Occasionally the player could transition from playing content to playing an ad
after IMA called playAd. The discontinuity triggered faking the content
position, and the fake position was passed to IMA when content resumed causing
the wrong ad group to be loaded. Fix this by only faking the position if the
player transitions before playAd.
Also fix the calculation of the expected ad group index for a postroll ad, and
wait for the player to transition back from ad to content before passing a
content progress update.

If an exception is thrown in an IMA callback it crashes the process with lots of
logging from WebView (including several stack traces, etc.). This change wraps
ImaAdsLoader code that might throw, skips any remaining ads (as the errors are
not recoverable, in general) and notifies a new load error callback so that the
application can implement its own handling. The intention is to make the loader
robust to unexpected requests from IMA and avoid crashes.
Also handle IMA loading an ad in an ad group that has no available ads. In rare
cases IMA will try to load an ad for which an error was previously notified, so
this drops those load requests allowing playback of the content to continue.

All media periods are part of a queue of windows buffered and played by
ExoPlayer. When repeating windows, the current MediaPeriodId is insufficient
to distinguish between the repetitions of the same period. This makes it hard
to see to which media period load events belong to, and it is also difficult to
determine whether two media periods belong to the same logical window or
whether they are part of different repetitions of the same window.
Therefore this change adds a unique sequence number to each window in the
sequence of windows and this sequence number is saved as part of the
MediaPeriodId.

If there was no preroll and the pending content position was set before the
first midroll, the pending content position was never cleared so loading the ad
was never triggered.
Only set a pending content position if we know that we need to trigger playing
an ad for the current position and IMA will poll for an ad (because there is a
midroll ad group). Clearing the pending content position happens when IMA pauses
content to play the ad.

IMA sometimes delivers an ad group load error just after the time of the ad
group, which is problematic now that we set the expected ad group index based on
the last returned content progress.
Only update the expected ad group index once we are within a fixed preloading
threshold of the next ad.
Also fix updating the ad group to use the new ad count, and check for ad group
load errors when we have no expected ad group defensively.

Content progress is only polled if there are midroll ad groups. If the ad tag
had only preroll/postroll ads, the pending content position was not provided to
IMA, which meant that the postroll ad could never play.
Only set the pending content position if there are midroll ads.

Also make ad group skipping more robust. After calling onError for an ad, IMA
will sometimes trigger an ad group load error, so this needs to be handled in a
way that allows some ads to be loaded already for the ad group.
This change also fixes calculation of the expected ad index to take into account
whether the position is being faked to trigger loading an ad or is the actual
player position.

Releasing the player released the internal playback thread once renderers were
released. Releasing a MediaPeriod queued a Loader.ReleaseTask on the loading
thread which would post back to the playback thread. If the playback thread had
been quit by the time this happened, the release task wouldn't be run.
Release on the loading thread instead of the playback thread. This avoids
needing to block releasing the player until the loading threads have ended, and
ensures that release tasks will run eventually. As part of this change,
ExtractorMediaPeriod's call to Extractor.release will now run on the loading
thread (which means that all Extractor methods are called on that thread) and
other cleanup in ReleaseCallback will run on the loading thread instead of the
playback thread.

IMA's cue points may not be in order, so sort them. It looks like IMA events use
time ordered ad indices, so it is not necessary to map between the original cue
point order and the time order.

There are 4 tests which can't currently be moved:
- DownloadManagerTest explicitly uses the main looper which isn't easily
supported because the test runs on this thread.
- ContentDataSourceTest uses an AssetFileDescriptor which wraps a
ParcelFileDescriptor. It seems Robolectric doesn't correctly forward the
inner wrapped file descriptor leading to NPE.
- CacheContentIndexTest and SimpleCacheSpanTest both work fine with Gradle
but fail with seemingly valid test failures on Blaze.

Allow skipping an ad group when requested by IMA, even if we aren't currently
playing one, to handle cases where no ads in an ad group will load (so IMA
requests resuming content but we never managed to start playing an ad).
Use the known ad group index (rather than the expected one) when handling ad
group load errors. This ensures we skip the right ad group if we notify IMA of
playback errors for every ad in the ad group, then IMA notifies that the ad
group is empty via a load error.
Also make some other miscellaneous small fixes to ads code:
- Avoid warning about unexpected ad group indices more than once.
- Output a warning if the ad count in an ad group decreases.
- Remove unnecessary assertion.
- Fix getting the ad duration for ad indices that haven't loaded yet.
- Allow setting an ad group state to its current value.
- Fix javadoc for setting the ad resume position.

This could happen when a media source is removed from a
DynamicConcatenatingMediaSource and one of its media periods is still active.
This media period is only removed by the player after the player received
a timeline update and thus we shouldn't release the removed child source
as long as it has active media periods.

DefaultExtractorInput.SCRATCH_SPACE buffer is used to skip data by
reading it into this buffer and discarding.
Simultaneous use of skip methods corrupts this buffer. Normally the
read data is discarded so it doesn't matter but the underlying
DataSource may use the buffer too. If it's a CacheDataSource it uses
this buffer to read data from upstream then write to cache.
