This prevents the workaround from occuring once FFmpeg has the bug
patched.

Also backport the Shield workaround to v1.

- Support querying whether the current window is dynamic
  and seekable. The new methods are similar to getDuration,
  which is also a convenience method for the current window.
- Improve demo app to restore positions in VOD items within
  playlists where the last item is live. Also restore the
  position within the window for live items unless the player
  failed with BehindLiveWindowException.

This class can accommodate extra information that may potentially
be specified by TrackSelectors in the future (e.g. configuration
for renderers). Even if we don't do this, it's cleaner to have a
proper class and an info field to refer to, as opposed to using a
Pair.

Also revert ability to query for a decoder that explicitly
supports tunneling, since in the new design we'll just be
querying the first decoder provided by the MediaCodecSelector
and then reporting what it supports. This is in line with
what we do when reporting support for adaptive switching.

Move initialization code from the audio renderers into handleBuffer. The audio
session id and tunneling enabled state can be altered using new setters.

This change is not intended to change the behavior of the audio renderers.
Before this change, the AudioTrack would always be reinitialized by the
renderers before calling handleBuffer.

Add a protected onAudioTrackUnderrun method for custom renderers that want to
implement custom handling of underruns.

Extra calls to CipherOutputStream.close() causes each time extra 16 bytes written to the
underlying OutputStream. Prevented close() is called more than once and also discarded any
data in ReusableBufferedOutputStream buffer on reset().

ClippingMediaPeriod may be a useful component for other MediaSources too so
remove its dependency on ClippingMediaSource.

Also allow the clipping end point to be TIME_END_OF_SOURCE, in which case
the clipping window extends to the end of the wrapped period.

This is analogous to what we do for text/subtitles, and
adds support for playlists where the type of metadata
changes from one playlist item to the next.

We've seen this issue reported three times now, so it's
obviously not an isolated problem. Do you think anything
bad will happen to non-SmoothStreaming playback cases if
I do this? I suspect not, but if you feel strongly I can
easily add a FLAG_WORKAROUND_X flag for it, and enable
it for SmoothStreaming only.
