The kernel is applying the RA managed/otherconf flags silently and
forgets to send ifinfo notify to inform about their change when the
router provides a zero reachable_time and retrans_timer as dnsmasq
and many routers send it, which just means unspecified by this router
and the host should continue using whatever value it is already using.
Userspace may monitor the ifinfo notifications to activate dhcpv6.

Rule insertion may fail on systems where libc doesn't provided zeroed
memory via malloc (which is legal).
IOW, this was never guaranteed to work correctly.
Add a xzalloc wrapper to do error checking and zeroing and then
use it in libebtc.
