lwip2 updates: no more git sub-sub-module deps, faster checksum, backlog limitation and other fixes (#6887)

Browse Source 
* 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
