default tcp host

Right now if you dbus_server_listen("tcp:port=0") it listens on localhost.
But there's no way right now to listen on INADDR_ANY (all local interfaces).
If we made a missing host= mean INADDR_ANY instead of localhost, there
would be a problem however; the DBusServer would not have any way to
report its own address. (Right? I'm not exactly an expert here.)
So here is a proposal, that we add to the tcp: address format the flag
Which would mean to bind to INADDR_ANY (I believe that is equivalent to
not binding at all, just listen()).
The host= field would continue to default to localhost if missing, and
will be the host the server will report if asked for its address.
So basically if you say tcp:host=foo,port=0,all_interfaces=true then the
server will report its address as tcp:host=foo,port=something and will
in fact be listening on all local interfaces. If you say
all_interfaces=false, then the server will only listen on the host that
was specified. This can remain the default, so back compat would not be
I'll poke at implementing this now and maybe some obvious problem with
it will emerge.
