Marc Mutz 110e82f5e9 QString::vasprintf: avoid allocating memory just to parse a number 
Port parse_field_width from constructing a QString and
then calling toInt() on it to use qstrtoull().

Not only do we not allocate memory anymore, we even
don't need to copy the digits out of the format
string - qstrtoull() does it all for us.

In order to preserve behavior with the previous code,
which consumed all digits before performing error
checking on them, we also consume all digits, even if
qstrtoull() would have returned the start of the range
as the end pointer.
