Use Q_GLOBAL_STATIC where K_GLOBAL_STATIC is not needed?

A quick grep says that would break akonadi, grantlee, qca, phonon, qxt and a 
couple of places in KDE that use it already (presumably they don't need the 
features of K_GLOBAL_STATIC that you mentioned). If you (re)move it, we'd 
all just end up copying the macro into our own codebases, so that wouldn't 
achieve much.
