Comment:

 A patch against tor master that adds this functionality.  The only
 pluggable transport currently capable of using it is my obfsproxy branch
 linked of #8956.

 I'm not sure what is supposed to happen if the user edits the torrc to
 specify a different proxy (eg changing from nothing to SOCKS5, or SOCKS5
 to HTTPS).  The existing code probably won't detect this as something
 worthy of restarting all the pluggable transports, so I think I need to
 add code to detect this in or/transports.c/proxy_needs_restart(), along
 with caching the previously configured proxy settings.
