Misc/codecleanup (#29)
* Intermediate changes for Connected UDP. * Add more changes to support connected UDP. There is an issue with this approach, as multiple sockets are not able to listen on connected UDP. We need to add SO_REUSEPORT to make this a viable solution. This would be done in a later commit but before this change is merged into master. * Minor code cleanup.
