"library" thread
- Implement filescanner as a library_source
- Add library source implementation for spotify
- Move process_media_info to library with small adjustments:
- Remove dependency to F_SCAN_TYPE defines
- Pass data_kind as parameter
- Pass media_kind and compilation as parameter if a source forces a
specific value for these
- Move declaration of scan_ffmpeg to library; add
library_add_playlist_info to library
These calls generate error messages when the loop is already running, which
will be the case when using init-rescan or full-rescan. The only purpose
of these calls seems to be to check for exit signals from the main thread
during a startup bulk scan, where the loop is not running yet. However, we
can check for an exit signal by just setting/checking scan_exit.
This commit also removes the unused filescanner_status().
