This is a wrapper around getifaddrs(2), which is in libreplace, so should always be available. Some users want to set net.ipv4.ip_nonlocal_bind = 1. So, CTDB needs a way of testing if public IPs are present, without using bind(2). Doing all of this unconditionally in ctdb_sys_have_ip() will be inefficient in the recovery daemon's local IP verification if there are a lot of IP addresses. Split it this way so the interface information can be retrieved once and used multiple times. This doesn't appear to need IP canonicalisation for IPv4-mapped IPv6 addresses.
