Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

The following parameters should be tunable at compile time. Some of them exist as sysctls too.
This is far from complete

NetROM parameters are tunable via an ioctl passing a struct
