net: refactor sslconfig to not depend on LuaSec
This now requires that the network backend exposes a tls_builder
function, which essentially wraps the former util.sslconfig.new()
function, passing a factory to create the eventual SSL context.
That allows a net.server backend to pick whatever it likes as SSL
context factory, as long as it understands the config table passed by
the SSL config builder. Heck, a backend could even mock and replace the
entire SSL config builder API.
