doc: Added \relates command to some function qdoc comments

When a documented function is global, it must be related
to a namespace or class, or its documentation won't be
included anywhere.

When a documented function is a class member, the function
signature in the \fn command must include the class name
qualifier, e.g. QImage::isValid(), not just isValid()
