By setting PROTOPT_NOURLQUERY in the protocol handler struct, the
protocol will get the "query part" of the URL cut off before the data is
handled by the protocol-specific code. This makes libcurl adhere to
RFC3986 section 2.2.

Test 1220 is added to verify a file:// URL with query-part.

Experience has shown that the symbols-in-versions file is very useful to
applications that want to build with a wide range of libcurl versions.
It is however easy to get it wrong and the source gets a bit messy with
all the fixed numerical comparisions.

The point of this script is to provide an easy-to-use macro for libcurl-
using applications to do preprocessor checks for specific libcurl
defines, and yet make the code clearly show what the macro is used for.

Bugfix: https handshake fails using gnutls 3 on windows
http://sourceforge.net/tracker/index.php?func=detail&aid=3441084&group_id=976&atid=100976

New gnutls versions have an error handler that knows about Winsock
errors, which is why gnutls_transport_set_global_errno() was deprecated
and then removed.

This is a correction of commit f5bb3701 (blame me) which meant to
reimplement gnutls_transport_set_global_errno(), which is not necessary.

Regression: commit b998d95b (shipped first in release 7.22.0) made the
condition always equal false that should reset the TIMER_CONNECT timer
and call the Curl_verboseconnect() function.

A regression between 7.22.0 and 7.23.0 -- downloading a file with the
flags -O and -J results in the content being written to stdout if and
only if there was no Content-Disposition header in the http response. If
there is a C-D header with a filename attribute, the output is correctly
written.

prefixing a command with '*' means it is allowed to fail without
aborting the chain actions

Also, check for the session sharing bit instead of comparing pointers

Previously the age counter would be counted individually in each easy
handle that shared SSL sessions!

The progress bar output function would blindly use the terminal width
without bounds checking. When using a very wide terminal that caused a
buffer overflow and segfault.

We now limit the max bar with to 255 columns, and I simplified the code
to avoid an extra snprintf and buffer.

When the user requests PORT with a specific port or port range, the code
could lock up in an endless loop. There's now an extra conditional that
makes sure to special treat the error and try the local address only
once so a second failure will abort the loop correctly.

Bug: http://curl.haxx.se/bug/view.cgi?id=3433968
Reported by: Gokhan Sengun

Just a sign of where the code originally was ripped out from. Now it is
generic "pingpong".

This test is created to verify Rene Bernhardt's patch which makes sure
libcurl properly _not_ deals with Negotiate if not asked to even if the
proxy says it can serve it.

If a proxy offers several Authentication schemes where NTLM and
Negotiate are offered by the proxy and you tell libcurl not to use the
Negotiate scheme then the request never returns when the proxy answers
with its HTTP 407 reply.

It is reproducible by the following steps:

- Use a proxy that offers NTLM and Negotiate ( CURLOPT_PROXY and
CURLOPT_PROXYPORT )

- Tell libcurl NOT to use Negotiate CURL_EASY_SETOPT(CURLOPT_PROXYAUTH,
CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_NTLM )

- Start the request

The call to CURL_EASY_PERFORM never returns. If you switch on debug
logging you can see that libcurl issues a new request As soon as it
received the 407 reply. Instead it should return and set the response
code to 407.

Bug: http://curl.haxx.se/mail/lib-2011-10/0323.html

Move calling of ERR_remove_state(0) a.k.a ERR_remove_thread_state(NULL)
from Curl_ossl_close_all() to Curl_ossl_cleanup().

In this way ERR_remove_state(0) is now only called in libcurl by
curl_global_cleanup(). Previously it would get called by functions
curl_easy_cleanup(), curl_multi_cleanup and potentially each time a
connection was removed from a connection cache leading to premature
destruction of OpenSSL's thread local state hash.

Multi-threaded apps using OpenSSL enabled libcurl should still call
function ERR_remove_state(0) or ERR_remove_thread_state(NULL) at the
very end end of threads that do not call curl_global_cleanup().

Now called 'use_ssl' instead, which better matches the current CURLOPT
name and since the option is used for all pingpong protocols (at least)
it makes sense to not use 'ftp' in the name.

Use gnutls_priority_set_direct() instead of gnutls_protocol_set_priority().

Remove the gnutls_certificate_type_set_priority() use since x509 is the
default certificate type anyway.
