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
