Useful functionality promoted to core library:
1. Management of SurfaceHolder.Callback lifecycle
promoted to SimpleExoPlayer
2. Ability to determine whether audio/video tracks
exist but are all unsupported promoted to
MappingTrackSelector.TrackInfo
3. Read external storage permissions check promoted
to Util
4. SubtitleView given ability to act directly as a
TextRenderer.Output to remove layer of indirection
5. SubtitleView given ability to configure itself to
user's platform wide caption styling
6. KeyCompatibleMediaController promoted to library's
UI package.
Relocation of boring stuff:
1. ID3 frame logging moved to EventLogger.

This change merges the duties of FormatEvaluator into
TrackSelection classes, so that both the static and
dynamic parts of track selection are implemented in a
single place.
New feature: Demo app now allows you to enable random
adaptation in the track selection dialog.
Notes:
- It should be quite easy to allow application side
track blacklisting in addition to source side, as an
extension to this. That would effectively allow
applications to do seamless/deferred track selection
by creating a TrackSelection with all tracks enabled,
and then toggling the blacklist flags to select the
ones they want to be active.
- It should be trivial to implement format blacklisting
for DASH and SS as an extension to this. Will do in a
follow up CL.

It's only "needed" for HLS, and this requirement will
go away soon. It's safe to remove the flag ahead of
this because a TrackSelector can/should not attempt to
adapt between multiple audio/text tracks.
Also remove unnecessary restrictions on TrackGroups
being non-empty and only of known types.

- TrackSelection now exposes the selected formats, ordered
by decreasing bandwidth. This removes the need for DASH,
SS and HLS to do the sorting individually.
- The change also removes the need to reconstruct TrackSelection
instances with a different group index in various places
(e.g. MergingMediaPeriod).
- This is also a step toward potentially packaging the
FormatEvaluator inside of the TrackSelection (TBD).

SmoothStreaming -> Ss
MediaPresentationDescription -> DashManifest

Moved DASH and Ss manifest classes to matching
manifest packages for consistency. For Hls the
package is called playlist still, since that's
what they're widely known as.

This also removes direct use of HttpURLConnection and
allows use of any HttpDataSource for license requests,
which means those using OkHttp can finally use the
same network stack for license requests as they're using
for everything else, without having to implement their
own callback.

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.

This change restores ExoPlayer to its previous behaviour.
I think we'll want a "resetPosition" boolean parameter on
setMediaSource at some point, but no need to add it right
now. Note that this would not always reset to the start
of the source. For a live playback it will reset to the
desired position (normally somewhere slightly behind the
live edge).

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.

The BandwidthMeter should only be used by MediaSource
instances and the objects they reference, so there's
really no reason for the player to need to know about it.
This change sacrifices DebugTextViewHelper showing the
estimated bandwidth, but I think that's a price worth
paying.

It doesn't look like TrackSelectionPolicy is going to be
useful other than with DefaultTrackSelector, and it's kinda
confusing dealing with both "selector" and "policy"
terminology. This change does the following:
DefaultTrackSelector -> selector.MappingTrackSelector
DefaultTrackSelectionPolicy -> selector.DefaultTrackSelector
TrackSelectionPolicy -> [deleted]

There aren't really enough classes to justify it right
now, but if we're going to do a VideoView equivalent and
sensible player controls at some point, it's worth making
now to get classes into the correct place.

app wish to include both v1 and v2 for a period of time. This is
similar to the approach used by some other open source projects
(e.g. okhttp).

At a high level, everything that we need to load in sync
with anything else now implements a new SequenceableLoader
class. This includes ChunkTrackStream, since multiple
demuxed tracks in DASH/SS need to be loaded in sync with
one another. At a higher level, SampleSources are also
SequenceableLoaders, which allows them to be kept in sync
by MultiSampleSource.
CompositeSequenceableLoader is able to load multiple
instances SequenceableLoaders in sync with one another,
and is used in various places where this is required.
This change also removes LoadControl registration, which
was complicated and error prone.

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).

- 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.

If the same instance is reset then rapidly re-enabling the
renderer after disabling it can prevent an application from
reading the final values at the time when the renderer was
disabled. Hence we now instantiate a new CodecCounters each
time. This is needed to migrate DashTest to V2.

The allocator and buffering policy (e.g. how large the buffer
is) is moving to the top level as part of playlist support,
so it no longer makes sense to inject these parameters as
args into ExtractorSampleSource's constructor.
Instantiating the allocator and buffer size inside of the
source is temporary and only until they're moved up.
