If connecting a Bluetooth audio device fails, the AudioTrack may be left in a
bad state, where it is not actually playing and its position has jumped back to
zero. Detect and work around this case by resetting the track.

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.

MobileHarness allocates random devices for each test and repeats tests up to 5 times to
account for spurious test failures. Some of our tests automatically pass for SDK versions
below a certain threshold. Thus, even if such a version-guarded test would always fail,
the MobileHarness test is likely to succeed as it only needs one random allocation to a
device with a lower SDK version.

To prevent this behaviour and to make sure all tests are actually run, the mobile_test
target is split into multiple targets one for each minimum SDK version.

This is not really useful with the DefaultAudioSink, but could be used in a
custom AudioSink when mixing audio from sources that have different sample
rates.

1. Ignore edit list where the sequence doesn't contain a sync
   sample, rather than failing.
2. Make Mp4Extractor.readAtomPayload so it doesn't try and read
   the same payload twice if a failure occurs parsing it.
3. Make processAtomEnded so that it doesn't pop the moov if
   parsing it fails.

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.

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
public FrameworkMediaCrypto constructors, hence removing this restriction.

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.

Controls are still hidden while playing ads, but if the app pauses the player,
controls will be shown. During ads, the player is not seekable.

When the player enters the background then returns to the foreground, the
content period may not be prepared, so also cache the content window duration.
This means that if the app reenters the foreground while an ad is paused the
time bar can be populated.
