8611c37f97 Cycles: Generate OSL closures using macros and a template file
This has the advantage of being able to use information about the
existing OSL closures in various places without code duplication. In
addition, the setup code for all closures was moved to standalone
functions to avoid usage of virtual function calls in preparation for GPU
support.

This patch was split from D15902.

ef7c9e793e Cycles: Remove separate OSL attribute map and instead always use SVM attribute map
The SVM attribute map is always generated and uses a simple
linear search to lookup by an opaque ID, so can reuse that for OSL
as well and simply use the attribute name hash as ID instead of
generating a unique value separately. This works for both object
and geometry attributes since the SVM attribute map already
stores both. Simplifies code somewhat and reduces memory
usage slightly.

This patch was split from D15902.

2c1bffa286 Cleanup: add verbose logging category names instead of numbers
And use them more consistently than before.

578771ae4d UDIM: Add support for packing inside .blend files
This completes support for tiled texture packing on the Blender / Cycles
side of things.

Most of these changes fall into one of three categories:
- Updating Image handling code to pack/unpack tiled and multi-view images
- Updating Cycles to handle tiled textures through BlenderImageLoader
- Updating OSL to properly handle textures with multiple slots

9cfc7967dd Cycles: use SPDX license headers
* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
  to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.

b4d9b8b7f8 Fix T91893, T92455: wrong transmission pass with hair and multiscatter glass
We need to increase GPU memory usage a bit. Unfortunately we can't get away
with writing either reflection or transmission passes because these BSDFs may
scatter in either direction but still must be in a fixed reflection or
transmission category to match up with the color passes.

fd25e883e2 Cycles: remove prefix from source code file names
Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.

d7d40745fa Cycles: changes to source code folders structure
* Split render/ into scene/ and session/. The scene/ folder now contains the
  scene and its nodes. The session/ folder contains the render session and
  associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
  kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
