Change the name of the second parameter of image writer functions

As of PHP 5.4.0 the second parameter of all image writer functions (except
imagexbm) accepts also a stream resource. Therefore the parameter name
`filename` is inappropriate. We change it to `to` according to what it's
already called in _php_image_output_ctx().

We consider the reflection only related BC break acceptable for a minor version.
