#197: module-tunnel-sink segfaults without sink argument set

 I've been toying around with module-tunnel a bit, and found it
 segfaulted when I tried it. I'm using 0.9.8, but module-tunnel hasn't
 been modified since that release AFAICS.

 After finally getting gdb to work, I found that the problem lies at
     if (strcmp(name, u->sink_name))

 Here, u->sink_name is NULL. Some tracing back leads me to
     u->sink_name = pa_xstrdup(pa_modargs_get_value(ma, "sink", NULL));;

 So, the problem was that I didn't specify a "sink" argument to
 module-tunnel-sink. Adding the sink argument, seems to make the module
 work (though I have no full testing setup here).

 Still, this is a problem in the source code. It should either complain
 about a missing "sink" option, or properly handle the lack of a "sink"
 option. Perhaps it should use the first available sink or something?
