[PATCH] add interface and hosts parsing from uci dhcp config to ISC dhcpd (fix bridges)

[PATCH] add interface and hosts parsing from uci dhcp config to ISC dhcpd (fix bridges)
This allows people to use the luci interface to specify to dhcpd which
interfaces it should listen to, and which static MAC->IP host mappings
should it define
For the interface, this has to be done in the initscript, via
commandline when the server is started
For the static hosts, the initscript makes a file called
/tmp/dhcpd.hosts which you can include in your dhcpd.config to use the
webgui defined hosts
Fix: 7.5.2011. Now works properly on interfaces which are in a bridge
