Makes it possible for the caller to request that a previous callback is
replaced, so we don't end up with more and more callbacks. Also add other
options for future use.
Misc refactoring, e.g. alignment of how modules save tracks and playlists, incl
use of mfi and pli. Also try to avoid direct calls between library and player.
Instead of asking a client to first scan the path into a media_file_info
object and afterwards add it to the queue, we now offer a library
function to directly add a path.
The library-source that can handle the given path translates the path
into new queue item(s) and adds them to the queue.

Library now offers the function "library_exec_async". This allows
library sources to offer functions that will be executed in
the library thread. Useful to allow partial scans of only one source.
"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
