5e9df2c698 lwip: fix broken default ICMPv6 handling of checksums. 
ICMPv6 should always have checksum generated for it as per RFC 3542
chapter 3.1.

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

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

8cb64698aa Allow backlog to be updated 
This commit adds support to the sockets and netconn layer to update the
backlog by calling listen when the netconn is already in the listen state.
When backlog is not enabled, the call returns successfully

This commit also introduces a macro for setting the backlog value that
prevents a 0 sized (invalid) backlog

11faa8149e Fix blocking close with LWIP_SO_SNDTIMEO 
This fixes a bug in close when LWIP_SO_SNDTIMEO is enabled, but
the option is not in use on the socket

A simple mis-typed comparison against zero would cause the close_timeout
to get set to zero if conn->send_timeout was 0

The intended check was to over-ride the default close timeout if a
send timeout had been specified via SO_SNDTIMEO
