uses the CURLOPT_OPENSOCKETFUNCTION callback to create a unix domain socket
  to a http server.

  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.

  user/password pointers properly even though there might've been a new
  struct/cconnection getting used.

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

  Define HAVE_GSSMIT if <gssapi/{gssapi.h,gssapi_generic.h,gssapi_krb5.h}> are
  available, otherwise define HAVE_GSSHEIMDAL if <gssapi.h> is available.

  Only define GSS_C_NT_HOSTBASED_SERVICE to gss_nt_service_name if
  GSS_C_NT_HOSTBASED_SERVICE isn't declared by the gssapi headers. This should
  avoid breakage in case we wrongly recognize Heimdal as MIT again.

  message when libcurl doesn't get a 220 back immediately on connect, I now
  changed it to be more specific on what the problem is. Also worth noticing:
  while the bug report contains an example where the response is:

    421 There are too many connected users, please try again later

  we cannot assume that the error message will always be this readable nor
  that it fits within a particular boundary etc.

  GET simply because previously when you set CURLOPT_NOBODY to TRUE first and
  then FALSE you'd end up in a broken state where a HTTP request would do a
  HEAD by still act a lot like for a GET and hang waiting for the content etc.

$capath is known to configure, so it can be defined in config.h instead.

- Fixed detection of previously installed curl-ca-bundle.crt

SFTP quote command reported by Vincent Le Normand, but left it disabled.

- Added macros for curl_share_setopt and curl_multi_setopt to check at least
  the correct number of arguments.

reproduce the --ftp-create-dirs problem reported by Brian Ulm, but that
seems to need a call curl_easy_reset() which this test case doesn't do.

  CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
  handle and uploaded another file to another directory that needed to be
  created, the second upload would fail. Another case of a state variable that
  wasn't properly reset between requests.

- I rewrote the 100-continue code to use a single state variable instead of
  the previous two ones. I think it made the logic somewhat clearer.
