socket-util: Generalize tcp_open_*() to UDP, as inet_open_*().

Browse Source 
The tcp_open_active() and tcp_open_passive() functions don't really have
any strong dependencies on TCP.  With a couple of simple changes they
can be used for UDP also.  Since this is useful for Netflow, this commit
does so.
