Explain what "junk" means in tst_QDataStream::status_QBitArray_data()

Browse Source 
It means the data contains bits outside the [0, size()[ range.

Found while debugging why these data rows fail in the 5.15 cherry-pick
of 78f8dfc5427457783ceef7d85885cddbec035ebe.

Amends the start of the public history.

Pick-to: 6.10 6.9 6.8 6.5 5.15
