Fix a longstanding bug in eventdns related to timeouts:  The timeout count was never actually reset to 0.  Argh.  Now we reset it to zero after we get a successful request, or after we notice that a nameserver is back up, or after we decide the nameserver is down because of timeouts.  This may fix bug 326.

Try to compile with fewer warnings on irix64's MIPSpro compiler /
 environment, which apparently believes that:
   - off_t can be bigger than size_t.
   - only mean kids assign things they do not subsequently inspect.
 
 I don't try to fix the "error" that makes it say:
 
 cc-3970 cc: WARNING File = main.c, Line = 1277
   conversion from pointer to same-sized integral type (potential portability
           problem)
 
     uintptr_t sig = (uintptr_t)arg;
 
 Because really, what can you do about a compiler that claims to be c99
 but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
 is safe?

Patch from Adam Langley.
 
  * I meant getaddrinfo_a, not getaddrinfo_r - fixed
  * Added more checks to the parsing code.
  * It seems you switched an alloca to a malloc, but didn't add any frees

7cb3232ade Add async dns code from Adam Langley, tweaked to build on OSX. Long-term, we may want to switch to libevnet/c-ares, if they ever handle 10k fd situations properly. This one still needs work too, but at least it is small. This code is disabled by default, and not integrated with dns.c.
