Changes in v3:
- Elaborate on first commit message.
- Fix SP violations in lib-log-graph.

Changes in v2:
- Arrange patches by functions changed instead of files changed.
- Rename library functions by prepending 'lib_'.
- Drop outdated sanitization calls to sed.
- Create specialized helpers to reduce code noise.
- Fix style violations.

This round looks quite polished.  I'll queue after massaging the log
message of the first step.

Thanks.
