We have to make sure that the plugins to be tested are located inside
the virtual sandbox / relative to the application binary. Launching via
winrtrunner, a test can find those plugins then. It is not possible to
those via TESTDATA and extract them to temp, as LoadPackagedLibrary only
loads inside the sandbox.
Unfortunately this also implies that running those tests inside Visual
Studio will fail, as Visual Studio copies the virtual sandbox to another
location missing the plugins. For automated testing this should not
matter though.

Some sequential devices allow data to be partitioned into several
channels that have the property of independently sequenced delivery.
Supporting such devices uniformly requires a unified API which provides
the user with a uniform concept of multistreaming.
This patch is based on QProcess's multiplexing model and introduces
the following features:
- ability to get the number of channels;
- multiple internal read/write buffers;
- channel selection functions;
- notification signals on channel activity.
To keep the source code compatible with single-channel implementations,
introduce a private class that references the current read buffer and
hides multistreaming internals from the user.
Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was

Introduce a transaction mechanism that gives the ability to read the
data atomically. Current implementation supports transactions for both
types of devices. For sequential devices, it records the whole input
stream during transaction. For random-access devices, device position
is saved when transaction starts. If an error occurs, the application
may be able to recover the input stream by rolling back to the start
point.
Also, QIODevice::peek() was rewritten to make use of transactions
internally. The replacement of QIODevicePrivateLinearBuffer by
QRingBuffer is closely entangled with that, which makes it unfeasible
to do separately.

ignorant of its DST, while a .toLocalTime() one knows its DST.
