The unit tests weren't running into this problem because the every
setDevice() was preceded by the object being initialized with the exact
same data, so there was never a previous error state. I've only changed
a couple of tests, left the other setDevice() unchanged so we test both
behaviors.

QIODevice represents considreable overhead, even with just QBuffer, for
parsing simple things. Benchmarking showed it was spending 25% of the
parsing time inside one QIODevice function or another. So this commit
accomplishes two things:
1) it increases the buffer size from 9 bytes to up to 256, which should
reduce the number of calls into the QIODevice
2) if the source data is a QByteArray, then use it directly and bypass
the QIODevice, thus increasing performance considerably
