    Don't use GNC-DENOM-SIGFIGS when converting prices
    to gnc-numeric values.

    Revert the part of 923b01e2 which reverses currency quotes less than 1.
    Now that GnuCash uses 64 bit numbers in numerics this is not necessary.
    It can store a number as small as 1e-9 with 9 significant digits.

    Fix the comments on double_to_gnc_numeric.  GNC_DENOM_AUTO is allowed.

    Make test-backend-dbi-basic build and run with libdbi 8.
    
    This may not be the correct fix, but it is plausible and it
    makes the test build and run.
