This is implemented in the same way as in MediaCodecRenderer.
Move codec != null guard into feedInputBuffer to handle the case of an input
format change with no dequeued buffers where the codec can't be reinitialized
immediately.

I can't see how this would ever make a difference, but there's no
point in returning true. Either we've really reached EOS (in which
case outputStreamEnded will be true and the next drainOutputBuffer
will be turned into a no-op) or we've re-initialized the codec (in
which case there wont be anything to drain since we wont have fed
anything to the codec yet).
This change should also prevent the hypothetical NPE described in
issue #2096, although we're unsure how that NPE would occur unless
MediaCodecRenderer has been extended in an unusual way.

Also inline a few methods/classes where they can be made
private and therefore be removed from the public API.

- Use a single constant for unset/unknown times across
all time bases. Note also that this moves away from
use of -1 for unset/unknown times in ms, which was a
bad choice (it might conflict with real times, such
as a time representing being just behind the start
of a live window).
- Add a few other unset constants, and use them.
- Fix some hardcoding of -1 where existing constants
should have been used.

- Remove null checks (never happens).
- Use "const".equals(Util.CONST) where possible.

With this change, MediaCodecRenderer acquires a session
from its DrmSessionManager whenever the DrmInitData in
the format changes. The DrmSessionManager is permitted
to return the same session if it can be re-used.
This plumbing adds support for:
1. Key-rotation, in the case that a key-rotation-aware
DrmSessionManager is used. Such an implementation will
return the same DrmSession for every aquisition, but
will be making use of multiple MediaDrm instances within
that session to enable the rotation.
2. Playlists with mixed clear and protected content. One
final piece to this will be to have each MediaPeriod
provide its own license URL. We could also allow each
MediaPeriod to specify the DRM UUID, but switching from
PlayReady to Widevine in a playlist seems like quite a
hypothetical thing.

In V1 we received complaints that Renderer was too locked down.
In particular, it wasn't possible to implement a Renderer that
wrapped another Renderer, since most of the methods were package
private and final (e.g. enable).
This change defines Renderer as a proper interface, removing
this limitation. A method-reordering-only change will follow
this one, to get things into a nice consistent/sane order in
each of the Renderer classes.

1. Rename "extensions" package to "decoder". It's used by both
text and (should be used by) metadata, so it's no longer just
for extensions.
2. Move Buffer objects move into the decoder package.
3. Rename SubtitleParser and MetadataParser to SubtitleDecoder
and MetadataDecoder respectively, since they extend Decoder.
Ditto for all subclasses.
4. Subtitle and Metadata decoders now throw their own exception
types rather than ParserException.
5. Move MediaCodec classes into a mediacodec package, with the
exception of the concrete audio and video renderers.
6. Create an audio package to hold the two audio renderer classes
plus related util classes.
7. Create a video package to hold the one video renderer class
plus related util classes.
After this change the following nice properties hold:
1. Want a video renderer? Look in the video package. Ditto for
audio, text and metadata.
2. All TrackRenderer implementations use a decoder of some kind
to decode buffers received from the source, so we have
consistent terminology there.
