Marc Mutz bbb440bab2 QJsonValue: fix use-after-free in assignment operator 
The assignment operator of a String QJsonValue that holds
the only remaining reference to the QString::Data block
was freeing the block before obtaining its own reference,
leading to a use-after-free in the case where *this was
passed as 'other' (self-assignment).

Fixed by reformulating the assignment operator in terms
of the copy ctor, using the copy-swap idiom, with the
twist that QJsonValue doesn't, yet, have a swap member
function, so we use three per-member qSwap()s.
