The State_Chm%HetInfo and State_Diag%SpeciesBC fields were never set
to NULL during initialization.  While this is OK for most simulations,
when doing a dry-run simulation, this will cause deallocation to fail,
at least when using GNU Fortran.  This would cause a segmentation fault
at the end of dry-run simulations (but the dry-run simulations would
finish otherwise OK).

File reads have been moved out of the INIT_UCX routine, but there were
still some print statements left over.  These print statements would
write that a non-existent file was missing, thus causing dry-runs to
fail.  We have now removed these extraneous print statements.

Here we are stashing some modifications to download_data.py for
downloading restart files for GEOS-Chem 13.0.0.

Will need to work on this further...

The NOON_FILE_ROOT variable was a module variable that was removed in
the prior commit 991ca72.  However, this variable is needed to read
in the UCX boundary conditions in routine NOXCOEFF_INIT.

We have now restored NOON_FILE_ROOT as a local variable to NOXCOEFF_INIT.

(1) run/GCClassic/createRunDir.sh:
 - Aerosol simulations now use the fullchem restart file
 - POPs simulation now looks for an initial restart file w/ the extra
   option (BaP, PYR, PHE) in ExtData/GEOSCHEM_RESTARTS/v2020-02
 - All other specialty simulations use restart files in
   GEOSCHEM_RESTARTS/v2020-02 on the remote server
 - Send error output from aws s3 cp to dev/null

(2) run/shared/download_data.py
 - Look for NK15 and NK40 in input.geos to decide if we are
   need to download data files for TOMAS15 and TOMAS40 simulations
 - Use the fullchem restart file (Jan 2019) for the aerosol simulation
 - Look for specialty simulation restart files in GEOSCHEM_RESTARTS/v2020-02
 - When downloading data from ComputeCanada, first download it to
   the local GEOSCHEM_RESTARTS directory tree, then copy it to the
   run directory.
 - AWS restart files should now be placed in the run directory by
   createRunDir.sh.  But if a restart file is missing, running
   download_data.py with -aws will restore it.

NOTE: There may still be an issue with the POPs restart files on AWS,
but since POPs is not used by many people I am not sure if we want
to end up fixing this.
