The matatype should not keep manually maintained list of stream
operators. The patch adds automatic detection for all builtin types
so load and save functions pick the right delegate automatically.
This change exposed some existing anomalies:
- char is enforced to be signed while it seems that just calling
the operator directly does not have that feature.
- [unsigned] long type is always upgraded to [unsigned] long long
- QCborSimpleType doesn't have the data stream operators while
metatype is able to stream it through casting
