This adds support for parsing RTM_NEWADDR and RTM_DELADDR netlink messages received on netd's netlink socket and formatting them them so NetlinkHandler can process them. Address changes are notified in subsystem "address". Interface changes, which used to be notified in subsystem "net", are now notified in subsystem "interface" to avoid confusion.
