Reference counting the credential handle should avoid that such a
handle is freed while it is still required for connection shutdown

SSL didn't work on older cats if built on a newer cat with weak-linking
turned on to support the older cat

Bug: http://curl.haxx.se/bug/view.cgi?id=3561305

Patch by: Marcel Raad

Each certificate section of the input certdata.txt file has a trust
section following it with details.

This script failed to detect the start of the trust for at least one
cert[*], which made the script continue pass that section into the next
one where it found an 'untrusted' marker and as a result that certficate
was not included in the output.

[*] = "Hellenic Academic and Research Institutions RootCA 2011"

I accidentally broke functionality for versions of OS X prior to Mountain
Lion in the previous commit. This commit fixes the problems.

If we need an NTLM connection and one already exists, always choose that
one.

In Mountain Lion, Apple added TLS 1.1 and 1.2, and deprecated a number
of SecureTransport functions, some of which we were using. We now check
to see if the replacement functions are present, and if so, we use them
instead.  The old functions are still present for users of older
cats. Also fixed a build warning that started to appear under Mountain
Lion

Commit b91d29a28e170c16d65d956db79f2cd3a82372d2 introduces a bug and breaks Curl_closesocket function. sock_accepted flag for the second socket should be tagged as TRUE before the sockopt callback is called because in case the callback returns an error, Curl_closesocket function is going to call the - fclosesocket - callback for the accept()ed socket

For active FTP connections, applications may need setting the sockopt after accept() call returns successful. This fix gives a call to the callback registered with CURL_SOCKOPTFUNCTION option. Also a new sock type - CURLSOCKTYPE_ACCEPT - is added. This type is to be passed to application callbacks with - purpose - parameter. Applications may use this parameter to distinguish between socket types.

Commit e351972b brought in the ssh agent support but some uses of
the libssh2 agent API was done unconditionally which wasn't good enough
since that API hasn't always been present.

CURLSSH_AUTH_AGENT is a new auth type for SSH

Fixed this (harmless) clang-analyzer warning. Also fixed the source
indentation level.

By reading the ->head pointer and using that instead of the ->size
number to figure out if there's a list remaining we avoid the (false
positive) clang-analyzer warning that we might dereference of a null
pointer.

I suspect this is a regression introduced in commit 207cf150, included
since 7.24.0.

Avoid showing '(nil)' as hostname in verbose output by making sure the
hostname fixup function is called early enough to set the pointers that
are used for this. The name data is set again for each request even for
re-used connections to handle multiple hostnames over the same
connection (like with proxy) or that the casing etc of the host name is
changed between requests (which has proven to be important at least once
in the past).

Test1011 was modified to use a redirect with a re-used a connection
since it then showed the bug and now lo longer does. There's currently
no easy way to have the test suite detect 'nil' texts in verbose ouputs
so no tests will detect if this problem gets reintroduced.

Ensure that the copy of the CURLOPT_INTERFACE string is freed if we
decide we can reuse an existing connection.

This is the same fix applied for the conditional code that uses select()
that was already done for the poll specific code in commit
b61e8b81.

We found a problem with ftp transfer using libcurl (7.23 and 7.25)
inside an application which is receiving unix signals (SIGUSR1,
SIGUSR2...) almost continuously. (Linux 2.4, PowerPC, HAVE_POLL_FINE
defined).

Curl_socket_check() uses poll() to wait for the socket, and retries it
when a signal is received (EINTR). However, if a signal is received and
it also happens that the timeout has been reached, Curl_socket_check()
returns -1 instead of 0 (indicating an error instead of a timeout).

In our case, the result is an aborted connection even before the ftp
banner is received from the server, and a return value of
CURLE_OUT_OF_MEMORY from curl_easy_perform() (Curl_pp_multi_statemach(),
in pingpong.c, actually returns OOM if Curl_socket_check() fails :-)
Funny to debug on a system on which OOM is a possible cause).

Due to WSAPoll bugs, libcurl does not work as intended. When the cURL
library is used to setup a connection to an incorrect port, normally the
result is CURLE_COULDNT_CONNECT, /* 7 */, but due to the bug in WSAPoll,
the result now is CURLE_OPERATION_TIMEDOUT, /* 28 - the timeout time was
reached */.

On August 1, Jan Koen Annot opened a case for this to Microsoft Premier
Online (https://premier.microsoft.com/).  The support engineer handling
the case wrote that the case description is quite clear.  He will try to
reproduce the issue and then proceed with troubleshooting it.

Synced the output to the same short form as we now use for
Windows SSL (WinSSL).

Previously the curl_multi interface would freeze if darwinssl was
enabled and at least one of the handles tried to connect to a Web site
using HTTPS. Removed the "wouldblock" state darwinssl was using because
I figured out a solution for our "would block but in which direction?"
dilemma.

DragonFly uses milliseconds, while our API and Linux use full seconds.

In many states the easy_conn pointer is referenced and just assumed to
be working. This is an added extra check since analyzing indicates
there's a risk we can end up in these states with a NULL pointer there.
