Review request for Solid and Martin Gräßlin.

Description
-------

This ports the XRandrBacklight class to XCB.

The code is adapted from xbacklight, drops the legacy backlight stuff, whatever that is.

It still uses XSync since xcb_aux_sync yields a linker error here (what did I overlook?). Pretty ugly C stuff (fre...), suggestions on how to improve the code look (nullptr, C++ style casts, etc) welcome.

Testing
-------

My hopes were that it would give us a more precise backlight handling but I get a range of 0..10 nonetheless. Other than that seems to work exactly like it did before.


Thanks,

Kai Uwe Broulik
