[syslog-ng] multi-line logs and program/facility filters

Not sure in this specific case - but I parsed some multi-line logs where
the lines were not consecutive (i.e. related parts could come in anywhere
in the stream) and I had to resort to a program() to handle them.
I wrote something to identify log messages by key "IDs" and store the data
in a hash table until all the parts of the message were received (or a
timer expired) and then sent them along to the SIEM.
Hope that might help.
