Return list of the names of extraneous duplicity files
A duplicity file is considered extraneous if it is
recognizable as a duplicity file, but isn't part of some
complete backup set, or current signature chain.

Returns a list of backup chains older than the given time t
All of the times will be associated with an intact chain.
Furthermore, none of the times will be of a chain which a newer
set may depend on. For instance, if set A is a full set older
than t, and set B is an incremental based on A which is newer
than t, then the time of set A will not be returned.

Return the nth-to-last full backup of the collection,

NOTE: n = 1 -> time of latest available chain (n = 0 is not
a valid input). Thus the second-to-last is obtained with n=2
rather than n=1.
