[PHP] RPC request doesn't populate the HTML_RAW_POST_DATA

[Wouter Charle]

Hi, I've setup Shindig using the PHP version and tried to do an RPC request
following the opensocial specifications (with content-type and
authentication set in the request header). I get the following errors:

//------------------------------------------------------
Fatal error: Uncaught exception 'InvalidArgumentException' with message
'Malformed json string' in
/var/www/shindig/php/src/social/servlet/JsonRpcServlet.php on line 134
InvalidArgumentException: Malformed json string in
/var/www/shindig/php/src/social/servlet/JsonRpcServlet.php on line 134
Call Stack:
    0.0005     366444   1. {main}() /var/www/shindig/php/index.php:0
    0.0541    1570652   2. JsonRpcServlet->doPost()
/var/www/shindig/php/index.php:118
//------------------------------------------------------

I went through the code and found that in JsonRpcServlet.php ln 130,
the $requestParam is not set correclty. It should be filled with the
$GLOBALS['HTTP_RAW_POST_DATA']. These globals are set, but contain nothing,
which I assume is wrong.
Is this a bug, or me doing something wrong? Many thanks!
