Subject: x11vnc: 0.9.6 release.  Some strtok bugfixes. rename -tlsvnc to
 -anontls.  Disable ssl caching.  No cert creation prompting in inetd or bg
 modes.  waitpid a bit more carefully on ssl helpers.  Tune ssl initial
 timeouts.  Let -create user specify starting X display.  fix -rfbport prompt
 gui for older tk. -sslonly option. Error if no -ssl with related options.
 -rand option.  -ssl implies -ssl SAVE
