liblogging

Version 7.6.0 [v7.6-stable] 2014-01-??
This starts a new stable branch based on 7.5.8 plus the following changes:

• bugfix: imuxsock input parameters were not accepted due to copy&paste error.
  Thanks to Andy Goldstein for the fix.
• added ProcessInternalMessages global system parameter
  This permits to inject rsyslog status messages into *another* main syslogd or the journal.
• new dependency: liblogging-stdlog (for submitting to external logger)
• bugfix: json templates are improperly created
  Strings miss the terminating NUL character, which obviously can lead to all sorts of problems.

  Thanks to Alain for the analysis and the patch.
• ompgsql bugfix: improper handling of auto-backgrounding mode
  If rsyslog was set to auto-background itself (default code behaviour, but many distros now turn it off for good reason), ompgsql could not properly connect. This could even lead to a segfault. The core reason was that a PG session handle was kept open over a fork, something that is explicitely forbidden in the PG API.
  Thanks to Alain for the analysis and the patch.
