1. Using the Locale on API<21 doesn't make any sense because it's a no-op
   anyway. Slightly restructured the code to avoid that.
2. API<21 often reports languages with non-standard underscores instead of
   dashes. Normalize that too.
3. Some invalid language tags on API>21 get normalized to "und". Use original
   tag in such a case.

AV1 profile recognition requires additional info contained in format.

2-letter codes (ISO 639-1) are the standard Android normalization and thus we
should prefer them to 3-letter codes (although both are technically allowed
according the BCP47).

This helps in two ways:
 1. It simplifies app interaction with our normalized language codes as the
    Locale class makes it easy to convert a 2-letter to a 3-letter code but
    not the other way round.
 2. It better normalizes codes on API<21 where we previously had issues with
    language+country codes (see tests).
 3. It allows us to normalize both ISO 639-2/T and ISO 639-2/B codes to the same
    language.

If we use the default start position, we currently resolve it immediately
even if we need to play an ad first, and later try to project forward again
if we believe that the default start position should be used.

This causes problems if a specific start position is set and the later
projection after the preroll ad shouldn't take place.

The problem is solved by keeping the content position as TIME_UNSET (= default
position) if an ad needs to be played first. The content after the ad can
then be resolved to its current default position if needed.

These methods helps to indicate that a media source isn't used to create new
periods in the immediate term and thus limited resources can be released.

The name of this parameter recently changed in https://github.com/google/ExoPlayer/commit/3fe0b1a6fee8e7631caa5a6f84306396ee6999ad and I forgot
to change these inline comment usages.

It's easy to forget to forward methods when using basic wrapping. For example,
ExtractorMediaSource.addEventListener is currently a no-op because it's not
forwarded.

This is a temporary workaround until we have migrated all MediaSources uses.
This change avoids having to migrate all uses of MediaSources immediately.

- Remove manifest argument from callbacks of Player.EventListener and
  SourceInfoRefreshListener. Instead make it accessible through
  Player.getCurrentManifest() and Timeline.Window.manifest.
- Fix all MediaSource implementation to include the manifest in the
  Timeline instead of passing it to the SourceInfoRefreshListener.
- Refactor ExoPlayerTestRunner, FakeTimeline, FakeMediaSource to
  reflect these changes and make tests pass.

Sending MESSAGE_PREPARE_SOURCE should happen last in the constructor.
It was previously happening before initialization finished (and in
particular before pendingMediaPeriods was instantiated).

We currently use an alpha version which allowed us to access new threading
features. The stable version of this has been released now and we can
switch back.
