netifd: Link layer state awareness support on device level
Device layer is informed by netlink events regarding the link layer status. Link
layer status change results in a DEV_EVENT_LINK_UP/DEV_EVENT_LINK_DOWN broadcast
event for a given device.
Depends on uloop error callback patch.
Solves issue reported in https://dev.openwrt.org/ticket/14590
