File headers: SPDX License migration Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers.

Cleanup: avoid debug-only includes for BLI_assert.h Having includes in debug builds makes it possible to accidentally break release builds. Avoid this by moving calls to other modules out of BLI_assert.h into BLI_assert.c 2020-08-06 20:17:44 +10:00			`#include <stdlib.h>`
