Several places print the changeset action with node and property
details. Refactor these into a common printing helper. The complicating
factor is some prints are debug and some are errors. Solve this with a
bit of preprocessor magic.

v3:
- Drop printing changeset entry pointers
v2:
- Split out refactoring from fix in prior patch
- Avoid pr_cont and relying on pr_debug return value which dynamic
debug doesn't have
