    Revert "completion redefine gnc:debug" and fix some bugs in it
    
    This change made it impossible to turn debug output on or off on the
    fly by calling qof-log-set-level from Scheme code.  The optimization
    achieved isn't all that great either since the arguements to
    gnc:debug are still evaluated when debugging is off and this is
    where a lot of the overhead is. Even without this change the call to
    strify is avoided.
    
    Also fixed the parameters of qof-log-check:
        "gmc" => "gnc.scm"
        G-LOG-LEVEL-DEBUG => QOF-LOG-DEBUG
    
    This reverts commit b3a4cd62775705b2543438f912ca71dad591bf0e.
