qglobal.h unnecessarily includes <assert.h>

It took me a while to find out what pollutes my whole project with the definition of 'assert' (which I wanted to be undefined and produce a compilation error so I could easily fix all incorrect uses of 'assert'). Turns out it's qglobal.h that does it, and it doesn't even use the 'assert' macro, at least not that I could find.

I would love to see this include removed and have a cleaner global scope.
