1a161c8ede QDateTimePrivate: merge the time spec, DST status and validity flags
Storing them in a single byte is the first step towards the Short
QDateTime Optimization.

The bump in the "private version" by 10 is to accommodate possible
changes in the Qt 5.7 branch.

Also, bump the TypeInformationVersion field in qtHookData, to notify
the Qt Creator developers that the offset of QFilePrivate::fileName
was changed and dumpers should be adapted.

41e59ae0fa QIODevice: make the read/write chunk sizes configurable
By default, the read chunk size is QIODEVICE_BUFFERSIZE and the write
chunk size is 0 (which means that we don't use the internal write buffer).
Derived classes may override these values to define the size of
QIODevice's write buffer or to optimize the read buffer use.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

1c0494e63b QIODevice: add infrastructure for multistreaming
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
changed and dumpers should be adapted.

[ChangeLog][QtCore] Added multistreaming to QIODevice.

7d257aab81 QIODevice: handle incomplete reads
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.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

[ChangeLog][QtCore] Added QIODevice's startTransaction(),
commitTransaction(), rollbackTransaction(), isTransactionStarted()
functions to support the read transactions.

7b0e771ad7 Add a qtHookData field for Qt Creator's data display
Qt Creator needs to be able to determine structure sizes and data
member offsets for certain private types even in the absence of debug
information.

It is sufficient to keep and test the actual data sets on the Qt Creator
side, as long library provides a hint which data set is needed.
So far, HookDataVersion was meant to be used for that purpose. To
make it more explicit, this patch introduce a TypeInformationVersion
field in qtHookData.

83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

497f0af1f7 Add some tools specific consistency tests
This upstreams parts of Qt Creator's tst_offset test to serve as
an early warning system by testing private implementation details
that are used in Qt Creator's data structure "pretty printing"
facility.

While the tested implementation details can be changed without
breaking binary or source compatibility, downstream tools like
Qt Creator depend on them.

If this test breaks, you are kindly asked to coordinate with the
downstream stakeholders to avoid tool breakage.
