[v9_11] store "addzone" zone config in a NZD database 4421. [func] When built with LMDB (Lightning Memory-mapped Database), named will now use a database to store the configuration for zones added by "rndc addzone" instead of using a flat NZF file. This improves performance of "rndc delzone" and "rndc modzone" significantly. Existing NZF files will automatically by converted to NZD databases. To view the contents of an NZD or to roll back to NZF format, use "named-nzd2nzf". To disable this feature, use "configure --without-lmdb". [RT #39837]
