@ fix weird behaviour (in particular with ADODB). (Harald)

# waah, this suxx

  rather than longs.
- Make the IDispatch implementation a bit more generic (and
  fix my mess of pointers).
- Add new com_message_pump() function that acts like an interruptible
  usleep() that processes COM calls/events.
- Add new com_print_typeinfo() function for "decompiling" the typeinfo
  for an interface into PHP script.  This is useful for generating a
  skeleton for use as an event sink.
- Add new com_event_sink() function for sinking events from COM
  objects.  Usage is like this:

<?php

class IEEventSinker {
	var $terminated = false;

	function ProgressChange($progress, $progressmax) {
		echo "Download progress: $progress / $progressmax\n";
	}
	function DocumentComplete(&$dom, $url) {
		echo "Document $url complete\n";
	}
	function OnQuit() {
		echo "Quit!\n";
		$this->terminated = true;
	}
}

$ie = new COM("InternetExplorer.Application");

$sink =& new IEEventSinker();
com_event_sink($ie, $sink, "DWebBrowserEvents2");

$ie->Visible = true;
$ie->Navigate("http://www.php.net");

while(!$sink->terminated) {
	com_message_pump(4000);
}
$ie = null;
?>
