License Headers: Set copyright to "Blender Authors", add AUTHORS Listing the "Blender Foundation" as copyright holder implied the Blender Foundation holds copyright to files which may include work from many developers. While keeping copyright on headers makes sense for isolated libraries, Blender's own code may be refactored or moved between files in a way that makes the per file copyright holders less meaningful. Copyright references to the "Blender Foundation" have been replaced with "Blender Authors", with the exception of `./extern/` since these this contains libraries which are more isolated, any changed to license headers there can be handled on a case-by-case basis. Some directories in `./intern/` have also been excluded: - `./intern/cycles/` it's own `AUTHORS` file is planned. - `./intern/opensubdiv/`. An "AUTHORS" file has been added, using the chromium projects authors file as a template. Design task: #110784 Ref !110783.

Cleanup: Add a copyright notice to files and use SPDX format A lot of files were missing copyright field in the header and the Blender Foundation contributed to them in a sense of bug fixing and general maintenance. This change makes it explicit that those files are at least partially copyrighted by the Blender Foundation. Note that this does not make it so the Blender Foundation is the only holder of the copyright in those files, and developers who do not have a signed contract with the foundation still hold the copyright as well. Another aspect of this change is using SPDX format for the header. We already used it for the license specification, and now we state it for the copyright as well, following the FAQ: https://reuse.software/faq/

Freestyle: View map caching. New render layer option named "View map cache" is added to reuse a previously computed view map for subsequent rendering. The cache is automatically updated when the mesh geometry of the input 3D scene has been changed. This functionality offers a major performance boost for Freestyle animation rendering when camera-space mesh geometry is static, as well as for repeated still renders with updates of line stylization options. Although the "View map cache" toggle is a render layer option, the cache memory is shared by all render layers and scenes. This means that if Freestyle is used for two or more render layers (possibly in different scenes through the compositor), then the cached view map for one render layer is replaced by a new view map for another render layer and hence no performance gain is expected.

Core: remove WITH_CXX_GUARDEDALLOC option This implements the proposal from #124512. For that it contains the following changes: * Remove the global override of `new`/`delete` when `WITH_CXX_GUARDEDALLOC` was enabled. * Always use `MEM_CXX_CLASS_ALLOC_FUNCS` where it is currently used. This used to be guarded by `WITH_CXX_GUARDEDALLOC` in some but not all cases. This means that a few classes which didn't use our guarded allocator by default before, are now using it.

Clang-Format: Allow empty functions to be single-line For example ``` OIIOOutputDriver::~OIIOOutputDriver() { } ``` becomes ``` OIIOOutputDriver::~OIIOOutputDriver() {} ``` Saves quite some vertical space, which is especially handy for constructors.

Cleanup: typedef uchar, ushort, uint & ulong in freestyle source/blender/freestyle wasn't fillowing Blender's own conventions for integer types. This had the down-side of making the code_clean.py utility attempt to replace `unsigned int` types which always failed. While this edit could have been manually ignored for all files in freestyle, add the typedef's to `FreestyleConfig.h` and follow Blender's convention instead.
