    [engine.i] even faster gnc_get_match_commodity_splits
    
    gnc_get_match_commodity_splits needs to scan the account splitlists to
    find suitable splits upto end_date. Because splitlist is date-sorted,
    use gnc_account_foreach_split_until_date to avoid scanning later
    splits.

    [account.cpp] add gnc_account_foreach_until_date
    
    - uses binary search to find first split after date
    - for_each from earliest split to (but excluding) the above first split
