By the way, re: https://bugreports.qt.io/browse/QTBUG-47629

We should use 64-bit in QJsonPrivate too. Specifically, because of the way that 
the internal binary JSON format stores values, we steal 5 bits from all 
possible lengths, causing the maximum JSON data to be limited to 128 MB. 
Apparently, it's not that difficult to hit that limit today.

Given that we have QJsonDocument::fromRawData / fromBinaryData as public API, 
we need to keep compatibility with version 1 input for at least a couple more 
years, so if we do this change, we either need to keep both codepaths 
available or we need to reindex version 1 data.

Any volunteers to look into this?
