directory: don't pass fd to traverseAllIn() callbacks

Database traversal should be generic, and not bound to a client
connection.  This is the first step: no file descriptor for the
callback functions forEachSong() and forEachDir().  If a callback
needs the file descriptor, it has to be passed in the void*data
pointer somehow; some callbacks might need a new struct for passing
more than one parameter.  This might look a bit cumbersome right now,
but our goal is to have a clean API.
