Bug description:file_get_contents POST request sends additional line breaks

Description:
------------
When doing HTTP POST requests using file_get_contents and an appropriate
stream context (http method = POST, content = ...) two additional line
breaks ("\r\n\r\n") are added below the POST message body. This is wrong
according to the default encoding "application/x-www-form-urlencoded" and
has been seen to upset some webservers (content length is incorrect).

Run the testscript and check the traffic using tcpdump/tcpflow or
wireshark. You'll see additional lines at the end of the message body.

Attached is a very simple patch against http_fopen_wrapper.c from PHP 5.3.5
source which removes sending "\r\n\r\n".

Test script:
---------------
<?php

$ctx = stream_context_create(array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-Type: application/x-www-form-urlencoded',
        'content' => 'a=1&b=2',
    )
));

$response = file_get_contents('http://www.php.net/', false, $ctx);
echo $response;
