The assertion was so weak it probably wouldn't detect genuine
misuse of the DefaultAllocator API, so it seems fine just to
remove it.

We don't really know what happens when the player is allowed to
continue on the affected devices, but hopefully it either "just
works" or fails in a more graceful way.

Robustness fix to make sure we ignore tags with known names, but
which are nested inside of unknown tags. For example we don't want
to parse the third period in:

<Period>...</Period>
<Period>...</Period>
<CustomTag>
  <Period>...</Period>
</CustomTag>

For decoder reuse, we want disable() to flush the decoder. However,
if the flush needs to release the decoder for some reason, it seems
non-ideal to immediately re-initialize it. Re-initialization can
also throw ExoPlaybackException, which we don't want for disabling.

This change allows a variant of flush that wont re-initialize the
decoder if it has to be released, which will be used from disable().

reloading frmo snapshots. b/117347850. This is a no-op change as the current
default == _fullboot. When we globally flip and make snapshots the default,
these tests would fail and we are moving them over so that when we flip your
tests still pass.

- Always clip to period duration for the last chunk. We previously
  did this only when the last chunk explicitly exceeded the period
  end time. We now also do it when the chunk claims to end at the
  period boundary, but still contains samples that exceed it.
- If pendingResetPositionUs == chunk.startTimeUs == 0 but the
  chunk still contains samples with negative timestamps, we now
  clip them by setting the decode only flag. Previously we only
  clipped such samples if the first chunk explicitly preceeded the
  start of the period.

- It's a no-op for now
- Renderers that want to support retaining resources will move
  some functionality from their disable() implementations into
  reset()
- ExoPlayerImplInternal will be updated to not always call reset()
  immediately after disable(), which is what will enable resources
  to actually be retained.

This makes the following changes to improve consistency among the PlaybackInfo
values:
 1. Update buffered position and total buffered duration after loading period
    is set as both values are affected by a loading period update.
 2. Add copyWithPosition to allow updating the position without resetting the
    loading period.
 3. Forward the total buffered duration to playing position updates
    as it may have changed with the new playing position.

When SubtitlePainter positions the cues centred in the given box, it must add
the left offset of the box to get the correct position.

SubtitleView forwards the cue box position to SubtitlePainter. This should be
the position relative to the canvas of the SubtitleView. Currently, however,
we forward the position relative to the parent of SubtitleView. That causes
problems if SubtitleView has a non-zero offset position to its parent.

A lot of methods just forward to other methods and there is no conceivable
way a player should implement it another way. Moving these methods to a
base player class allows to remove duplicated code across our player
implementations.

For example, using ExoPlayer.STATE_IDLE falls back to the Player.STATE_IDLE
automatically and thus there is no need to keep the deprecated members.
