dnsmasq: Multiple dnsmasq instances support
Adds support in uci for configuring multiple dnsmasq instances via multiple dnsmasq sections. The uci sections host, boot, mac, tag, vendorclass, userclass, circuitid, ... will refer to a dnsmasq instance via the instance parameter defined in the section; if the instance parameter is not specified backwards compatibility is preserved. Start/Stopping a dnsmasq instance can be achieved by passing the dnsmasq instance name as argument to start/stop via the init script. Multiple dnsmasq instances is usefull in scenarios where you want to bind a dnsmasq instance to an interface in order to isolate networks. This patch is a rework of a multiple dnsmasq instance patch by Daniel Dickinson Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
