Move ds3_convert_file_list's ds3_bulk_object_list initialization code

into a new ds3_init_bullk_object_list function that clients can use in
case ds3_convert_file_list (i.e. _ds3_bulkl_object_from_file) isn't
suitable.  ds3_init_bulk_object_list only allocates the required memory
, for the "list" and the structure itself, and sets "size".
It's up to the user to set list's contents.
