Surface Module : need for wind speed in 'new' tke and CFCs (for instance)

Description

When phasing the DRAKKAR 'new' TKE (??) with the trunk, I found that the windspeed is needed for
the Lang Muir cell stuff. On the other hand, for passive tracers, and in particular CFC or BombC14, the wind speed is also required for computing the exchange coefficient.
I have seen that in TOP/CFC/trcsms_cfc.F90, this wind speed is re-computed from the
wind stress via a constant drag coefficient.
Won't it be easier to work directly from the wind speed which is available when working with bulk such as core ? In this case, there should be somewhere a PUBLIC variable for
the windspeed. Do you agree ?

OK we agree. Christian is currently preparing a update in that direction: module provided by bulk, or computed from the stress when flux or analytical formulation is used. And the in both new TKE and TOP, use the module sbc_oce containing this module.
