When seeking to the default position in a period, the containing source may
actually return a position in another period. Multi-period live sources can do
this to seek the player to the live edge.
ExoPlayerImplInternal uses the same functionality when the playback position
reaches the end of a period to determine what period/position to play next.
This means that when playback transitions to a multi-period live source from
some other source (playing a concatenation of those two sources), the player
will play the live edge rather than the beginning of the earliest period.

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.

According to the spec, there is no mandatory relation between segments'
sequence numbers of different variants. This CL ignores sequence numbers
when switching variants:
* In vod, the switching playback position is obtained by adding the
duration of previous segments.
* In live playback this is not possible. It is assumed that the
different live media playlists do not drift apart too much, so
the playback position is obtained by subtracting the duration
in reverse order.
In later CLs, the described mechanisms will become the fallback methods
by replacing them with the use of EXT-X-PROGRAM-DATE-TIME information
or more reliable sources.

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.

I think we'll want a "resetPosition" boolean parameter on

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 limitation. A method-reordering-only change will follow

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

SequenceableLoaders, which allows them to be kept in sync
