Move qVersion() from qglobal.h to qlibraryinfo.h
Since qVersion() might be called also from C code, disable the parts of
qlibraryinfo.h that are relevant only for C++ code if __cplusplus is not
defined.
[ChangeLog][Potentially Source-Incompatible Changes] qVersion() is
moved from qglobal.h to qlibraryinfo.h, '#include <QtCore/QLibraryInfo>'
needs to be added where it's used.
