Changeset 2738

Small modifications for TAF :

• hydrolc_waterbal : removed argument first_call never used.
• hydrolc_alma : extracted the initialization part into hydrolc_alma_init
• stomate_season.f90 : cloud becomes a local temporary variable. Note that this variable is never calculated, it is only set =0.
• forcing_read in module stomate is renamed into stomate_forcing_read
• routing_waterbal : rename firstcall into reinit. Variables with name firstcall must be global with attribute SAVE.
• Changed name on the variable firstcall into firstcall_xx to have unique name in each module. Done in following subroutines : stomate_vmax, stomate_turnover, stomate_soilcarbon, stomate_season, stomate_resp, stomate_prescribe, stomate_phenology, stomate_npp, stomate_litter, stomate_io, stomate_alloc, lpj_pftinout, lpj_light, lpj_gap, lpj_fire, lpj_establish, lpj_constraints, hydrolc, solar, weather
