5030fa81a0 bug #49684, api_msg: treat non-blocking ERR_MEM as ERR_WOULDBLOCK 
This corrects a case in lwip_netconn_do_writemore() where if a
non-blocking socket receives ERR_MEM in a call to tcp_write(), it would
return ERR_MEM, which would result in ENOMEM coming out of the socket
layer

This case can be gracefully handled by returning ERR_WOULDBLOCK since the
socket is already marked as no longer writable and sent_tcp/poll_tcp will
mark the socket as writable again based on available buffer space

This is very similiar to how ERR_MEM is resolved for blocking sockets

9366c0eaab I decided to keep the "complexity" of handling IPv6 mapped IPv4 addresses out of netconn API. 
Only socket API understands this address type now.

180ba72a06 Dual-stack: Use IPv6 mapped IPv4 addresses in receive() and getaddr() only in socket API, not in netconn API. 
It is better to present correct IP types in netconn API.
Netconn API now accepts IPv6 mapped IPv4 addresses as well as IPv6 and IPv4 in send(), bind() and connect(), but does NOT map IPv4 to IPv6 mapped IPv4 in getaddr() and receive() functions.

1712b06a64 Work on dual-stack netconn 
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

#define lwip_htons(x) <your_htons>
