- Tom Mueller correctly reported in bug report #2870221

(http://curl.haxx.se/bug/view.cgi?id=2870221) that libcurl returned an
  incorrect return code from the internal trynextip() function which caused
  him grief. This is a regression that was introduced in 7.19.1 and I find it
  strange it hasn't hit us harder, but I won't persue into figuring out
  exactly why.

   SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger.  The
   patch doesn't do a setsockopt if SO_SNDBUF is already greater than
