bg- fb94d50410 Change typedef of uip_ipaddr_t from a vector type to a union.
typedef union uip_ip4addr_t {
  u16_t u16[2];
  u8_t  u8[4];
} uip_ip4addr_t;

typedef uip_ip4addr_t uip_ipaddr_t;

This implies that one must consistently pass pointers to
uip_ipaddr_t:s and not mix and match pointers with
uip_ipaddr_t:s as was done earlier.
