When creating PlaybackControlView inside SimpleExoPlayerView,
we want certain attributes to be passed through. This lets you
set control attributes on the SimpleExoPlayerView directly. We
don't want all attributes to be propagated though; only our own
custom ones.

Not sure if there's a cleaner way to do this. Pragmatically this
solution seems ... ok :)?

This appears to be fixed in Oreo, but given how harmless
the workaround is we can probably just apply it on all
API levels to be sure.

Reporting incorrect positions for ad playbacks was causing IMA to
think the ad wasn't playing, when in fact it was.

We currently switch without downloading overlapping segments, but
we do not actually switch more aggressively. This change fixes
this. Note there's an implicit assumption made that if one media
playlist declares independent segments, the others will too. This
is almost certainly true in practice, and if it's not the penalty
isn't too bad (the player may try and switch to a higher quality
variant one segment's worth of buffer too soon).

The bytesRemaining didn't always take into account any skipped bytes, which
meant that reaching the end of the file was not correctly detected in read().

UTF-8 is the default charset on Android so this should be a no-op change, but
makes the code portable (in case it runs on another platform).

Make getMediaFormat protected so that subclasses can set additional MediaFormat
keys. For example, if the decoder output needs to be read back via an
ImageReader as YUV data it is necessary to set KEY_COLOR_FORMAT to
COLOR_FormatYUV420Flexible.

- This is soon becoming mandatory.
- It also looks like future versions of com.android.tools.build
  are being distributed via Google's Maven repository.

These methods are only used in one place, and offer duplicate
functionality to checking getNext(Previous)WindowIndex == C.INDEX_UNSET.
