This fixes an issue where quickly detaching and reattaching the player might
cause ads to be requested multiple times with both responses handled.

In order to facilitate enabling a compile-time error check, we are suppressing these existing instances. Once the compile-time error is enabled, we will file bugs to clean up any unfixed instances in [].
Note that this CL should result in no effective changes to the code, but the code as currently-written might contain a real bug. If you'd prefer to fix the bug now, please either reply with edits, or accept this CL then follow up with a change that fixes the underlying issue.
Tested:
tap_presubmit: [] Some tests failed; test failures are believed to be unrelated to this CL

This is a step towards harmonizing the MediaSource Builders and (potentially)
providing MediaSource factories.

- Remove skipping of the VBRI/XING frame before calculating position
offsets. This was incorrect. Instead, a constraint is used to ensure
we don't return positions within these frames, the difference being
that the constraint adjusts only positions that would fall within
the frames, where-as the previous approach shifted positions through
the whole stream.
- Excluded last entry in the VBRI table because it has an invalid
position (the length of the stream).
- Give variables in XingSeeker descriptive names.

The set of active audio processors was only updated on reconfiguration and when
draining playback parameters completed. Draining playback parameters are cleared
in reset(), so if parameters were set while paused then the sink was quickly
reset, without draining completing, the set of active audio processors wouldn't
be updated. This means that a switch to or from speed or pitch = 1 would not be
handled correctly if made while paused and followed by a seek.
Move resetting active audio processors from configure (where if the active audio
processors were reset we'd always initialize a new AudioTrack) to initialize().

- This change snaps the seek position for constant bitrate MP3s
to the nearest frame boundary, avoiding the need to skip one
byte at a time to re-synchronize (this may still happen if the
MP3 does not really have fixed size frames).
- Tweaked both ConstantBitrateSeeker and WavHeader to ensure the
returned positions are valid.

Support ad MediaSources that aren't prepared immediately by using
DeferredMediaPeriod, moved up from DynamicConcatenatingMediaSource.
In a later change the new interfaces will be made public so that apps
can provide their own MediaSource factories.

captions fetcher architecture.
1. ManifestlessCaptionsMetadata
Other captions fetchers must first fetch a manifest (HLS or manifest) to
discover captions tracks. This process does not exist for manifestless. All
we need to do is scan the FormatStream's for the right itag, so this is an
all-static class.
2. ManifestlessSubtitleWindowProvider
Once a captions track is selected, a subtitles provider is instantiated. This
is the main interface used by the player to retrieve captions according to
playback position. This class stores fetched captions in a tree index by time
for efficient lookups. Background captions fetches are used to populate
the tree.
3. ManifestlessCaptionsFetch
Captions are fetched one segment at a time. One instance of this object
is required per fetch. It performs a blocking fetch on call(), and is
intended to be submitted to a background-thread executor.
4. ManifestlessCaptionsFetch.CaptionSegment
This is the result of the caption fetch. These values are used to populate
the captions tree.
Manifestlessness
The initial request is always a headm request. There is a separate tree
of every segment indexed by start time. This tree is used to improve
manifestless sequence number calculation. Once we have data for the current
timestamp, we walk forward through the tree to find the next unfetched
sequence number, and fetch that.

- Avoid re-downloading data prior to the first mdat box when
seeking back to the start of an unseekable FMP4.
- Avoid re-downloading data prior to the first frame for
constant bitrate MP3.
- Update SeekMap.getPosition documentation to allow a non-zero
position for the unseekable case. Note that XingSeeker was
already returning a non-zero position if unseekable.

Also slightly improve language normalization/documentation.
For this CL, it is assumed that null and "und" languages are different
entities. Once we fully tackle language tag normalization, we can decide
whether to normalize the "undefined" language.

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.

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.

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.
