Patch from rovv: when we have no pending streams, choose exits with choose_good_exit_server_general() rather than with circuit_get_unhandled_ports() and friends. Bugfix on 0.1.1.x, at least.

     - Minor fix in the warning messages when you're having problems
       bootstrapping; also, be more forgiving of bootstrap problems when
       we're still making incremental progress on a given bootstrap phase.
+    - When we're choosing an exit node for a circuit, and we have no pending
+      streams, choose a good general exit rather than one that supports "all
+      the pending streams".  Bugfix on 0.1.1.x. (Fix by rovv.)
