The purpose of this change isn't to fix anything. It's just to
simplify things a little bit. There will be following CLs that
make some changes to get things onto correct threads.

This allows to remove the LazyMediaSource used within
DynamicConcatenatingMediaSourceTest and also allows to write test which
simulates dynamic timeline or manifest updates.

This is a step toward retaining a back-buffer in a way that
works for all MediaSource implementations. It's not possible
to adjust the discardBuffer calls in ExoPlayerImplInternal
to discard up to (position - backBufferDurationUs). Next steps
are to:
1. Find an appropriate place to specify the back buffer value,
to be passed to the discardBuffer calls. I guess the
LoadControl is the appropriate place to define such values.
2. Enhance discardBuffer to support a toKeyframe argument to
pass through to discardTo.

Add onEnable() and onDisable() call-backs to TrackSelection. This allows
TrackSelection to perform interesting operations (like subscribe to
NetworkStatus) and clean up after itself.

This will be needed when retaining a back-buffer. Being able to
query the first index allows us to work out when we've discarded
all samples that were obtained from a particular chunk, which
we'll use to determine when to remove chunks from
ChunkSampleStream.mediaChunks.

In the case converting cache files from an earlier version of
SimpleCache, there is no previous version of the index file. If the app
doesn't call any SimpleCache methods which would make the index file
stored before it exists whole data gets lost.

These callbacks are executed on the app thread after the corresponding
timeline update was triggered. This ensures that seek operations see the
updated timelines and are therefore valid, even if the seek is performed into a
window which didn't exist before.

When the renderer media clock source read its stream to end but is not ready,
this means one of two things. Either the next period is not prepared yet and
we need to stop the renderers and buffer until it's prepared, or we are
waiting for another track in the current period with a uneven (longer)
duration.
The second case was already covered by this if condition and uses the standalone
clock instead to continue.
The first case now also uses the standalone clock, but it doesn't make a
difference, because both clocks are stopped and still synchronized.

MPD file may include multiple EventStreams in its Periods, which contains Events
that the application may need to handle/respond to.
This change adds support for parsing the EventStream/Event nodes from MPD
file, and exposing these EventStreams as a metadata sample stream that application
can respond in a similar way to other metadata events.

The mediaChunks.size() > 1 check was supposed to ensure this, and
did roughly the right thing when there was only a single stream
(although it was unnecessarily restrictive in preventing chunk
cancelation for the first chunk, where bytesLoaded != 0 and none
of the samples had been consumed).
Now we have multiple streams the check doesn't do the right thing,
and adding a back-buffer feature will make even more incorrect.
This change switches to checking the condition we actually want
to check directly :).

1. Move Timeline/Manifest into PlaybackInfo
2. Don't update externally visible Timeline/Manifest during preparation
3. Ignore MSG_POSITION_DISCONTINUITY during preparation
4. Correctly set masking variables at start of preparation, and use them
Once this change goes in, PlaybackInfo will contain timeline, manifest
and position, which should always be self-consistent with one another.
The next step would then be to move a bunch of logic in ExoPlayerImpl
that derives state from timeline and position into PlaybackInfo, and
split that into its own top level class that can be easily tested to make
sure it never IndexOutOfBounds.
I think we could also replace the masking variables and instead just assign
a new PlaybackInfo to the playbackInfo variable whenever we're doing
something that requires masking. This should be possible because we no
longer update playbackInfo whenever we have pending acks. It would
require allowing PlaybackInfo to mask the window position internally when
the timeline is empty, but I think this is ok, and again is something we
could test pretty easily.

We don't expect this case to occur, since track selection is
normally expected to check canAcquireSession before selecting
a track. Nevertheless, if an attempt is made to acquire a
session when the media doesn't support the manager's UUID, we
should fail in a more graceful way.

this only works if USE_CHORD_PITCH is false, so remove the constant.

- When transitioning to a new period, the value of bufferedDurationUs
passed to TrackSelection.updateSelectedTrack was incorrectly set to
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.

prepare and selectTracks receive the position from which any
loading should start, where-as continueLoading receives the
actual playback position. These are different in the case that
a previous period is still being played out.
Also removed "relative to the start of the period" from prepare
documentation because it couldn't really be relative to anything
else.

newPlayingPeriodHolder could be set then updated if seeking to a repeated period
that was loaded more than once. This led to MediaPeriodHolders leaking.
Only set newPlayingPeriodHolder once so that any later holders with the same
period identifier get released.
Also add a regression test. FakeMediaSource checks that all created
MediaPeriods were released when it is released.

This change fixes various issues:
- MobileHarness sometimes allocated devices with SDK < 16. As we have no tests running
on these SDKs, a new dimension filter for the mobile_test target ensures that only
devices with SDK >= 16 are selected. A similar filter for SDK version is also added
to the ABR playback tests to ensure no old devices are selected.
- DRM specific tests are skipped for Api < 18, but were not able to run because the
DashTestRunner class tried to link to the MediaDrm constructor. Moved the
constructor to a seperate Builder class to allow execution on Api levels 16 and 17.
- DashWidevineOfflineTest also tried to access code for Api >= 18 without checking
the current level.
- Action implementations which are waiting for events did not ensure that they have a
nextAction to wait for. This caused NullPointerExceptions when this next action was
scheduled.
- DefaultDrmSession always restored the offline keys when a new license was requested,
even if the keys were already restored. These repeated slow calls to restoreKeys
resulted in high numbers of dropped buffers.

Update the audio track selection logic in DefaultTrackSelector:
- When forcing lowest bitrate, use bitrate as tie-breaker when track scores are
the same, prefer the lower bitrate.
- Otherwise, use one of the following values as tie-breaker in order:
- ChannelCount
- SampleRate
- BitRate
If the format being checked is within renderer's capabilities, select it if it
has higher tie-break value, else, select it if it has lower tie-break value.
If all tie-break values are the same, prefer the already selected track.

MediaCodecRenderer implementations require DrmSessionManager<FrameworkMediaCrypto>,
but it's currently not possible for an app to provide a custom implementation due
to FrameworkMediaCrypto having a package private constructor. This change exposes

Calling HandlerThread.quit() or .quitSafely() doesn't immediately terminate
the thread. It just instructs the Looper not to accept any new messages and
to terminate at the next opportunity. Added a HandlerThread.join() everywhere
where the intention is to close and release all resources and to stop all
threads.
