Work on dual-stack netconn

Browse Source 
IPv6 netconns are created as IPADDR_TYPE_ANY raw/udp/tcp PCBs internally
bind, connect and sendto now accept IPv6 mapped IPv4 addresses or IPv4 addresses as argument
getaddr and receive functions now return IPv6 mapped IPv4 addresses instead of IPv4 addresses
This behavior is close to BSD socket API
