[Click] IPv6 compilation error with NSClick

[Eddie Kohler]

Hi Wim,

This is a strange and unfortunate error. It arises because 
click_in6_addr is declared in the global namespace, for some reason, 
rather than in the "Click::" namespace (CLICK_DECLS/CLICK_ENDDECLS); but 
"confparse.hh" mistakenly declared a version of this symbol in the 
"Click::" namespace. That was the symbol that the compiler thought was 
undefined.

Commit 58af73b fixes this problem.

Thanks
E
