- Prefer ipv6 for listen addrs if available
If the listen address allows for ipv4 or ipv6 values we want to prefer
ipv6 if the host is configured with working ivp6. We add the ai_flag
AF_ADDRCONFIG to filter out ipv6 (and ipv4) if the host isn't configure
for this AF_INET version. Then we sort based on the family to prefer
ipv6 over ipv4.
The reason for this is clients will prefer ipv6 before falling back to
ipv4 when attempting to connect to a hostname. If the server isn't
listening on ipv6 this makes new connections happen slowly.

- Add support for keepalive to client
A gearman client only waiting for jobs will wait indefinitely if the
gearman server vanishes (e.g. due to a VM crash). In this case there
is no traffic on the connection and the client blocks forever if there
is nothing in between that forcefully terminates the connection.
Adding tcp keepalive can mitigate that and the connection will be
terminated by the kernel in this situation which then triggers a
reconnect.
