QHostAddress is one of the few classes in Qt which is pimpl'd but not
implictly shared, making it suprisingly expensive to copy around, return
by value and so on. Being pimpl'd it is also still lacking a move
constructor, like most of such types in Qt.
Remove a bit of the surprise factor and make it implictly shared. In
practice this means making it eagerly parse host addresses from strings.
Since it was entirely implemented out of line, replacing it with a
implictly shared implementation is binary compatible.
[ChangeLog][QtNetwork][QHostAddress] QHostAddress is now implicitly
shared.

On ABIs where quint64 is aligned on 8-byte boundaries (such 32-bit
Windows and all 64-bit systems), there was a padding hole of 4 bytes
between QHostAddressPrivate::a and the anonymous union. If we move the
member to after the union, there is no hole anymore.
That operation causes the tail padding to grow from 3 to 7 bytes. Since
we also don't need full 32 bits for the protocol, we can shrink the
structure by 8 bytes on those architectures and by 4 bytes on 32-bit
Unix systems.

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.

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.

Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

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.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

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.

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.

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

Most of the QIODevice functions already have a locally cached
"sequential" flag. Make the rest of them follow this strategy.
This eliminates the need to use private caching members.

These hooks only worked reliably with LD_PRELOAD on Linux/GCC, on other
platforms they depended on what exactly the compiler optimizer is doing
as well as some nasty assembler rewriting to actually access them. The
new system uses a simple array of function pointers that can be set to
custom hooks by tools that need this (based on ideas from Andre Poenitz).
This also covers qt_startup_hook (similar problem), and the Qt version
number that Andre had asked for.
