Log Message:
Update sysutils/rsyslog to 8.13.0.

Version 8.13.0 [v8-stable] 2015-09-22

- ZeroMQ enhancements:
  - Added the ability to set a static publishing topic per action as an
    alternative to constructing topics with templates
  - ZMQ_PUB socket now defaults to bind and ZMQ_SUB socket now defaults to
    connect
- Redis enhancements:
  - Can now LPUSH to a Redis list in "queue" mode
  - Can now PUBLISH to a Redis channel in "publish" mode
- build requirement for rsyslog/mmnormalize is now liblognorm 1.1.2 or above
- mmnormalize: liblognorm error messages are now emitted via regular
  rsyslog error reporting mechanism (aka "are now logged")
- add support for TCP client side keep-alives
- bugfix: imtcp/TLS hangs on dropped packets
- bugfix testbench: some tests using imptcp are run if module is disabled
- bugfix omkafka: Fixes a bug not accepting new messages anymore.
- bugfix: Parallel build issue "cannot find ../runtime/.libs/librsyslog.a:
    No such file or directory" (#479) fixed.
- bugfix: Added missing mmpstructdata testfiles into makefile.
- bugfix: Reverted FIX for issue #392 as it had unexpected side effects.
- The new fix duplicates the Listener object for static files (like
  done for dynamic files already), resolving issue #392 and #490.
- bugfix: issues in queue subsystem if syncqueuefiles was enabled
  - Error 14 was generated on the .qi file directory handle.
    As the .qi filestream does not have a directory set, fsync
    was called on an empty directory causing a error 14 in debug log.
  - When queue files existed on startup, the bSyncQueueFiles
    strm property was not set to 1. This is now done in the
    qqueueLoadPersStrmInfoFixup function.
- bugfix/testbench: tcpflood tool could abort when random data was added
- rscryutil: Added support to decrypt a not closed log file.
