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 23/03/2021: budgets: CBULIST_* are now allocatable and are compacted at the end of the budget initialization

+ use them

* 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

* this is the beginning of the implementation of separated outputs and backups
* also, improved things by removing duplicated values and sorting them
