	Added following 2 keys, followedBy and belongsTo, to the response
	of tellStatus.

	followedBy: List of GIDs which are generated by the consequence of
	this download. For example, when aria2 downloaded Metalink file,
	it generates downloads described in it(see *--follow-metalink*
	option). This value is useful to track these auto generated
	downloads. If there is no such downloads, this key will not be
	included in the response.

	belongsTo: GID of a parent download. Some downloads are a part of
	another download.  For example, if a file in Metalink has
	BitTorrent resource, the download of .torrent is a part of that
	file.  If this download has no parent, this key will not be
	included in the response.
