 In testing Tor Launcher changes while working on #9445, Kathy Brade and I
 found that when tor is only configured with bridges it cannot use due to a
 lack of PT plugins, the bootstrap process just stops making progress.  It
 would be much better if an error was reported via the control port.  Here
 is our torrc:

 AvoidDiskWrites 1
 bridge obfs2 91.143.91.97:34770
 ControlPort 9151
 CookieAuthentication 1
 DataDirectory /Users/brade/dev/tor/tbb-for-tl-
 testing/TBB-3.0a2.app/Contents/Resources/Data/Tor
 DirReqStatistics 0
 GeoIPFile ../../Contents/Resources/Data/Tor/geoip
 Log notice stdout
 SocksListenAddress 127.0.0.1
 SocksPort 9150
 UseBridges 1

 Here is the tor log:

 a pluggable transport proxy supporting 'obfs2'. This can happen if you
 haven't provided a ClientTransportPlugin line, or if your pluggable
 transport proxy stopped running.
