experimental: add fdl (Full Data Logging) translator
NSR needs logging that is different than our existing changelog in
several ways:
* Full data, not just metadata
* Pre-op, not post-op
* High performance
* Supports the concept of time-bounded "terms"
Others (for example EC) might need the same thing. This patch adds such
a translator. It also adds code to dump the resulting journals, and to replay
them using syncops, plus (very rudimentary) tests for all of the above.
