`DecoderReuseEvaluation` indicates whether it was possible to re-use an
existing decoder instance for the new format, and if not then the
reasons why.
* Video:
* Fix VP9 format capability checks on API level 23 and earlier. The
platform does not correctly report the VP9 level supported by the
decoder in this case, so we estimate it based on the decoder's maximum
supported bitrate.
* Audio:
* Fix handling of audio session IDs
