Adjusted ENOBUFS logging level. On local datagram sockets ENOBUFS might legitimately appear due to insufficient space in socket buffers, as seen on BSD systems. Accordingly, ngx_connection_error() now logs it with logging level set for the particular connection errors, either "info" or "error" (instead of "alert", which was previously used).
