    [commodity-utilities] create internal fn to bypass expensive call
    
    This commit creates an internal
    function (gnc:get-commodity-totalavg-prices-internal) which bypasses
    a call to (gnc:get-match-commodity-splits-sorted) which creates a
    query for the price-commodity.

    [commodity-utilities] compact functions
    
    and convert (gnc-numeric-*) to scheme number functions

    [commodity-utilities] optimize weighted-average price calculator
    
    (get-commoditylist-totalavg-prices) will generate a whole-book
    splitlist. This is then filtered to 'interesting' splits only, and
    sorted by posted date.
    
    This sorted, filtered list is then filtered to each commodity, and
    passed down as argument to (gnc:get-commodity-totalavg-prices) to be
    used immediately, rather than calling the expensive function
    (gnc:get-match-commodity-splits-sorted) which eventually creates a
    query for each commodity.
