VCL-1106 - make PHP code compatible with PHP 7

utils.php: modified xmlrpccall xmlrpcgetaffiliations: $HTTP_RAW_POST_DATA is deprecated in php 7 - removed global reference to $HTTP_RAW_POST_DATA; now get contents of php://input into variable and pass that variable to xmlrpc_server_call_method instead of $HTTP_RAW_POST_DATA
