In some occasions, we may want to discard a part of the buffered media to
improve playback quality. This CL adds this functionality by allowing the
loading media period to re-evaluate its buffer periodically (every 2s) and discard
chunks as it needs.

FakeRenderer only needs to allocate real memory because it extends BaseRenderer
which uses the actual SampleStream implementation. Immediately release the

simulations.

Calling it directly might skip other callbacks. For example:
ActionSchedule.Builder().waitForTimelineChanged(...).build().
is currently immediately calling through to
callback.onActionScheduleFinished when the timeline changes.
Depending on the position of the action schedule listener in the
listener set, it may skip other listeners also
listening to timeline changes.

The ExoPlayerImpl implementation forwards the stop request with this optional
parameter. To ensure correct masking (e.g. when timeline updates arrive after
calling reset in ExoPlayerImpl but before resetInternal in
ExoPlayerImplInternal), we use the existing prepareAck counter and extend it
also count stop operations. For this to work, we also return the updated
empty timeline after finishing the reset.
The CastPlayer doesn't support the two reset options so far.

A message to stop the playback and to quit the playback thread was posted in release().
The stop message removed all other already queued messages which might include
the second message to quit the thread. That led to infinite waiting in the
release method because the playback thread never got the quit signal.

Fixed by explicitly waiting for the timeline update. This shouldn't be
necessary and will be removed as soon as the correct order of events
can be guaranteed (timeline change -> state change -> onSeekProcessed).
The waiting for the timeline update is implemented by introducing the
feature that the test runner also waits until the action schedule has
finished before stopping the test.

In a test run where no exceptions were thrown on the main thread and the test
did not time out, exceptions from onPlayerError were not correctly propagated to
the test thread (handleException would be called with null).
Fix ExoPlayerTestRunner.onPlayerError to propagate the actual exception from the
player.

Currently onTimelineChanged doesn't allow to distinguish easily between the
different reasons why it's being called. Especially, finding
out whether a new media source has been prepared or the current source
refreshed dynamically was impossible without tightly coupling the player
operations with the listener.
The new reasons provide this disdinction by either indicating a newly
initialized media source, a dynamic update to an existing timeline
or manifest, or a reset of the player (which usually results in an
empty timeline).
The original onTimelineChanged method without reason is kept in the
DefaultEventListener as deprecated to prevent the need to update all
existing listeners in one go.

currently used in DynamicConcatenatingMediaSourceTest, so it

- 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.

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.

MediaPeriods were released when it is released.

The chunk size of real video data varies around the given average bitrate.
To account for this fact in the fake adaptive data set, the chunk size varies
randomly with a given standard deviation. The standard deviation used for the
BandwidthProfileSimulator is based on the chunk size variation measured on the
1 hour playlist of real media.

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.

This change allows applications to provide custom AudioSinks, which could be
based on android.media.AudioTrack like AudioTrackAudioSink, or could be
completely custom.
The refactoring is mostly mechanical and shouldn't result in any functionality
changes.
Some android.media.AudioTrack-specific details have to appear in the AudioSink
interface so this change modifies the javadoc on the AudioTrack (now AudioSink)
to note that some methods will have no effect.
