of: dynamic: Refactor changeset action printing to common helpers

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.

Some cases printed the 'cset' which was the changeset entry pointer
rather than the whole changeset itself. The changeset entry is not all that
interesting and gets obfuscated by default anyways. So just drop it.
