Subject: [PATCH] dnsmasq: - make "name" option in "host" sections optional and
 append it to -G if set, allows specifying hostnames for static leases without
 resorting to /etc/hosts - implement "domain" sections, allows defining
 arbitary host names and associated ptr records from uci - bump package
 revision
