mark various functions as static By marking all those function as static, the compiler is free to do more optimizations. In addition, those functions are not used outside server.c

simplify handle_cgi Now that I got rid of the enum+switch, adding more state is easier. Before, we used an hack to remember if we had read the CGI reply or not (c->code = -1). This introduces a new state, handle_cgi_reply that reads the CGI script reply, logs it, and only then switches to handle_cgi. handle_cgi itself is cleaner, now it only reads into c->sbuf and send what it had red. We even get, almost for free, the 42 error. If read exists with -1 or 0 from in handle_cgi_reply, we return a proper error to the client. We can extend this further in the future and also try to validate the CGI reply (for now we're only looking for a \n).

invert the location precedence: first match wins It's how httpd(8) does it, and it allows us to call fnmatch less time
