uvw version 3.0 has incompatible changes to API

[pemensik]

I have attempted to update my uvw package to new version 3.0, but it contains quite a lot of incompatible changes. There is quite a lot of renamed structures and some changes in function prototypes as well.

I have create issue requesting some backward compatibility: skypjack/uvw#285

The bad thing is current latest version does not offer anything to be able to compile with both 2.x or 3.x version. It seems to me some improvement should be done on side of uvw first.
