Quentin 16/02/2023: bugfix revert 592c5d18 on surf_solar_shadows : the use of XHAT and YHAT is necessary

+ more efficient use of grid variables

Quentin 25/10/2021: bugfix RESTART reproductibility. In the case of no online chemistry (LORILAM=F) or LDUST/LSALT=T processes changing the aerosols (XAER)
at each time-step, XAER is computed once at the START segment in ini_ecmwf_radiations based on current pressure and not updated during MESONH except if LAERO_FT=T and CAER='TEGE'. At RESTART, the aerosols climatology is updated but the
pressure has changed. For reproductibility, one must use LAERO_FT=T and CAER='TEGE'. XAER_CLIM was not updated in the process done by CALL AEROZON in phys_param

TODO: check I/O restart and CALL of write_diachro in write_stationn

Quentin 27/04/2021: NAM_BLANK and DUMMY becomes NAM_BLANK_n for grid_nesting use. The values of the BLANK DUMMY variables can be different in n models. Cleaning of non-used CALL MODD_BLANK

Philippe 07/01/2021: IO: remove GCLOSE_OUT variable/dummy argument (lopened field of tpfile datatype can be used instead)

* change intent of several dummy arguments
* transform several arrays into allocatable
* remove unused dummy arguments

(cherry picked from commit 8a27344b)

(cherry picked from commit 59877f0b)

Philippe 28/03/2018: replace TEMPORAL_DIST by DATETIME_DISTANCE and ADD_FORECAST_TO_DATE and SUBTRACT_TO_DATE by DATETIME_CORRECTDATE

* use new file structure for CLUOUT and CLUOUT0 (->TLUOUT and TLUOUT0)
* use PRINT_MSG with NVERB_FATAL to replace (some) "callabortstop"
* set TFILE_OUTPUTLISTING  to select file for outputs of PRINT_MSG
* removed some unused code
