Handle EAGAIN and EWOULDBLOCK more gracefully when dealing with safe_read(). All occurrences of safe_read() should only be invoked on fds that have signaled ready-to-read state via the epoll() mechanism, so this change should not result in any observable difference, but it is best to be safe. Additionally, a constant stack variable is converted to an equivalent macro define for cleanliness. Finally, print the error type encountered if reading data from an ARP response fails with a read error.
