skin engine: Reduce scope of internal wps_data struct

A bunch of public API calls take a wps_data struct argument,
but that's an internal type that doesn't have a direct getter.
Instead the skin engine provides a gui_wps struct as a way
to refer to a particular skin instance. Use that instead of
wps_data in the public API.

 /* Timeout unit expressed in HZ. In WPS, all timeouts are given in seconds
    (possibly with a decimal fraction) but stored as integer values.
    E.g. 2.5 is stored as 25. This means 25 tenth of a second, i.e. 25 units.
