provide analogue functionality to CURLINFO_HEADER_OUT

[rcanavan]

Sometimes, it's necessary to inspect the actual request including all header that have been sent. The PHP curl extension implements this via the CURLINFO_HEADER_OUT option. The patch below provides similar functionality for ext-http.

I just pushed http\Client::setDebug() in 1ac722a which should give you the necessary facility to implement your needs.

Thank you.

Example:

<?php
$c = new http\Client;
$c->enqueue(new http\Client\Request("GET", "https://m6w6.name"));

$c->setDebug(function(http\Client $c, http\Client\Request $r, int $type, string $data) {
    if ($type & http\Client::DEBUG_HEADER) {
        echo $data;
    }
});

$c->send();' 

Output:

GET / HTTP/1.1
Host: m6w6.name
User-Agent: PECL_HTTP/3.1.0dev PHP/7.1.0-dev libcurl/7.49.1

At first glimpse 1ac722a actually seems to satisfy our needs. Thanks very much!
