Creating a period in MaskingMediaSource may result in delayed event reporting
depending on when the actual period gets created. To avoid event reporting
inaccuracies, report the mediaPeriodCreated and mediaPeriodReleased events
directly.

Both tags allow any BCP47 compliant code, not just the ISO 639-2/T ones.

This changes the logic in the following ways:
 - If no preferred language is matched, prefer better scores for the selected
   audio language.
 - If a preferred language is matched, always prefer the better match
   irrespective of default or forced flags.
 - If a preferred language score and the isForced flag is the same, prefer
   tracks with a better selected audio language match.

Some variables were defined although they are the default and other things
were set-up in a non-sensible way, e.g. asserting that audio is selected
although no audio renderer is available, or using unset duration for
everything.

PlaybackInfo changes are one of the last ones not masked and reported in the same
way as all other changes.

The main change to support this is to also mask the parameters set in
DefaultAudioSink.

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.

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.

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.
