* refactor management of cluster recovery version (crv)
- send the crv to tlogs as they rejoin cluster during recovery, not
just when an rv is computed.
- if a tlog has not yet received the crv, wait for it
* Propagate cluster recovery version to tlog for version vector recovery
Enable RECORD_RECOVER_AT_IN_CSTATE to store recovery version in cstate
* respond to review comments
* - dont sent rv to old tlog generations
- send crv after locking, if rv computed
* Remove CRV RPCs, have cursor pad beyond end tlog to RV
* Send end version in peek request to facility vv recovery
* Fix serialization in peek request interface.
