*** 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.

On an edge case, player may get stuck when the renderers are ready but the buffer doesn't get full enough because of a fatal error in data source. An example state can be created by starting a live DASH stream and switching between normal and slow network connections.

For self-initializing segments, DefaultTrackOutput receives
a null format and then the actual format. This broke the
deduplication logic in InfoQueue.format, since there were
two transitions: FormatX->Null and Null->FormatX. This CL
allows deduplication to succeed in this case.

The codec cannot be reconfigured if the format rotation
changes, or if the format dimensions exceed the current
decoder's configured maximum dimensions.

This wont help much until the buttons to get the dialogs

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.
