Added the new runtime parameters MIN_DZ_FOR_SLOPE_N2 to specify a previously hard-coded dimensional parameter in the MOM_lateral_mixing_coeffs module. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for configurations using the some forms of the Eady growth rate slope calculation.
Added the new runtime parameters EN_CHECK_TOLERANCE to specify a previously hard-coded dimensional tolerance in the MOM_internal_tides module. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for configurations using the MOM_internal_tides module.
Added the runtime parameters MEKE_LSCALE_MAX_VAL and MEKE_MIN_DEPTH_TOT to specify two previously hard-coded dimensional parameters that are used with some options of the MEKE parameterizations. Also added or amended comments annotating the units of some of the internal variables in the MEKE module. By default, all answers are bitwise identical, but there are new entries in the MOM_parameter_doc.all files for some configurations using the MEKE parameterization.
Added the runtime parameter MEKE_MIN_DEPTH_DIFF to specify a previously hard-coded dimensional parameter that is used to constrain the averaging of the horizontal diffusivity used with the MEKE parameterizations. By default, all answers are bitwise identical, but there is a new entries in the MOM_parameter_doc.all files for some configurations.
Introduced a fatal error when diagnoseMLDbyDensityDifference is directed to calculate the mean stratification in a region below the mixed layer but dz_subML is not provided as the depth extent over which to average the stratification, replacing the previous hard coded (but unused) default value of 50 m. Also replaced a hard coded floor on the minimum thickness over which to apply boundary fluxes of 1e-30 m in applyBoundaryFluxesInOut with GV%H_subroundoff, which is also a tiny value. This floor is here just to avoid division by 0; while it is possible for this to change answers in some cases where ANGSTROM=0, even then there are other limiters that should apply so the solutions should not change. All answers are bitwise identical with for the MOM6-examples test suite, and very likely for all existing MOM6 configurations.
Added the new runtime parameter KD_SEED_KAPPA_SHEAR to specify a previously hard-coded dimensional parameter used in the MOM_kappa_shear module. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for configurations with USE_JACKSON_PARAM = True.
Added the new runtime parameter ENTRAIN_DIFFUSIVE_MAX_ENT to specify a previously hard-coded upper limit on the rate of entrainment in the buffer layers with a bulk mixed layer in the MOM_entrainment_diffusive module. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for some layer-mode configurations with a bulk mixed layer.
Added the new runtime parameter KPP_LT_MLD_GUESS_MIN to specify a previously hard-coded lower limit on the estimate of the boundary layer depth used to calculate the Langmuir number for some options with KPP. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for some configurations with a KPP and Langmuir enhanced turbulence.
Added the new runtime parameter REG_SFC_SUFFICIENT_ADJ to specify a previously hard-coded fraction of the target net entrainment to the mixed and buffer layers that is enough to stop the search for additional mass from the interior layers when regularizing the near-surface layers in layer-mode configurations. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for some layer-mode configurations with REGULARIZE_SURFACE_LAYERS=True.
Added the new runtime parameter SALT_EXTRACTION_LIMIT to specify a previously hard-coded limit on the fraction of the salt in a layer that can be extracted by the surface fluxes within a timestep. Also added do_not_log flags based on the value of ENABLE_THERMODYNAMICS to avoid logging parameters that are only used if thermodynamics are active in cases when it is not. In addition, the doxygen trailer describing this module had been inappropriately borrowed from another module, so it was completely rewritten to describe what the routines in this module actually do. The missing doxygen description of set_pen_shortwave was also added, and a number of spelling errors in comments were corrected. By default all answers are bitwise identical, but there is a new entry in the MOM_parameter_doc.all files for some configurations and meaningless entries have been removed from others.
Added the new runtime parameter MECH_TKE_FLOOR to specify a previously hard-coded tiny positive value for the remaining TKE when the bulk mixed does not yet have HMIX_MIN of fluid during mechanical entrainment. By default all answers are bitwise identical, but the MOM_parameter_doc.all files for some configurations with a bulk mixed layer and HMIX_MIN > 0 have a new entry.

Added the new runtime parameter VARYING_SPONGE_MASK_THICKNESS to specify a previously hard-coded input file thickness below which the target values in time-varying sponges are replaced with those from the layer above. By default all answers are bitwise identical, but the MOM_parameter_doc.all files for configurations with time-varying sponges have a new entry.

This PR adds 12 new runtime parameters to replace hard-coded dimensional parameters in 11 parameterization modules (MOM_lateral_mixing_coeffs.F90, MOM_internal_tides.F90, MOM_CVMix_KPP.F90, MOM_kappa_shear.F90, MOM_MEKE.F90, MOM_thickness_diffuse.F90, MOM_entrain_diffusive.F90, MOM_diabatic_aux.F90, MOM_bulk_mixed_layer.F90, MOM_ALE_sponge.F90 and MOM_regularize_layers.F90). The new runtime parameters that were added are MEKE_MIN_DEPTH_TOT, MEKE_LSCALE_MAX_VAL, EN_CHECK_TOLERANCE, MIN_DZ_FOR_SLOPE_N2, MEKE_MIN_DEPTH_DIFF, ENTRAIN_DIFFUSIVE_MAX_ENT, KD_SEED_KAPPA_SHEAR, KPP_LT_MLD_GUESS_MIN, REG_SFC_SUFFICIENT_ADJ, SALT_EXTRACTION_LIMIT, MECH_TKE_FLOOR and VARYING_SPONGE_MASK_THICKNESS).
This PR also includes a commit that makes the optional argument dz_subML to
diagnoseMLDbyDensityDifference()in MOM_diabatic_aux.F90 mandatory (via an error message) if it will be used, and changes a tiny floor on the minimum thicknessover which to apply buoyancy forcing in
applyBoundaryFluxesInOut()in a way that seems unlikely (but not impossible) to slightly change answers.The doxygen trailer describing the MOM_diabatic_aux module had been inappropriately borrowed from another module and did not describe the contents of that module at all, so it was completely rewritten to describe what the routines in this module actually do. The missing doxygen description of the subroutine
set_pen_shortwave()was also added.All answers are bitwise identical in the MOM6-examples test suite, but there are new entries in the MOM_parameter_doc.all files for configurations using the ten impacted modules.
