Made --interface tests less restrictive on host address.

added to DISABLED.

uploads with -C - didn't resume properly, but the tests pass.

  fix for it. It occured when you did a FTP transfer using
  CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
  switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
  cleared properly.  Scott's test case is now known as test 539 and it
  verifies the fix.

response codes. Previously libcurl would hang on such occurances. I added
test case 1033 to verify.

  (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487567) pointing out that
  libcurl used Content-Range: instead of Range when doing a range request with
  --head (CURLOPT_NOBODY). This is now fixed and test case 1032 was added to
  verify.

  All boolean options (such as -O, -I, -v etc), both short and long versions,
  now always switch on/enable the option named. Using the same option multiple
  times thus make no difference. To switch off one of those options, you need
  to use the long version of the option and type --no-OPTION. Like to disable
  verbose mode you use --no-verbose!

- Added --remote-name-all to curl, which if used changes the default for all
  given URLs to be dealt with as if -O is used. So if you want to disable that
  for a specific URL after --remote-name-all has been used, you muse use -o -
  or --no-remote-name.

  curl_easy_getinfo. It returns a pointer to a string with the most recently
  used IP address. Modified test case 500 to also verify this feature. The
  implementing of this feature was sponsored by Lenny Rachitsky at NeuStar.

  how the HTTP redirect following code didn't properly follow to a new URL if
  the new url was but a query string such as "Location: ?moo=foo". Test case
  1031 was added to verify this fix.

  when using CURL_AUTH_ANY" (http://curl.haxx.se/bug/view.cgi?id=1945240).
  The problem was that when libcurl rewound a stream meant for upload when it
  would prepare for a second request, it could accidentally continue the
  sending of the rewound data on the first request instead of on the second.
  Ben also provided test case 1030 that verifies this fix.

  redirections and thus cannot use CURLOPT_FOLLOWLOCATION easily, we now
  introduce the new CURLINFO_REDIRECT_URL option that lets applications
  extract the URL libcurl would've redirected to if it had been told to. This
  then enables the application to continue to that URL as it thinks is
  suitable, without having to re-implement the magic of creating the new URL
  from the Location: header etc. Test 1029 verifies it.

Reintroduce, for test # 1001, the <postcheck> small delay. The delay is
needed even with the accelerated writing of server input and response
request files in test harness sws server.

problem.

by Ben Combee where libcurl would send the wrong cookie to a redirected
server.  libcurl was doing the right thing in this test case.
