    - Fix a crash when handling the SIGNAL controller command or
      reporting ERR-level status events with bufferevents enabled. Found
      by Robert Ransom. Fixes bug 3367; bugfix on 0.2.3.1-alpha.
Add, use a bufferevent-safe connection_flush() A couple of places in control.c were using connection_handle_write() to flush important stuff (the response to a SIGNAL command, an ERR-level status event) before Tor went down. But connection_handle_write() isn't meaningful for bufferevents, so we'd crash. This patch adds a new connection_flush() that works for all connection backends, and makes control.c use that instead.
