Description of problem:

recent upgrade from 3.1.4 to 3.2.4 breaks existing logging because local logsources are now expressed as 'hostname/hostname' instead of 'localhost@hostname'.  Beside the changed name, the '/' prevents creation of logfiles based on $FULLHOST.



E.g. the sample configuration

on a client logs to a server with

| destination d_iptables	{ file("/var/log/remote/IPTABLES/log.$FULLHOST" sync(10)); };


With 3.1.4 it wrote e.g. to 'log.localhost@walther'. Now, it fails with

| Error opening file for writing; filename='/var/log/remote/IPTABLES/log.walther/walther', error='No such file or directory (2)'
