This is required for buffering to work properly across
playlist transitions. It's also much simpler, since
specifying the buffering policy becomes independent of
the type of media being played (i.e. the source).

1. The readiness of the timeline is only relevant if there
   aren't any enabled renderers. It's also only ready if
   the source after the playing source is actually prepared
   (if not, we're waiting for preparation).
2. Prevent early transition to the ENDED state when the
   playback position hits the duration, but we're not at the
   final entry in the playlist.

- Always continue loading if we've got less than the minimum
  amount of media in the buffer.
- Use LoadControl in ExtractorSampleSource.

- Update playbackInfo duration/position/bufferedPosition in a
  single place.
- Remove sampleSource variable, and remove side effects from
  getSampleSource. There was actually a subtle bug where
  getSampleSource wasn't called by anything where no renderers
  where enabled (meaning the source never transitioned).

are selected.

Also do some naming cleanup + do ms->us seek conversion
in ExoPlayerImpl, since that's where we now do all the
conversions coming out of the player.

This CL only provides checks for HEVC codecs and adds codec information to Format
instances in DASH. Right now, we check that the supported profiles are advertised
individually and that the supported level is equal or higher than the requested codec
level.

We have our snazzy new file-based extractor tests now,
and the other ones have historically proven way more
hassle than they're worth (e.g. I spent a good few hours
once just trying to work out how to fix the Mp4 extractor
test, having established it was the test and not the
code that was broken!).

I think some more can go from the ogg package, but leaving
in place for now because it's a bit less clear what to
get rid of.

- AllowedVideoJoiningTimeMs must be set to 0 for tests so
  that tests which disable/enable video renderers don't
  register a large number of dropped frames.
- Fixed a threading issue that could cause occassional test
  failure.

The ones that are commented out are legitimately broken
and will need a library fix.

It looks like the manifests are essentially pointless,
but various tools are unhappy if I delete them.

When buffering playlist items after the currently-playing one,
continueBuffering should take a position that is negative because the playback
position is before the start of the source being buffered. This change makes
sure that ExtractorSampleSources always have a known duration when they are
fully buffered, which means that the correct (negative) source-relative
position can be calculated.

ExtractorSampleSource covers almost all use cases (except for AMR, AVI and
legacy Widevine). The FLAC extension must be compiled for support for FLAC
extraction.

FrameworkSampleSource has device-specific issues, makes blocking calls to the
underlying MediaExtractor, and does not provide much control over buffering.

- Event listener is now at the SampleSource level, since the
  individual ChunkTrackStream instances are created internally.
- Event listener receives events corresponding to loads made
  at the SampleSource level (e.g. manifest fetches) in addition
  to those made by the ChunkTrackStream instances.
- Added ability for FormatEvaluators to propagate arbitrary
  information (as an Object) through to the listeners. This was
  a request from YouTube.
- Added significantly more information to each event, for example
  the DataSpec that defines the load being made is now passed, as
  is timing information.

DashTest will be migrated separately, since it's a little
more work.
