Quentin 24/01/2019: minor correction on XCEDIS : cancellation of previous modification of XCEDIS with respect to the mixing length

Quentin 23/01/2019: modification of initialization of PM09 convection scheme at hectometric scale.The mass-flux at the surface is reduced and converge to EDKF value when resolution is meso-scale. Flag to turn on : LGZ = TRUE by default. Modifs by Rachel Honnert

Quentin 08/01/2019: correction of the TKE dissipation constant with RM17 mixing length and add RM17 in shallow convection scheme
- ini_cturb.f90 + read_exsegn.f90 : XCED constant is replaced by XCEDIS which depends on BL89 or RM17 mixing length (see Rodier et al. 2017)
- shallow_mf.f90 + all compute_*.f90 : support of RM17 mixing length in shallow convection
- bl89.f90 : add comment

Philippe 03/05/2018: IO: check if NAM_BACKUP namelist is present and that the list of valid backups is not empty

+ use them

* NLFINPRAR in TFILEDATA type is now of KIND=LFI_INT
* use TPFILE as argument instead of its fields for FMOPEN_ll and FMCLOSE_ll

Juan 12/06/2017:read_exsegn.f90, M.Leriche 06/2017 for spawn and prep_real avoid abort if wet dep for aerosol and no cloud scheme defined

(cherry picked from commit 71693a7b)

* added COUT_VAR in the NAM_FMOUT namelist to get the list of the fields to output
* added NFIELDLIST in the TOUTBAK structure to store the list of the fields to output
* added NMNHNAMELGTMAX parameter

+ separate outputs and backups lists

* Find dad file number in SET_GRID (added NOUTDAD variable in TOUTBAK datatype)
* Allocate XBAK_TIME to the right size

* added TOUTBAK datatype to manage the outputs/backups characteristics
* TOUTBAK replace NOUT_TIMES (removed)
* XBAK_TIME is now allocatable

Some files with it are still available as they could be useful later.
