This reverts commit ac0184d608. That
commit added the use of qHash in qt_safe_ftok, which made ftok even more
unsafe than previously. Since the algorithm in qHash can change across
Qt versions, we need a stable algorithm instead.
[ChangeLog][Important Behavior Changes] Reverted a change that caused Qt
5.6 through 5.8 not to connect to QSystemSemaphore and QSharedMemory
created by running applications using Qt earlier than
5.6. Unfortunately, this means that Qt 5.9 will not connect to 5.6-5.8.

We should carry this in all 5.5.x and 5.6.x releases, to make sure
everyone gets the message. But for this release, we need to note the
changes from what was announced for 5.5.0:
Clang 3.2 cannot compile std::atomic properly, so it will not be
supported. That means the minimum XCode version we'll require will be
5.1, which fortunately does not raise the minimum OS X version that can
compile Qt. See http://llvm.org/bugs/show_bug.cgi?id=12670 for more
information.
ICC 14.x and 15.x on Windows miscompiles pointer-to-members across DLL
boundaries, so signal-slot connections fail. See QTBUG-40281.

The -fPIE option is now accepted when using GCC 4, which means it
is available for backward compatibility for clients using
CMake 2.8.11 or older which makes use of the
POSITION_INDEPENDENT_CODE feature.
Conditionally use that feature for old versions of cmake with
GCC 4. Restore the tests for those versions, and clarify the
situation in the ChangeLog.

Prior to Qt 5.4.2 (commit 36d6eb721e), we
allowed it, but now we need to enforce that it is not used. Note that
-fPIE does define __PIC__, so we need this to catch the use of -fPIE.
[ChangeLog][Important Behavior Changes] On x86 and x86-64 systems with
ELF binaries (especially Linux), due to a new optimization in GCC 5.x in
combination with a recent version of GNU binutils, compiling Qt
applications with -fPIE is no longer enough. Applications now need to be
compiled with the -fPIC option if Qt's option "reduce relocations" is
active. Note that Clang is known to generate incompatible code even with
-fPIC if the -flto option is active.

On modern ARM CPUs there is no speed difference between

qreal to avoid rounding and precision issues. Like this
we also get much better compatibility with our desktop
OSes.
This is not binary compatible on ARM, but the old behavior
can be restored by passing -qreal float to configure.

I don't think I ever worked on a project of non-trivial
size that didn't at some point add a QSignalBlocker.
This commit adds code, tests and documentation. Later
commits will convert naked blockSignals() calls to use
QSignalBlocker.
The implementation is purely inline to avoid the heavy
overhead of cross-dll function calls for this miniscule
task. This should not be a problem because QSignalBlocker
only uses public API and a pattern that we anyway need
to keep working until Qt 6, at least, so even changing
the implementation later will be no problem as the old
implementation lurking in non-recompiled code will be
acceptable, too.
This implementation is an evolution from KDTools'
KDSignalBlocker, with the following changes:
- Implements unblock() and reblock()
- Uses the return value of blockSignals() instead of a
separate signalsBlocked() call.

This patch allows to set which logical index the tree is in.
Before the tree always displayed data from the logical index 0,

QDateTime::fromString(str, Qt::TextDate) and
