[rsyslog] Losing UDP packages

[Rainer Gerhards]

I just committed the functionality:

http://git.adiscon.com/?p=rsyslog.git;a=commitdiff;h=cc8237736d11b54a3d6089d8
36da7ccb6972a29c

Note that I am far from being an autotools expert, so I would appreciate if
you could provide proper configure checks. I did only a very rough test of
the functionality.

Thanks,
Rainer
