net,dgram: add ipv6Only option for net and dgram
For TCP servers, the dual-stack support is enable by default, i.e.
binding host "::" will also make "0.0.0.0" bound. This commit add
ipv6Only option in `net.Server.listen()` and `dgram.createSocket()`
methods which allows to disable dual-stack support. Support for
cluster module is also provided in this commit.
