Implement the wget_with_dns() function which is needed by CONFIG_EFI_HTTP_BOOT=y. Note that there is no dependency added on CONFIG_CMD_DNS_LWIP because CONFIG_CMD_WGET_LWIP natively supports hostname resolution.

Calling a command directly feels a bit weird. Can we do this instead:

• Split do_wget in patch #7 and carve out 2 functions. The first will

prepare the arguments and the second will call httpc_get_file_dns() and run the loop

• Once that's split you can use the newly split function here and

avoid calling a command

Addressed in next version. I have implemented wget_with_dns() in patch #7 to that #9 doesn't need to add any code. And do_wget() simply calls wget_with_dns().

Thanks.
