sock: Introduce named constants for sk_reuse
Name them in a "backward compatible" manner, i.e. reuse or not are still 1 and 0 respectively. The reuse value of 2 means that the socket with it will forcibly reuse everyone else's port. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
