Log Message:
Update rsyslog to 8.4.2.

Version 8.4.2 [v8-stable] 2014-10-02
- bugfix: the fix for CVE-2014-3634 did not handle all cases. This is
  corrected now. see also: CVE-2014-3683
- fixed a build problem on some platforms. Thanks to Olaf for the patch
- behaviour change: "msg" of messages with invalid PRI set to \ 
"rawmsg"
  When the PRI is invalid, the rest of the header cannot be valid. So
  we move all of it to MSG and do not try to parse it out. Note that
  this is not directly related to the security issue but rather done
  because it makes most sense.

Version 8.4.1 [v8-stable] 2014-09-30
- imudp: add for bracketing mode, which makes parsing stats easier

  Thanks to Jared Johnson and Axel Rau for the patch.
- bugfix: imfile: if a state file for a different file name was set,
  that different file (name) was monitored instead of the configured
  one. Now, the state file is deleted and the correct file monitored.
