Philippe 22/01/2019: replace double precision declarations by real(kind(0.0d0)) (to allow compilation by NAG compiler)

Philippe 21/01/2019: add LIO_ALLOW_NO_BACKUP and LIO_NO_WRITE to modd_io_ll to allow to disable writes (for bench purposes)

Quentin 17/01/2019: cleaning : remove of cyclic conditions-like on DP and ZA variables (useless here)

Philippe 11/01/2019: NVERB_INFO->NVERB_WARNING for zero-size fields + ignore them for LFI files (already done for nc4)

+ some corrections in the error messages

+ move IOFREEFLU and IONEWFLU to mode_io_file_lfi.f90
+ move management of NNCID and NLFIFLU to the nc4 and lfi subroutines

Quentin 10/01/2019: add a local filtering for very high slopes in PGD step (for a better chance of pressure solver convergence). In namelist NAM_ZSFILTER : possibility to activate or not (LHSLOP), choose the number of filtering iterations (NLOCZSFILTER) and the slope value (XHSLOP= Dz/Dx and Dz/Dy) where the filter is applied

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 14/12/2018: restructuration of LFI calls in several modules + other changes and improvements

Philippe 13/12/2018: split mode_netcdf module into multiple modules + add new subroutines to check if a file has been closed correctly
This is done:
*to reduce circular dependencies problems
*to have cleaner code
*to compile faster
*to detect problems with not correctly closed netCDF files

Juan 10/12/2018 : // Correction , mpi_bcast CG & CG_POS parameter & initialize INBLIGHT on all proc for filling/saving AREA* arrays

Philippe 05/12/2018: cdf2cdf: better support for older files (<5.4.0) and special treatment for EMIS
