  o Minor bugfixes
    - Correctly detect failures to create DNS requests when using Libevent
      versions before v2.  (Before Libevent 2, we used our own evdns
      implementation.  Its return values for Libevent's evdns_resolve_*()
      functions are not consistent with those from Libevent.) Found by
      Lodger; fixes bug 2363; bugfix on 0.2.2.6-alpha.
Fix check for failed evdns request creation When using libevent 2, we use evdns_base_resolve_(). When not, we fake evdns_base_resolve_() using evdns_resolve_*(). Our old check was looking for negative values (like libevent 2 returns), but our eventdns.c code returns 1. This code makes the check just test for nonzero. Note that this broken check was not for _resolve_ failures or even for failures to _launch_ a resolve: it was for failures to _create_ or _encode_ a resolve request.
