SPI functions can crash the backend

Description
Creating an invalid array can make spi_fetch_row crash. Example function:
create function crash() returns void language plphp as $$
$a = array('res' => 123);
spi_fetch_row($a);
$$;
Just invoking this function makes PL/php crash. This is because the server tries to dereference a pointer that the user can change. This is stupid. The solution seems to be to change the SPI functions to use PHP "resources".
