net: Dial/ListenPacket w/ "ip:protocol" net string doesn't work well

[mikioh]

On tip:
a) Dial cannot accept "ip:protocol" as net string,
b) ListenPacket has a bug which is misunderstanding on an err value from splitNetProto.

Hey Mikioh,
I wanted to look into this today, but I'm unable to reproduce issues with Dial
(net.Dial("tcp", "127.0.0.1:http") worked fine for me on current tip, and I was able to
read/write data on the returned TCPConn), and I don't quite understand what you mean
with regards to ListenPacket handling errors from splitNetProto. Could you provide some
sample code and / or explain further?
Thanks much!

Comment 4:

a) Dial("ip4:ospf", ...) dosen't work well. Also it might be nice if the 
Dial for raw IP sockets works with "" addr string.
b) In LinstenPacket "if rawnet, _, err = splitNetProto(net); err != nil" 
is wrong.
