Turns out our custom HashX class was doing some funny things when a
HashX had a \0 byte. Likely QByteArray isn't really intended to be
inherited from. Rather than investigate what was going on -- I just
decided it's sufficient to do: using HashX = QByteArray and be done with
it.
Now our utxo set is working correctly.
We still need to figure out how to store everything.. but this is
progress.
The PreProcessedBlock is intended to be a somewhat munged/mogrified form
of a CBlock which is somewhat ready for a db insert.
This data will get passed onto the Controller thread which will set
everything up to commit the SH history, header, etc to the db.
Did some initial testing and it's pretty fast and also.. I think it's
correct (as in I'm collating the data correctly).
TODO: Some more testing.
