[collectd] [PATCH] set SO_REUSEADDR on socket so multiple listeners can share port

[Pavel Shramov]

Sorry for bare patch without any comments.

This patch allows programs other then collectd to listen on same port on
same multicast address. For example unicast proxy that forwards all
packets to another collect instance (or to monitoring system).

Of course this may be achieved using tunnels/multicast routing but proxy
is much more simple (script is ~10 lines of python code or ~20 lines of C code)

I't would be great if this patch will be included into collectd.
