[PATCHv4 0/5] net/lwip: add lwip library for the network stack

[Maxim Uvarov]

changelog:
	v4: - tested with tests/py/ did some minor fixes (out of tree
		build, variables set after downloads).
	    - accounted review comments for documentation.
	    - implemented dns command
            - corrected wget command to not use serverip variable and use just
		url string.
	v3: - use lwip commands for ping,tftp,wget,dhcp if this patch
	      applied. Drop CONFIG_LIB_LWIP_REPLACE_<COMMAND> option.
	    - docs: use rst variant and drop references to RFC.

build:
	git submodule init
	git submodule update
	make 

I tested with qemu and ubuntu host for the server manually and with
./test/py/test -bd qemu_arm64 --build -k net.
