8 years ago I know it's dangerously close to release time, but I think this PR finally gets it right. Tested on linux-amd64 and windows-amd64.

DNS Lookup TCP Connection TLS Handshake Server Processing Content Transfer

After doing some additional testing, it appears that the GotConn hook fires after TLS has been established. TLS Handshake time is between ConnectDone and GotConn.
