Unify all mid() functions in QtBase.
Up to now, Qt had at least 3 different implementations of the mid(). Only QString::mid implementation was not crashing on edge cases and was protected against overflows, therefore I picked that one as the base implementation, even if it has weird semantics for an invalid input. As a side effect QVector::mid was slightly optimized to not detach in all cases (which follows current QList behavior). Documentation of QVector::mid and QList::mid was updated to not mention "copy of data" which could suggest that the mid() result is detached. QStringRef::mid was fixed and now it follows general Qt behavior, by returning a null value for a null input.
