Generic sockets && Unix Socket support

[Nukesor]

Resolves #90

This PR adds generic streams/listeners and support for UnixSockets.

What still needs to be done:

• Move the socket code to the platform specific code
• Make a unix platform for shared code between linux and macOs
• On daemon start: Check whether he unix socket exists. If it exists, check if you can connect.
  If one can connect, abort and write an error message.
  If we cannot connect, remove the socket and continue normal operations.
• Maybe get those generic Traits better names.
