Message:

1) Reactivated ability to read ozone (that was deactivated because of
dependency on version of IOIPSL). Added ability to read a pressure
coordinate in Pa in "regr_lat_time_climoz".

2) Added the ability to read a second ozone climatology, corresponding to
daylight ozone:

-- "read_climoz" is now an integer variable, instead of a logical
variable.

-- Added argument "read_climoz" to "phys_state_var_init",
"phys_output_open" and "regr_lat_time_climoz".

-- Created new variable "ozone_daylight" for "hist*.nc" output files.

-- Added a third dimension to variable "wo" in module
"phys_state_var_mod" and variable "POZON" in "radlwsw": index 1 for
average day-night ozone, index 2 for daylight ozone.

-- Added a fourth dimension to variables "o3_in", "o3_regr_lat" and
"o3_out" in "regr_lat_time_climoz": index 1 for average day-night
ozone, index 2 for daylight ozone.

-- In "physiq", moved call to "conf_phys" before call to
"phys_state_var_init". Thus, "conf_phys" is now inside the block "if
(first)" instead of "IF (debut)". There were definitions of "bl95_b0"
and "bl95_b1" that were useless because the variables were overwritten
by "conf_phys". Removed those definitions.

-- In "radlwsw", we pass the average day-night ozone to "LW_LMDAR4"
and the daylight ozone, if we have it, to "SW_LMDAR4" or
"SW_AEROAR4". If we do not have a specific field for daylight ozone
then "SW_LMDAR4" or "SW_AEROAR4" just get the average day-night ozone.

-- "regr_lat_time_climoz" now manages latitudes where the input ozone
field is missing at all levels (polar night).

-- Encapsulated "radlwsw" in a module.

3) Modifications to make sequential and parallel versions of
"create_etat0_limit" almost identical:

-- In "dyn3dpar/create_etat0_limit.F". No need to call
"phys_state_var_init", removed "use phys_state_var_mod" statement. No
need for "clesphys.h", removed "include" statement.

-- In "dyn3dpar/etat0_netcdf.F". Added argument "tau_ratqs" in call to
"conf_phys" (this bug was already corrected in "dyn3d"). Moved call to
"inifilr" after call to "infotrac_init" (as in "dyn3d").

4) Other peripheral modifications:

-- Added procedures "nf95_get_att" and "nf95_def_var_scalar" in
NetCDF95 interface. Overloaded "nf95_put_var" with three more
procedures: "nf95_put_var_FourByteReal", "nf95_put_var_FourByteInt",
"nf95_put_var_1D_FourByteInt".

-- Overloaded "regr1_step_av" with one more procedure:
"regr14_step_av". Overloaded "regr3_lint" with one more procedure:
"regr34_lint".

-- Corrected call to "Init_Phys_lmdz" in "dyn3d/create_etat0_limit.F":
the last argument should be an array, not a scalar.

-- Encapsulated "conf_phys" in a module.

-- Splitted module "regr_pr" into "regr_pr_av_m" and "regr_pr_int_m".

5) Tests:

This revision was compared to revision 1259, with optimization options
"debug" and "dev", parallelization options "none", "mpi", "omp" and
"mpi_omp", 1 and 2 MPI processes, 1 and 2 OpenMP threads, with the
compiler "FORTRAN90/SX Version 2.0 for SX-8". Both programs
"create_etat0_limit" and "gcm" were tested. In all cases,
parallelization does not change the results. With "read_climoz = 0" in
the ".def" files, the results of revision 1259 and of this revision
are the same.
