evilnet/nefarious2 ? reverse-engineered prompt

Build me a working IRC server daemon based on this project, with the same Nefarious 2 behavior described in the README.

I want it to compile cleanly, run reliably on Linux, FreeBSD, and Solaris style systems, and support the performance improvements this project talks about, like async event handling and handling lots of clients efficiently. Please make sure the config system works, including feature lines, GET and SET commands, and the P10 protocol support mentioned in the docs. It should also support the account feature so users can stay logged in through a netsplit.

If there are any missing pieces or old build issues, please fix them so I can build and run it from scratch. Also make the Docker setup usable, with the exposed IRC and SSL ports working and sensible defaults for the server name, description, numeric, and admin contact info. If you need to check current docs or platform details online, go ahead and do that.
