Comment (by arma):

 If you merge this patch, stuff gets better, but not completely better.
 People who switch between multiple PTs, and who try to use PTs that
 shoehorn their network design into our bridge design (currently meek and
 flashproxy, with their "I'll just say there's a bridge on 127.0.0.1:9060
 and never you mind that there's a whole internet behind that one bridge"),
 will become much happier when they're on not-perfectly-stable network
 connections.

 People who are in the above situation, who have two bridges in their state
 file which offer different PTs but which use the same bridge identity
 fingerprint, will not see an increase in happiness from this patch. That's
 because node_is_a_configured_bridge(node) says "yes" if node's identity
 fingerprint is a configured bridge, even if the PT offered by node isn't
 the one that's configured.
