Peter Hutterer 42dc91e32a include: let BitIsOn() return a boolean value. ...

Simply returning the mask bit breaks checks like
    BitIsOn(mask, 0) != BitIsOn(mask, 1);
as used in 048e93593e.

The naming of this macro suggests that it should return boolean values
anyway. This patch also adds a few simple tests for these macros to make
sure they don't accidentally break in the future.
