Sergey Sharybin a99d9ba635 Blender 3.6: Switch SVN to Git submodules using Git-LFS
This change makes it so build system and update utilities for Blender builds
are using pre-compiled libraries and other resources attached as Git modules
instead of using checkout of SVN repositories in the parent folder.

The directory layout:
```
  * release/datafiles/
    * assets/        -> blender-assets.git
      * publish/
      * ...
      * README.txt
  * lib/
    * darwin_x64/    -> lib-darwin_x64.git
    * darwin_arm64/  -> lib-darwin_arm64.git
    * linux_x64/     -> lib-linux_x64.git
    * windows_x64/   -> lib-windows_x64.git
  * tests/
    * data/         -> blender-test-data.git
```

The changes about configuring the actual Git sub-modules are not included
into this patch, as those require repository to actually exist before it
can be used.

The assets submodule is enabled by default, and the rest of them are
disabled. This means that if someone runs `git submodule update --init`
they will not get heavy libraries. The platform-specific and tests
related submodules are enabled when using `make update` or `make test`.

All the submodules are tracked: this means that when new commits are
done to the submodule, the blender.git repository is to be updated to
point them to the new hash. This causes some extra manual work, but it
allows to more easily update Blender and its dependencies to known good
state when performing operations like bisect.

Blender Convenience Targets
Provided for building Blender (multiple targets can be used at once).
* debug: Build a debug binary.
* full: Enable all supported dependencies & options.
* lite: Disable non essential features for a smaller binary and faster build.
* release: Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
* headless: Build without an interface (renderfarm or server automation).
* cycles: Build Cycles standalone only, without Blender.
* bpy: Build as a python module which can be loaded from python directly.
* developer: Enable faster builds, error checking and tests, recommended for developers.
* ninja: Use ninja build tool for faster builds.
* ccache: Use ccache for faster rebuilds.
Note: when passing in multiple targets their order is not important.
So for a fast build you can for e.g. run 'make lite ccache ninja'.
Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.
Note: passing the argument 'BUILD_CMAKE_ARGS=args' lets you add cmake arguments.
Other Convenience Targets
Provided for other building operations.
* config: Run cmake configuration tool to set build options.
* deps: Build library dependencies (intended only for platform maintainers).
The existence of locally build dependencies overrides the pre-built dependencies from subversion.
These must be manually removed from 'lib/' to go back to using the pre-compiled libraries.
Project Files
Generate project files for development environments.
* project_qtcreator: QtCreator Project Files.
* project_netbeans: NetBeans Project Files.
* project_eclipse: Eclipse CDT4 Project Files.
Package Targets
* package_archive: Build an archive package.
Testing Targets
Not associated with building Blender.
* test:
Run automated tests with ctest.
Static Source Code Checking
Not associated with building Blender.
* check_cppcheck: Run blender source through cppcheck (C & C++).
* check_clang_array: Run blender source through clang array checking script (C & C++).
* check_deprecated: Check if there is any deprecated code to remove.
* check_descriptions: Check for duplicate/invalid descriptions.
* check_licenses: Check license headers follow the SPDX license specification,
using one of the accepted licenses in 'doc/license/SPDX-license-identifiers.txt'
Append with 'SHOW_HEADERS=1' to show all unique headers
which can be useful for spotting license irregularities.
* check_cmake: Runs our own cmake file checker which detects errors in the cmake file list definitions.
* check_pep8: Checks all Python script are pep8 which are tagged to use the stricter formatting.
* check_mypy: Checks all Python scripts using mypy,
see: tools/check_source/check_mypy_config.py scripts which are included.
Documentation Checking
* check_wiki_file_structure:
Check the WIKI documentation for the source-tree's file structure
matches Blender's source-code.
See: https://wiki.blender.org/wiki/Source/File_Structure
Spell Checkers
This runs the spell checker from the developer tools repositor.
* check_spelling_c: Check for spelling errors (C/C++ only),
* check_spelling_osl: Check for spelling errors (OSL only).
* check_spelling_py: Check for spelling errors (Python only).
Note: an additional word-list is maintained at: 'tools/check_source/check_spelling_c_config.py'
Note: that spell checkers can take a 'CHECK_SPELLING_CACHE' filepath argument,
so re-running does not need to re-check unchanged files.
Example:
make check_spelling_c CHECK_SPELLING_CACHE=../spelling_cache.data
Utilities
Not associated with building Blender.
* icons:
Updates PNG icons from SVG files.
Optionally pass in variables: 'BLENDER_BIN', 'INKSCAPE_BIN'
otherwise default paths are used.
Example
make icons INKSCAPE_BIN=/path/to/inkscape
* icons_geom:
Updates Geometry icons from BLEND file.
Optionally pass in variable: 'BLENDER_BIN'
otherwise default paths are used.
Example
make icons_geom BLENDER_BIN=/path/to/blender
* source_archive:
Create a compressed archive of the source code.
* source_archive_complete:
Create a compressed archive of the source code and all the libraries of dependencies.
* update:
Updates git and all submodules and svn.
* update_code:
Updates git and all submodules but not svn.
* format:
Format source code using clang-format & autopep8 (uses PATHS if passed in). For example::
make format PATHS="source/blender/blenlib source/blender/blenkernel"
Environment Variables
* BUILD_CMAKE_ARGS: Arguments passed to CMake.
* BUILD_DIR: Override default build path.
* PYTHON: Use this for the Python command (used for checking tools).
* NPROCS: Number of processes to use building (auto-detect when omitted).
* AUTOPEP8: Command used for Python code-formatting (used for the format target).
Documentation Targets
Not associated with building Blender.
* doc_py: Generate sphinx python api docs.
* doc_doxy: Generate doxygen C/C++ docs.
* doc_dna: Generate blender file format reference.
* doc_man: Generate manpage.
Information
* help: This help message.
* help_features: Show a list of optional features when building.
