b226e99c71 Fix DESTDIR handling on Windows for Qt modules != qtbase
On the CI system, we build qtbase with CMAKE_INSTALL_PREFIX set to a
path without a drive letter to support DESTDIR when installing.
Other Qt modules are built without CMAKE_INSTALL_PREFIX set. The
Qt6BuildInternals package provides a default value.

Since commit e6527e2f73 this default
prefix is calculated from the current installation location. This
default prefix however has a drive letter, breaking DESTDIR support.

Broken DESTDIR support in this case means for Android that file(INSTALL)
can properly install but stripping will silently fail.

We now compare the "real path" of the original prefix from qtbase and
the calculated prefix. When they're equal, we use the original
CMAKE_INSTALL_PREFIX.

access the parent-child hierarchy of the source model requires modifying

4d838dae5a CMake: Generate better Xcode iOS projects
Add an iOS specific plist file like we do for macOS.

If the user hasn't specified a bundle identifier or a development
team id, do what qmake does and query the Xcode preferences file to
pre-populate those if possible.

This allows running

 cmake -GXcode ./foo

on a Qt example project and building it with xcodebuild on the
command line without having to go through the IDE to set a development
team id or modifying the example project to add a product
bundle identifier.

Note that the change assumes that the development team id has been
previously set / configured via Xcode. If no such id is found, then
the value will not be set and the user will still have to specify it
either in the project file or via the Xcode UI after the project
has been generated.

b25eb6e0bd CMake: Introduce zlib find script to work around hardcoded iOS SDK
Xcode allows building a project targeting either the device or
simulator sysroot in one single build dir, but for the sysroot
switching to work there should be no linker or compiler flags
referencing absolute paths of a specific sysroot.

During CMake configuration of a project targeting iOS, all found
system libraries will be within one single sysroot, either the device
one or the simulator one, whichever one was passed to
CMAKE_OSX_SYSROOT. CMake will then generate the Xcode project
and pass those absolute paths, which makes sysroot switching within
Xcode not work.

To avoid that, the CMake documentation recommends passing linker and
framework flags of the form '-lfoo' and '-framework bar' instead of
absolute paths. Xcode then takes care of setting the correct framework
search path.

Zlib is one of the libraries found in the iOS sysroot and thus passed
as absolute path.
To avoid that, create a new FindWrapZLIB find script. The target it
creates will pass the absolute path to the library on non Apple
platforms and an -lz linker flag on Apple platforms (macOS and iOS).

To avoid issues with target global promotion when system PNG package
is found, ensure that a found ZLIB::ZLIB target is promoted to global
manually in src/gui/configure.cmake.

has been changed: if the variable is set but empty, it is interpreted
now as if it had not been set and the hash salting functionality is
enabled.

a794c5e287 Unicode: fix the extended grapheme cluster algorithm
UAX #29 in Unicode 11 changed the EGC algorithm to its current form.
Although Qt has upgraded the Unicode tables all the way up to
Unicode 13, the algorithm has never been adapted; in other words,
it has been working by chance for years. Luckily, MOST
of the cases were dealt with correctly, but emoji handling
actually manages to break it.

This commit:

* Adds parsing of emoji-data.txt into the unicode table generator.
  That is necessary to extract the Extended_Pictographic property,
  which is used by the EGC algorithm.

* Regenerates the tables.

* Removes some obsoleted grapheme cluster break properties, and
  adds the ones added in the meanwhile.

* Rewrites the EGC algorithm according to Unicode 13. This is
  done by simplifying a lot the lookup table. Some rules (GB11,
  GB12, GB13) can't be done by the table alone so some hand-rolled
  code is necessary in that case.

* Thanks to these fixes, the complete upstream GraphemeBreakTest
  now passes. Remove the "edited" version that ignored some rows
  (because they were failing).

cf42a0fe5e Remove lazy binding evaluation
Too much of the existing code in Qt requires eager evaluation without
large scale modifications. Combined with the fact that supporting both
eager and lazy evaluation has a high maintenance burden, keeping lazy
evaluation, at least in its current state, is not worth it.

This does not diminish other benefits of the new property system, which
include
- a C++ API to setup and modify bindings and
- faster execution compared to QML's existing bindings and the ability
  to use them without having a QML engine.

We do no longer benefit from doing less work thanks to laziness. A later
commit will introduce grouping support to recapture some of this
benefit.

[ChangeLog][Import Behavior Change][QProperty] QProperty uses always
eager evaluation now when a dependency in a binding changes.

f4417bf7e8 Check whether CMake was built with zstd support
CMake 3.18 introduced the file(ARCHIVE_CREATE) API that we use with
COMPRESSION Zstd for compressing corelib's mimedatabase.

It's possible to build CMake without proper zstd support, and we have
encountered such builds in the wild where the file(ARCHIVE_CREATE) call
crashes.

Add a configure test to determine whether CMake properly supports the
Zstd compression method.

5656a60dd0 QList::(const_)iterator: protect element_type on GCC < 11
GCC 10 in C++20 mode will still try to use
std::indirectly_readable_traits on QList iterators, and since it
does not have the fixes for LWG 3346 / 3541, it will fail to build:

    /usr/include/c++/10/bits/iterator_concepts.h: In substitution of ‘template<class _Tp> using __iter_value_t = typename std::__detail::__iter_traits_impl<_Tp, std::indirectly_readable_traits<_Iter> >::type::value_type [with _Tp = QList<std::pair<int, int> >::const_iterator]’:

So hide element_type as well.

The CI didn't catch this because the CI doesn't build in C++20 mode.

b322bfcc14 QString: add missing char8_t* constructor / fromUtf8 overloads
Currently we support:

  QString s = QString::fromUtf(u8"foo", 3);

But we don't support

  QString s = QString::fromUtf8(u8"foo");
  QString s(u8"foo");

There's no reason not to have these two functions. Guess what,
we've actually got code _in Qt_ that tries to build a QString out of
a char8_t; that code stops compiling under C++20 (which is supported,
but not CI-tested at the moment, it seems).

Re-add the missing constructor and fromUtf8 overloads.

[ChangeLog][QtCore][QString] Added a constructor and a fromUtf8()
overload taking a `const char8_t *` argument.

QML. Switching this on has no runtime overhead. For interface libraries
we cannot generate any metatypes, though.

930e59b798 QTest: add helper methods to test bindable properties
This patch adds helper methods to test bindable properties in the QTest
lib. These methods can be useful in many Qt modules, so we decided to
have them in qtbase.
For now they are in the private header, because we are not sure that
they can be useful for the end users.
