This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Also generallize the yp_dbwrite functions a little: allow the caller
to specify certain flags. I need this mostly for some changes to
rpc.yppasswdd to allow in-place updates.
Also change Makefile a little to use the same format as ypserv.
- Handle 'empty' maps more gracefully. By empty I mean a valid map that
just happens not to have any entries in it, such as you would get if
you built a map database from an empty file. Previously, trying to
ypxfr such a map would yield an 'NIS map/database error' which is not
the correct behavior.
ypxfr_misc:
- Make sure to free() or xdr_free() dynamically allocated memory in
ypxfr_get_master() as necessary.
