This commit adds W5500 W5100 and ENC28j60 drivers from @njh with credits They are available in libraries/ An example is added in W5500 examples directory plus: * Extract dhcp server from lwip2 and add it to the core as a class. It must always be present, it is linked and can be called by fw on boot. So it cannot be stored in a library. * ethernet: static or dhcp works * PPPServer: example * bring WiFi.config() to the lwIP generic interface (argument reorder common function) * move hostname() from WiFI-STA to generic interface * remove non readable characters from dhcp-server comments * dhcp-server: magic_cookie is part of bootp rfc * fixes from https://github.com/d-a-v/W5500lwIP/issues/17 * enable lwip_hook_dhcp_parse_option() * +ethernet tcp client example in w5500 library examples
