Consolidate shutdown state.
fatal_alert isn't read at all right now, and warn_alert is only checked
for close_notify. We only need three states:
- Not shutdown.
- Got a fatal alert (don't care which).
- Got a warning close_notify.
Leave ssl->shutdown alone for now as it's tied up with SSL_set_shutdown
and friends. To distinguish the remaining two, we only need a boolean.
