* Fix of the issue that seeking in large MP3
file would cause OOM error when creating
MP3 indexes. This caused OS crash when
looping large MP3 file in Relaxation.
* Minor cleanups.
* Fix of the issue that 'File has been
deleted' popup would show in Relaxation
app at the end of playback if the
playback was paused at least once,
even though the file wasn't actually
deleted.
* Added very basic audio decoder error
handling and propagation mechanism.
* Minor refactor around several
audio-related parts.
