removed unsused ldap module dependency since the module didnt autounload from protected address space.

  verification is requested. Previously it would even return failure if gnutls
  failed to get the server cert even though no verification was asked for.

- Fix my Curl_timeleft() leftover mistake in the gnutls code

  http request and then you'd reuse the handle and replace the Accept: header,
  as then libcurl would send two Accept: headers!

moved info block up before help block so that it can also be displayed before help option; trial to add a version number.

Feb 7 that didn't abort properly on timeouts. These are actually old
problems but now they should be fixed.

added -t switch to make text info of CAs optional;
added -q switch to be really quiet.

out and provides test program that demonstrates that libcurl might not set
error description message for error CURLE_COULDNT_RESOLVE_HOST for Windows
threaded name resolver builds. Fixed now.

  (http://curl.haxx.se/bug/view.cgi?id=1889856): When using the gnutls ssl
  layer, cleaning-up and reinitializing curl ends up with https requests
  failing with "ASN1 parser: Element was not found" errors. Obviously a
  regression added in 7.16.3.

added a switch to display certdata.txt version header.

  them all use the same (hopefully correct) logic to make it less error-prone
  and easier to introduce library-wide where it should be used.

ca-bundle.crt file as outdated and in need for replacement by anyone who wants
to verify modern peers as the one we have is from year 2000!

  use of the "is_in_pipeline" struct field.

  "HttpOnly" feature introduced by Microsoft and apparently also supported by
  Firefox: http://msdn2.microsoft.com/en-us/library/ms533046.aspx . HttpOnly
  is now supported when received from servers in HTTP headers, when written to
  cookie jars and when read from existing cookie jars.

  the SingleRequest one to make pipelining better. It is a bit tricky to keep
  them in the right place, to keep things related to the actual request or to
  the actual connection in the right place.

added curl.res to clean target.

  crash!

pipelining. Broken connection is not restored and we get into infinite
loop. It happens because of wrong is_in_pipeline values.

  (http://curl.haxx.se/bug/view.cgi?id=1879375) which describes how libcurl
  got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
  proxy authentication and the proxy replies with an auth (like NTLM) and then
  closes the connection after that initial informational response.

  libcurl would not properly re-initialize the connection to the proxy and
  continue the auth negotiation like supposed. It does now however, as it will
  now detect if one or more authentication methods were available and asked
  for, and will thus retry the connection and continue from there.

- I made the progress callback get called properly during proxy CONNECT.

did "SESS". Fixed now.
