calculate a window duration, which can be awkward.

It's no longer safe to convert END_OF_SOURCE -> duration on
the main therad, since the Timeline from which the duration
is obtained is posted to the main thread, where-as the
buffered position is passed by updating a volatile. Hence
an update to the latter might become visible to the main
thread before the corresponding Timeline.
This change moves the conversion to the playback thread.

- For audio/video, we should report the minimum largest
queued timestamp. This ensures that buffering continues
rather than stops in the case of bad sample interleaving.
- If there are "sparse" tracks then they should be ignored
for this calculation, otherwise the buffered position can
end up getting stuck at some small value (e.g. if there's
a text track containing a single sample with a small
timestamp).
- In the edge case that there are only "sparse" tracks, we
probably want to take the maximum largest queued time
instead.

*** Reason for rollback ***
Referential equality was probably the right thing to do, since using .equals
breaks track selection in the case that a source exposes two or more tracks
whose formats are equal. We should fix the way overrides work instead.
*** Original change description ***
Fix multi-period transitions with track selection overrides
An override applies across periods provided they expose the
same track groups according to .equals, but the formats in
the override are then compared against the period's formats
according to ==. Use .equals consistently to fix.

This change allows MediaPeriod instances to replace
SampleStream instances when the selection isn't changing.
It also allows MediaPeriod instances to retain a
SampleStream but indicate that the renderer consuming
from it needs to be reset.
The change is used to fix the ref'd bug, and is used to
do the same thing in HLS without the need for the source
to report a discontinuity. Note that reporting discontinuity
could cause unnecessary failure when used as a child of
MergingMediaSource.

If a renderer is reading ahead of the playing period, seeking within the
playing period would fail, because renderers would not be disabled but then try
to read from SampleStreams that have a released period.
Also, in the same circumstances, seeking within the reading period would fail,
because all renderers would be disabled, but their sample streams have already
been read. When they are reenabled they expect to see a format but don't
receive one.
In both cases, seeking can just clear the timeline. This only occurs in rare
circumstances when the player is reading ahead, so the cost of re-preparing
will not be incurred often, and allows the seeking logic to be simpler.

Referential equality is going to become important for detecting
whether a SampleStream has been replaced, so we need to create
new instances as we do elsewhere.
This also enables multiple SampleStreams to be provided for a
single TrackGroup, as is also true for DASH and SmoothStreaming.
It's forbidden to ask for multiple SampleStreams from a single
TrackGroup currently, but we may choose to relax that at some
point (and indicate whether it's allowed as a flag on each
TrackGroup).

When seekToPeriodPosition found that the seek destination period was already
prepared, it would not disable/re-enable renderers. This was fine if the
playing period wasn't changing, but in other cases the renderers would be left
reading the incorrect streams (and the underlying periods may have been
released).
Also, transition to the buffering state before re-enabling renderers, so that
the renderers are not started until leaving the buffering state.

For self-initializing segments, DefaultTrackOutput receives

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.

- TrackSelection now exposes the selected formats, ordered
by decreasing bandwidth. This removes the need for DASH,
SS and HLS to do the sorting individually.

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).

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.
