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

This is incomplete for the moment. MesoNH must always be compiled with this key for the time being.

(cherry picked from commit b0bb3125)

Philippe 19/04/2018: IO: add possibility to choose directory for outputs, backups and diachronic files

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

Philippe 22/03/2018: IO: use CFORMAT field of TFILEDATA instead of relying on LIOCDF4, LLFIOUT and LLFIREAD
This prevents some problems when mixing LFI and netCDF files (ie in cdf2lfi)
+ cleaning use of modd_io_ll for LIOCDF4, LLFIOUT and LLFIREAD (and others)

Philippe 15/01/2018: IO: write horizontal dimensions in NC4 files: improvements + problem corrections

Philippe 10/11/2017: IO: replace OPEN_ll/CLOSE_ll by IO_FILE_OPEN/CLOSE_ll for namelist and other files
+ removed some FMLOOK_ll

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

* 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

* added OUTPUTLISTING CTYPE for files (IO_FILE_OPEN_ll and IO_FILE_ADD2LIST)
* added NLU variable in TFILEDATA datatype
* removed HFIPRI argument in IO_FILE_OPEN_ll, FMOPEN_ll, IO_FILE_CLOSE_ll
  and FMCLOS_ll subroutines
* removed FM_ERR subroutine
* KRESP return code is now optional for IO_FILE_OPEN_ll, FMOPEN_ll,
  IO_FILE_CLOSE_ll and FMCLOS_ll subroutines
