o Minor bugfixes:
- Abort if tor_vasprintf fails in connection_printf_to_buf (a
utility function used in the control-port code). This shouldn't
ever happen unless Tor is completely out of memory, but if it
had happened and Tor somehow recovered from it, Tor could have
sent a log message to a control port in the middle of a reply to
a controller command. Fixes part of bug 3428.
