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 * Remove specific license info from outdated readme.txt, instead leave details to the source files.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.

Cycles: Replace own aligned allocator with system one This replaces our own implementation of aligned malloc with system calls, which depends on which operation system you're on. This is probably really minor noticeable change, but in the same time it might reduce amount of wasted memory.

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.

Cycles: Use size_t for aligned allocator Seems it got changes by accident to int during guarded allocation work, causing bad memory allocations.

Fix T53830: Cycles OpenCL debug assert on macOS, This was probably harmless besides some unnecessary memory usage due to aligning allocations too much.

Cleanup: refactor Cycles OSL texture handling This adds our own OSL texture handle, that has info for OIIO textures or our own custom texture types. A filename to handle hash map is used for lookups. This is efficient because it happens at OSL compile time, because the optimizer can figure out constant strings and replace them with texture handles.

/* Aligned new operator. */
Fix Cycles build error after recent changes We need to do aligned alloc of the services instead of globals now since the concurrent map moved there.
