Subject: journal-remote: implement inheriting http(s) sockets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now --listen-http=-3 --listen-https=-4 can be used to spawn a µhttpd
server on those two ports, in http and https modes respectively.
As before, --listen-http=3 --listen-https=4 will launch µhttpd servers
on ports 3 and 4.
