This check, which was only done once, was wrong:
const int bytes_per_line = ((width * depth + 31) >> 5) << 2;
// sanity check for potential overflows
if (std::numeric_limits<int>::max()/depth < width
If width*height overflows, then it's already UB and checking afterwards
with a division is pointless and slow.
The other instances weren't properly guarding against overflows.

QImage's operator>>(QDataStream&) did not set an error mode on the
stream on read failures. That would break QDataStream transactions.
Since the current QImage serialization cannot differentiate between
truncated and corrupted data, we set the ReadPastEnd error as expected
by the transaction system.
Also specify the expected file format on decoding QImage from stream,
to avoid all the format handlers' canRead() being invoked. This is
necessary since some of them may call ungetChar(), which fails when
the stream is in a transaction.
Also add testing of this feature to the QDataStram transaction
autotest. That required a slight rewrite of the fake sequential
QIODevice subclass. The previous implementation had incorrect
behavior of peek(), which is required by QImage decoders.
