Add QGenericArray to simplify operations. This class can be shared by other tool classes. If there is nothing else to share it, we can move the code onto qvector.h. The one candidate is QList. All tests pass and valgrind is good. Change-Id: Ieaa80709caf5f50520aa97312ab726396f5475eb Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
