Modify sensible heat due to rain sent to the ocean

Modify the sensible heat flux due to rain which is sent to the
ocean. Replace the computation of sens_prec_liq in procedure
calcul_fluxs by a call to sens_heat_rain. Set sens_prec_sol in
procedure calcul_fluxs to 0 because, for now, sens_heat_rain is
supposed to account for both rain and snow.

For the call to sens_heat_rain in procedure calcul_fluxs, we need
an additional dummy argument rhoa of calcul_fluxs. Add dummy
argument rhoa to ocean_cpl_noice, ocean_forced_noice,
ocean_forced_ice and ocean_cpl_ice because we need to pass it down
to calcul_fluxs.

Change the dimension of sens_prec_liq and sens_prec_sol in
procedures calcul_fluxs, ocean_cpl_noice, ocean_cpl_ice,
ocean_forced_noice, ocean_forced_ice, cpl_send_ocean_fields and
cpl_send_seaice_fields to knon.

In procedures ocean_forced_noice and ocean_cpl_noice, promote
sens_prec_liq from local variable to dummy argument because we need
it in surf_ocean. Remove useless initialization of sens_prec_liq
and sens_prec_sol in ocean_cpl_noice, ocean_cpl_ice,
ocean_forced_ice and ocean_forced_noice: they are intent out in
calcul_fluxs.

Remove variable rf of module phys_output_var_mod, we use
sens_prec_liq instead. Remove local variable yrf of procedure
pbl_surface. rf and yrf appeared in pbl_surface only to be output.
Remove variable o_rf of module phys_output_ctrlout_mod. Remove
dummy argument rf of procedure surf_ocean.

Do not call sens_heat_rain in surf_ocean since we now call it
from calcul_fluxs. Move the computation of rhoa in surf_ocean
before the calls to ocean_cpl_noice and ocean_forced_noice.

Add the computation of rhoa in surf_seaice, to pass it down to
ocean_cpl_ice and ocean_forced_ice.

If activate_ocean_skin == 1 then the results are changed because the
call to sens_heat_rain in calcul_fluxs now uses the SST from the
current time step of physics. On this point, the present revision
reverses revision [3463].
