Bug description: stream_set_blocking crashes
Description:
------------
When you use stream_socket_client with asynchronous connect
(STREAM_CLIENT_ASYNC_CONNECT), but do not specify STREAM_CLIENT_CONNECT
then stream_set_blocking will crash PHP on Windows XP.
The documentation does NOT tell you to use
STREAM_CLIENT_ASYNC_CONNECT | STREAM_CLIENT_CONNECT.
I think STREAM_CLIENT_ASYNC_CONNECT should implicate
STREAM_CLIENT_CONNECT.
-- Possibility 1 to fix implication ---------
#define STREAM_XPORT_CONNECT 2
#define STREAM_XPORT_CONNECT_ASYNC 18 // instead of 16
#define PHP_STREAM_CLIENT_CONNECT 4
#define PHP_STREAM_CLIENT_ASYNC_CONNECT 6 // instead of 2
-- Possibility 2 to fix "implication" -------
Patch for 5.2.0 source (not CVS).

There are other (somehow) related bugs:

http://bugs.php.net/bug.php?id=28245
Reproduce code:
---------------
<?php
$fp = stream_socket_client("tcp://www.php.net:80", $errno, $errstr,
30, STREAM_CLIENT_ASYNC_CONNECT);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
var_dump(stream_set_blocking($fp, false));
fclose($fp);
}
?>
Expected result:
----------------
If you do not specify STREAM_CLIENT_CONNECT in stream_socket_client the
socket never ever gets connected. Thus, stream_set_blocking should return
FALSE and throw an E_WARNING.
However, as this is a stream function and the stream is still considered
"valid", TRUE might also be all right.
Under Debian Linux (Sarge, Kernel 2.6.8) stream_set_blocking returns TRUE
(which I think is misleading).
Actual result:
--------------
Crashes under Windows XP; returns TRUE on Linux.
