* Some correction on parallelization : [[BR]]
   In all files, we change all "index" variables because of index fortran keyword.[[BR]]
   ioipsl_para	    : respect getincom INTENT specification [[BR]]
   transfert_para   : suppress the test that has forbid the use of only one processus with the parallel compilation. [[BR]]
   routing : routing was called with a test of local number of points. Then routing wasn't everywhere and it broke parallel communications. Sometimes on one processor, there should be only one land point.

 * hydrolc : Change check_waterbal to .FALSE. [[BR]]
   * Explicite initialization to zero of variables : [[BR]]
     bqsb, gqsb, dsg, dsp, mean_bqsb, mean_gqsb, dss, precisol, gdrainage, subsnowveg, subsnownobio,
     snowmelt, icemelt, mx_eau_var, ruu_ch, vegtot, resdist and runoff [[BR]]
   * hydrolc_snow : Suppression of a lot of messages [[BR]] 
     " ATTENTION on prend de l eau au sol nu car evapsno est trop fort!" [[BR]]
     They are replaced by only one message.
   * hydrolc_soil : Correction (Yann Meurdesoif) of lbad algorithm to compute vertical diffusion.

 * slowproc : Change getin Key (and variable)  VEGET_LENGTH for VEGET_UPDATE
