21a08d6869 Empty DNS reply with OK status is another way to say NODATA. 
Sometimes DNS reply has nothing but query section. It does not look like
error, so it should be treated as NODATA with TTL=0 as soon as there is
no SOA record to deduce negative TTL from.

5208544edc Fix possible NULL-deref in evdns_cancel_request 
The clang static analyzer complained that base might be dereferenced
without being set, but this patch should fix another dereference issue.

9ed30de7ff Don't free evdns_request handles until after the callback is invoked 
Previously, once the callback was scheduled, it was unsafe to cancel
a request, but there was no way to tell that.  Now it is safe to
cancel a request until the callback is invoked, at which point it
isn't.

9c8db0f804 Fix all warnings in the main codebase flagged by -Wsigned-compare 
Remember, the code
   int is_less_than(int a, unsigned b) {
      return a < b;
   }
is buggy, since the C integer promotion rules basically turn it into
   int is_less_than(int a, unsigned b) {
      return ((unsigned)a) < b;
   }
and we really want something closer to
   int is_less_than(int a, unsigned b) {
      return a < 0 || ((unsigned)a) < b;
   }
.

Suggested by an example from Ralph Castain

e50c0fcc85 Use the _func() replacements for open, fstat, etc in evutil.c on win32 
Remember that in a fit of ANSI C compliance, Microsoft decided to
screw portability by renaming basically all the functions in unistd.h to
get prefixed with an understore.

For some reason, mingw didn't seem to mind, but at least some people's
compilers did: see bug 3044490.
