This is the same fix applied for the conditional code that uses select()
that was already done for the poll specific code in commit
b61e8b81f5038.

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.

When figuring out if the data stream needs to be rewound when the
request is to be resent, we must not access the HTTP struct unless the
protocol used is indeed HTTP...

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.

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.

Spotted by clang-analyzer. The return code was never checked, just

va_end() needs to be used after va_start() and we don't normally use
Curl_ prefixes for purely static functions.

This avoids false positives from clang's scan-build.

A HEAD response has no body length and gets the headers like the
corresponding GET would so it should not get closed after the response
based on the same rules. This mistake caused connections that did HEAD
to get closed too often without a valid reason.

The function https_getsock was only implemented properly when USE_SSLEAY
or USE_GNUTLS is defined, but it is also necessary for USE_SCHANNEL.
The problem occurs when Curl_read_plain or Curl_write_plain returns
CURLE_AGAIN. In that case CURL_OK is returned to the multi-interface an
the used socket is set to state CURL_POLL_REMOVE and the easy-state is
set to CURLM_STATE_PROTOCONNECT. This is fine, because later the socket
should be set to CURL_POLL_IN or CURL_POLL_OUT via multi_getsock. That's
where https_getsock is called and doesn't return any sockets.

Re-wrote Curl_darwinssl_random() to not use arc4random_buf() because the
function is not available prior to iOS 4.3 and OS X 10.7.

The code was printing a warning when SNI was set up successfully. Oops.
Printing the cipher number in verbose mode was something only TLS/SSL
programmers might understand, so I had it print the name of the cipher,
just like in the OpenSSL code. That'll be at least a little bit easier
to understand. The SecureTransport API doesn't have a method of getting
a string from a cipher like OpenSSL does, so I had to generate the
strings manually.

Reduce the number of #ifdef UNICODE directives used in source files.

When doing CONNECT requests, libcurl must make sure the connection is
alive as much as possible. NTLM requires it and it is generally good for
other cases as well.
NTLM over CONNECT requests has been broken since this regression I
introduced in my CONNECT cleanup commits that started with 41b02378342,
included since 7.25.0.
