Made --interface tests less restrictive on host address.

that starting with Automake 1.8, aclocal will warn about all underquoted calls
to AC_DEFUN due to the fact that in a single aclocal run it might include more
than once all .m4 files which it finds available, this includes .m4 files from
other software packages.

If the first argument to AC_DEFUN is underquoted and the same macro is included
more than once, successive inclusions after the first one will expand the macro
instead of assuming it is the same as the first one included.

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.

libtest code.

when function clock_gettime() is available and the monotonic timer is
also available. Otherwise, in some cases, librt or libposix4 could be used
for linking even when finally not using the clock_gettime() function due
to lack of the monotonic clock.

This also implies the removal of the winmm.lib dependency for WIN32.
