net: rename internal functions for readability
The current namings are a bit confusing and hard to be searched for.
- Rename listen to listenInCluster
- Rename _listen2 to _setUpListenHandle
- Remove _listen since it's a one-liner only used in one place
- Correct comments in server.listen
Also Socket.prototype.listen
doesn't seem to be tested nor documented, added a FIXME.
