- 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.

- Only setup a codec to allow adaptation to other compatible
  formats in the stream. If something like the mimeType is
  changing adaptation will never be possible, so there's no
  point.
- Incorporate maxInputSize into the reconfiguration logic.
