SDK / exoplayer

This issue affects ExtractorMediaSource only. We shouldn't
start loading in the case that we're prepared and have no
enabled tracks, since there's nothing that we need to load.
This was causing an assertion failure in startLoading.

- Fix handling of the currently playing period being
  removed. This didn't do the right thing at all.
- Relax rule on seekToPeriodPosition re-using an
  existing holder.

Note that multi-segment fetching is only possible in the
case that segments in a representation are defined to have
the same Uri and adjacent ranges (this is very rarely true
for live streams, but is quite often true for on-demand).
In the case that merging is requested but not possible,
the implementation will request one at a time.

Also allow custom DashManifestParser injection, to
support parsing of custom elements and attributes that
service providers may wish to include in their manifests
(e.g. #2058).

- Make handleSourceInfoRefreshed clearer.
- Remove bufferAheadPeriodCount. Seems error prone.

This is techically not allowed by the spec[1] but might still occur in
certain scenarios. New playlists with older media sequence numbers are
ignored.

continueLoading shouldn't return true unless it's done
something. Always returning true if endOfStream was
causing CompositeSequenceableLoader.continueLoading to
loop forever.

It looks like the same issue exists in ChunkSampleStream
as well, although I can't seem to provoke DASH or SS
playbacks into doing anything bad as a result.

ReusableBufferedOutputStream is a subclass of BufferedOutputStream with a reset(OutputStream) that allows an instance to be re-used with another underlying output stream.
