Instead of trying to support both client and server in CLocalSocket, let's
have a specialized server class.
The basic usage is:
CLocalServer server;
server.listen("/tmp/name-of-portal");
server.on_ready_to_accept = [&] {
CLocalSocket* client = server.accept();
...
};
This will make things a lot simpler, since an accepting socket doesn't need
half of the stuff that a regular CIODevice provides. :^)
