This commit introduces the lower layer in the new layered minivpn architecture. This new architecture has already been implemented in an integration branch. The general idea is to split functionality by layers that we can reason about and write tests for more easily. Each layer will communicate with other layers through channels. Also, each layer will run a bunch of worker for performing channel or network-based I/O. Here, in particular, we're adding the network I/O layer on top of which the rest of the architecture is based, as well as all the required dependencies for making the code compile.
