The socket creation code in mysql_backend.c wasn't MySQL specific and it could be used for all non-blocking network connections. Thus, it makes sense to move it to a common file where other protocol modules can use it. The address resolution code now uses `getaddrinfo` to resolve all addresses instead of manually handling wildcard hosts. This allows the same code to be used for all addresses.
