When skipToData is called the peek position is not equal
to the read position of the input. Hence peeking a chunk
header and then skipping by that amount wont do the right
thing :)!

Mechanical step to create a new HlsSource in the library.
Note that naming is now confusing. This will be fixed in
the next CL, when:

HlsSource -> HlsSampleSource
HlsSampleSource+HlsOutput -> HlsOutput

- This means DrmInitData is propagated through sample queues (i.e.
  is effectively attached to every sample, so we can see when it
  changes when reading from the queue).
- It also allows different DrmInitData per track, which is possible
  in muxed MKV/WebM, and per Representation for DASH, although we
  wont be able to seamlessly adapt in the latter case.

I've seen a sample that has a LIST chunk prior to fmt. It
seems best just to skip all chunks until the format is
located. As per the RIFF spec:

"Programs must expect (and ignore) any unknown chunks
encountered, as with all RIFF forms."

This allows limiting the horizontal extension of the cues.
NOTE: So far, we only support percentages for size magnitudes.

SubtitleParser includes a method updating the current
playback position for parsers that need to be aware
of the position in order to determine how to batch
captions (i.e. Eia608Parser).

- This moves to a single DrmInitData implementation that supports
  both specific and universal UUID matching. You can also do a
  combination of the two, which was not previously possible.
- The object model is simplified as a result. This is a precursor
  to a change where DrmInitData will be included directly in the
  Format to enable key rotation.

In order to apply track type specific policies in
the track selection, we need to know the type of
the track renderer, this method returns one of the
constants defined in C.java of the form TRACK_TYPE_*
to allow renderer classification.

If the media format changes from one Format object to another
one that's is equal (but not the same object), readData would
end up performing an expensive equality evaluation on every
invocation.

This will be required for key rotation to work, since
we'll need a way to determine whether or not the init
data has changed.
