Simplify engine interface

[roman-khimov]

Mostly similar to #3001, we have a number of Prm/Res structures that make it harder to used engine and trace things going on. But there are some functional changes here as well and also things that go beyond Prm/Res. Overall we get rid of many pointless conversions.
