- change name of 'bytes' to 'xfrsize' in dns_db_getsize() parameter list and related variables; this is a more accurate representation of what the function is doing - change the size calculations in dns_db_getsize() to more accurately represent the space needed for a *XFR message or journal file to contain the data in the database. previously we returned the sizes of all rdataslabs, including header overhead and offset tables, which resulted in the database size being reported as much larger than the equivalent *XFR or journal. - map files caused a particular problem here: the fullname can't be determined from the node while a file is being deserialized, because the uppernode pointers aren't set yet. so we store "full name length" in the dns_rbtnode structure while serializing, and clear it after deserialization is complete.

# This value should be increased whenever changing the structure of
