 Now that TBB sets socksport auto, we have a number of users who try to use
 their other apps with Tor and find that port 9050 mysteriously doesn't
 work.

 One answer is for them to run two Tors, one that's TBB that's for
 browsing, and another that's the "system" tor for other things. That's a
 bad answer, among other reasons because we don't have a good 'system tor'
 package for them to easily install, and we don't have excess packager time
 to add one to our stack.

 Another answer is to tell users who want to run other apps too to go edit
 their tbb's torrc to pick 9050 as its socks port. We should explore
 exactly what steps this would take, but it's not a good long-term solution
 either.

 Another answer is that Tor ought to try 9050 first and fall back to
 something else if that fails to bind (or fails to be usable, per #3943).
 That answer isn't perfect since it will still produce mysterious failures
 if you try to run a Tor instance that demands to bind to 9050. But I think
 it's the best one we've got.

 In the mean time, perhaps we should disable the 'socksport auto' thing in
 the TBB's we ship. Or perhaps we should do that only for certain OSes,
 e.g. Windows which has a related problem already (#3941).
