A simple 16k file can produce deep enough recursion in Qt to cause stack overflow. So prevent that. I tested 4096 recursions just fine on my Linux system (8 MB stack), but decided 1024 was sufficient, as this code will also be run on embedded systems that could have smaller stacks. [ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at most 1024 nested maps, arrays, and tags to prevent stack overflows. This should be sufficient for most uses of CBOR. An API to limit further or to relax the limit will be provided in 5.15. Meanwhile, if decoding more is required, QCborStreamReader can be used (note that each level of map and array allocates memory).
