSource, only perform TrackSelection when needed
(after checking necessary conditions).

In live streaming, if the playback position is very close to live edge,
the buffered duration will never reach minDurationForQualityIncreaseMs,
which prevents switching from ever happening. So we will provide the
durationToLiveEdgeUs to AdaptiveTrackSelection in live streaming case,
so it can handle this edge case.

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

This parameter is used by methods such as getNextWindowIndex
and getPreviousWindowIndex to determine the playback order.
Additionally, there are method to query the first and last
window index given the shuffle mode.
None of the timeline implementations nor the ExoPlayer
implementation supports shuffling so far.

When resetting a SampleQueue, by default the upstream format
is not cleared. This is necessary for progressive playbacks,
since (a) the formats never change, and (b) the extractors
only output them once. So when a seek occurs, it's necessary
to clear all sample data from the queue, but retain the current
upstream format.
Uniquely for HLS, the media in a SampleQueue that we may read
from can be in a format not supported by the consuming renderers.
We clear all the sample data from the queue in this case, but
not the upstream format. Since we have an optimization that
allows the upstream format to be read in advance of another
sample being written into the queue, this can result in an
unsupported format being read by a consuming renderer. This
change ensures the upstream format is correctly cleared in the
problematic case.

This CL aims that the player fails upon:
- Playlist that don't change in a suspiciously long time,
which might mean there are server side issues.
- Playlist with a media sequence lower that its last snapshot
and no overlapping segments.
This two error conditions are propagated through the renderer,
but not through MediaSource#maybeThrowSourceInfoRefreshError.

It's currently difficult to use ExoPlayer modules in other gradle
projects because they rely on constants and dependencies defined
in our own top level gradle file. This change moves the constants
into a separate file referenced directly from each module. It also
removes the need for the top level gradle file to declare a
dependency on com.novoda:bintray-release. This is now only needed
if "exoplayerPublishEnabled = true" is specified.

Currently, media is discarded from DefaultTrackOutput
and SampleMetadataQueue as soon as it's been read. In
upcoming changes we'll decouple discard and read. This
will make it possible to retain already-read media in
these buffer classes, and allow the read position to
be moved backward as far as media is retained. This is
important for fixing an edge case around 608/EMSG
tracks, and could also underpin future features like
allowing retaining of X-seconds past media in the
buffer.
This change renames some variables and methods to
prepare for the upcoming changes. read/write indices
are renamed to start/end. The upcoming changes will
add a read index that's between the two. isEmpty is
inverted and renamed to hasNextSample, since it will
be possible to not have a next sample (because the
read index == end index) but for the buffer to not
be empty (because start index < read index).

As this is not happening here, the attributes can be removed.

This fixes transitioning into the ended state if we see
endOfStream from the chunk source whilst in the pending
reset state. Prior to this fix we'd still be pending a
reset, and so readData would never allow EOS to be read
by the consuming renderer.

This change also ensures that format changes are read whilst the
renderer is enabled but without a codec. This is necessary to
ensure the drm session is updated (or replaced).
Updating the format is also needed so that the up-to-date format is
used in the case that the codec is initialized later due to the
surface being set. Previously, if an ABR change occurred between
the format being read and the surface being attached, we would
instantiate the codec and then immediately have to reconfigure it
when as a result of reading the up-to-date format. For a non-adaptive
codec this resulted in the codec being immediately released and
instantiated again!
