This commit add the ability for ctrld to gather client information, including mac/ip/hostname, and send to Control-D server through a config per upstream. - Add send_client_info upstream config. - Read/Watch dnsmasq leases files on supported platforms. - Add corresponding client info to DoH query header All of these only apply for Control-D upstream, though.
