[LEDE-DEV] [PATCH] dnsmasq: add interface-name uci list.

[Daniel Danzberger]

This patch adds the interface-name option for each dhcp config
in /etc/config/dhcp.

With the interface_name option users can define a DNS name for each dhcp section
that will be resolved by dnsmasq with the underlaying interface address.

For example:
--
config dhcp 'lan'
	option interface 'lan'
	...
	list interface_name 'home.lan'
	...
--
