renderd does not listen on unix and TCP sockets.

[StyXman]

I'm configuring renderd on a separate machine than the one wit Apache/mod_tile, so I'm obliged to put this in renderd.conf:

iphostname=0.0.0.0
ipport=7654

But if I also want to test that it's running properly with render_list, I need the Unix socket, because I can't tell it the IP/port to connect to, so:

socketname=/var/run/renderd/renderd.sock

renderd ignores the latter:

Sep 16 11:47:16 diablo renderd[4832]: config renderd: ip socket=0.0.0.0:7654
Sep 16 11:47:16 diablo renderd[4832]: config renderd: num_threads=2tile
Sep 16 11:47:16 diablo renderd[4832]: config renderd: num_slaves=0
Sep 16 11:47:16 diablo renderd[4832]: config renderd: tile_dir=/var/lib/mod_tile
Sep 16 11:47:16 diablo renderd[4832]: config renderd: stats_file=/var/run/renderd/renderd.stats

Maybe the easiest way to solve this is to teach render_* to use a TCP/IP address.
