#1791: add namelist parameter nn_vvl_interp to control how scale factors are set at U-V-F points. nn_vvl_interp=0 is the old interpolation scheme that do not account for steps. nn_vvl_interp=1, corrects the bottom thicknesses, but does not ensure that they get too small for stability. nn_vvl_interp=2 is a "qco like" formulation, for which scale factors anomalies are set proportional to the scale factors at rest. Set nn_vvl_interp=2 as the default.
