rsyslog work log 16

Yesterday’s rsyslog work log:
– begun to work a bit on BSD portability issues
– changed imklog to a driver interface
imklog now uses os-specific drivers. The initial “set” contains
the linux driver. This is a prequisite for BSD klog, which can
now be implemented on that driver interface.
– improved detection of modules being loaded more than once
thanks to varmojfekoj for the patch (v3-stable)
– released 3.14.2
