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.
