Prep v233: Add missing files from upstream and rename formats-util.[hc]
Some functionality has been exported to the following files: - src/basic/env-util.[hc] - src/basic/exec-util.[hc] - src/shared/nsflags.[hc] The content of these files is now needed in elogind, and the files have been added as-is. Cleanup is done later. Further the header src/basic/formats-util.h has been renamed to src/basic/format-util.h
