    Bug 797584 - New-owner - bill amount field links to wrong account
    
    Amounts formerly linked to the 'transfer' split which is not reliably
    determined. Link to the APAR split instead.
    
    Note whereby a payment spans multiple invoices, it'll link to the
    first APAR payment split.

    [new-aging] speed up by skipping several loops
    
    Consider a list of APAR splits, from N accounts. For each account,
    their splits needed to find unique valid owners.
    
    Previous algorithm would loops splits several times (1) each split
    finds its owner, and log invalid ones, and (2) delete owner
    duplicates.
    
    New algorithm will take the first split's owner, skip if invalid, then
    process all owner-splits, the reloop with other-owners-splits. The
    invalid-splits list is also managed within loops for better stack
    handling.
    
    Also use (ice-9 match) for conciseness.

    [new-aging] replace split->lot->split->lot with split->lot
    
    remove unnecessary call to get earliest-split
