* upstream lwIP is now downloaded by a makefile, not subsubmoduled * lwip2: upstream lwIP not sub-sub-modules anymore lwip2: Allow IPv4 and IPv6 DNS and SNTP server configured via DHCP to co-exist (patch against upstream) * lwip2: enable tcp-listen-with-backlog feature * lwip2 submodule update: - enable more efficient chksum algorithm thanks to Richard Allen - enable tcp listener with backlog * more comments, fix backlog management, fix API * move default value definition in .cpp because one must not believe it can be redefined before including WiFiServer.h * improved backlog handling, it is no more a breaking change
