Subject:	dhcp4 support listen on alias address when its main interface has null ipaddr

Hi Shawn Routhier,

My customer request bind dhcp server on alias address on dhcp4, so we have a patch below to support it.

Please help to review this patch, thanks a lot.

---

On linux, dhcp4 doesn't support listen on alias address when
its main interface has null ipaddr. dhcp3 support this function.
Because dhcp4 scan interface from /proc/net/dev, this is not enough.

On linux, both ioctl(,SIOCGIFCONF,) and
getifaddrs() could retrieve all ipaddrs on the linux system.

Below patch use getifaddrs as BSD as well.

---

Thanks

Kong Wei
