Rename modules in `./scripts/modules/` to use an underscore prefix to make it clear they aren't intended to be part of public API's. This also means there is no implication that these modules should be stable, allowing us to change them based on Blender's internal usage. The following modules have been marked as private: - `animsys_refactor` - `bl_console_utils` - `bl_i18n_utils` - `bl_previews_utils` - `bl_rna_utils` - `bl_text_utils` - `bl_ui_utils` - `bpy_restrict_state` - `console_python` - `console_shell` - `graphviz_export` - `keyingsets_utils` - `rna_info` - `rna_manual_reference` - `rna_xml` Note that we could further re-arrange these modules (under `_bpy_internal` in some cases), this change is mainly to mark them as private, further changes can be handed on a case-by-case basis.
