fill memfile v6 BLQ tables
At least these following steps:
- add a flag in lease object to unchange, remove or update entries in the new BLQ tables for the lease (this avoids to change the API to add a new parameter to updateLease methods)
- revamp the updateLeaseXExtendedInfo methods
- update memfile lease manager methods to act on these tables
- fill these tables when loading memfile files
- add a new command to (re)build the tables (note as it is useless for memfile which do this when it loads files it can be postpone)
