Add support for rpc.ypxfrd and document it in the man page.

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.
