8780fbb2eb Build Qt (and client apps using it) with /permissive-
*Not* using /permissive- exposes Qt and client apps to interesting
bugs and/or build failures, (e.g. QTBUG-87225, or
19b5520abf). We demand strict
conformance by any other compiler, it's time to demand it from
MSVC too.

The Windows headers themselves are clean starting from the
Windows Fall Creators SDK (10.0.16299.0), and moreover Qt 6 will
drop WinRT; therefore, the comment in the mkspecs does not apply
any more.

Since /permissive- implies /Zc:referenceBinding, drop that
option. The other implied options are set on MSVC < 2017,
but I leave them in to avoid tinkering with the fragile lists
of C/C++ flags.

Rename the CMake internal helper function to better describe
what it does.

5c352f47b9 Add doc target for qmake
qmake currently doesn't have a doc target in CMake. In qmake builds, the
doc target is in qtbase/ (not in qtbase/qmake). This patch mimics the
mechanic used in QDoc, and adds this as a special case (as the project
file doesn't contain the doc target).

4fbb2f66d6 Add a QMetaSequence interface
This is in line with QMetaType and will be used to implement a mutable
QSequentialIterable. Later on, a QMetaAssociation will be added as
well, to implement a mutable QAssociativeIterable.

The code here represents the minimal set of functionality needed to have
a practical sequential container. The functionality is not completely
orthogonal. In particular, the index based operations could be
implemented in terms of iterator-based operations.

ed8acbeb7c Automatically register data/debug stream operations in QMetaType
And remove the old manual registration code for those operators.

Add some special handling for long/ulong, as these types could be
streamed as a QVariant so far, but are not directly streamable
through QDataStream.

[ChangeLog][QtCore][QMetaType] The QMetaType::registerStreamOperators()
and QMetaType::registerDebugStreamOperator() methods have been
removed. The streaming operators for a type are now automatically
registered together with the type registration.  This implies that the
operators should be visible wherever the type is visible and being used.

[ChangeLog][Behavior Incompatible Changes] Because the QDataStream and
QDebug serialization operators are automatically registered with
QMetaType, the declarations of those functions must be present at any
point where the type is used with QMetaType and QVariant.

f741a12de1 Disentangle QIODevice dependencies
Move the QIODevice::OpenMode enum into a base class, so that
we can remove the full QIODevice (and thus QObject) dependency
from qdatastream.h and qtextstream.h.

This is required so that we can include QDataStream in qmetatype.h
without getting circular dependencies.

As a nice side effect, QDataStream and QTextStream can now inherit
QIODeviceBase and provide the OpenMode enum directly in their
class scope.

14090760a8 Long Live QMap as a refcounted std::map!
... and QMultiMap as std::multimap.

Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).

Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.

Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.

Miscellanea changes to the Q(Multi)Map code itself:

* consistently use size_type instead of int;
* pass iterators by value;
* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
  take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
  (we're checking for equality, not equivalence!).

Very few breakages occur in qtbase.

[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.

[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).

[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

5a779a4ad3 CMake: Make it possible to build tools when cross-compiling
This patch allows tools to be built for the target platform when the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING parameter is set at configuration
time.

To avoid naming conflicts, the target tools are suffixed with "_native".
The qt_get_tool_target_name() function can be used to get the tool name
for both scenarios (cross and non-cross compilation).

Extend pro2cmake to refer to the right target name for tools.
The relevant write_XXX functions have a new target_ref parameter that
will be "${target_name}" for tools and literally the target name for
everything else.

2cf0ba1fba Use pre-compiled headers when building Qt with cmake

on the headers generated by each module to include in the pch as well
e.g. QtCore/QtCore.

There's also e.g. QtWidgetDepends for QtWidgets, but this only
works for modules, not for tools, examples or other applications.
For now we'll use the Qt<Module>/Qt<Module> headers for the
modules we depend on.

Building with PCH can be disabled with -DBUILD_WITH_PCH=NO, and it only
works for versions of CMake newer than 3.15.20190829.

c7fd10a022 Allow building the tests directory as a standalone CMake project
At the moment, Coin builds tests as a separate qmake invocation
against an installed Qt. We need to support the same with CMake.

Change the tests subdirectory to be a standalone CMake project when
CMake does not detect an existing QtTest target while processing the
subdirectory. If the target exists, it means we are building the whole
repo, if the target does not exist, we need to call find_package
to find the installed Qt.

Refactor and move around a few things to make standalone tests build
successfully:
- add a new macro to set up paths to find QtSetup
- add a new macro to find all macOS frameworks
- add a new macro to set up building tests
- add a new macro that actually builds the tests
- export the INSTALL_CMAKE_NAMESPACE value into the BuildInternals
  Config file
- export the CMAKE_BUILD_TYPE value, because a test project doesn't
  have a .git subdir and thus defaults to be built in Release
  mode, even though qtbase might have been built in Debug, so to
  avoid the mixing, the propagate the build type
- stop overriding INSTALL_CMAKE_NAMESPACE and
  QT_CMAKE_EXPORT_NAMESPACE inside QtSetup if they are set, because
  the tests project doesn't specify a major version, and if we
  override the values, the moc / uic targets don't get the correct
  major version prefix and configuration fails

02a015375a Implement developer / non-prefix builds
A non-prefix build is a build where you don't have to run
make install.

To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).

When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.

Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).

This patch stops installation of any files by forcing the
make "install" target be a no-op.

When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.

The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.

As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.

Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.

The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.

All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.

When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.

Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

42d3b21c92 Export tool config and target files for each relevant module
CMake will now generate config and target files for each module that
provides tools. As a result, namespaced global targets such as
Qt5::moc or Qt5::rcc can be made available.

Third party projects that require just these tools, and not the Qt
modules themselves,  should specify CMAKE_PREFIX_PATH pointing to the
installed Qt location, and call find_package(Qt5CoreTools),
find_package(Qt5GuiTools), etc.

It is also possible to call
find_package(Qt5Tools REQUIRED Core Widgets) where the last option
is a list of modules whose tools should be imported.

Note that all the tools are in the Qt5::
namespace and not in the Qt5CoreTools:: or Qt5WidgetsTools::
namespace.

This commit also changes the behavior regarding when to build tools
while building Qt itself.

When cross compiling Qt (checked via CMAKE_CROSSCOMPILING) or when
-DQT_FORCE_FIND_TOOLS=TRUE is passed, tools added by add_qt_tool will
always be searched for and not built.
In this case the user has to specify the CMake variable QT_HOST_PATH
pointing to an installed host Qt location.

When not cross compiling, tools added by add_qt_tool are built from
source.

When building leaf modules (like qtsvg) that require some tool that was
built in qtbase (like moc), the module project should contain a
find_package(Qt5ToolsCore) call and specify an appropriate
CMAKE_PREFIX_PATH so that the tool package is found.

Note that because HOST_QT_TOOLS_DIRECTORY was replaced by QT_HOST_PATH,
the ensure syncqt code was changed to make it work properly with
both qtbase and qtsvg.

Here's a list of tools and their module associations:
qmake, moc, rcc, tracegen, qfloat16-tables, qlalr  -> CoreTools
qvkgen -> GuiTools
uic -> WidgetTools
dbus related tools -> DBusTools

a1752276e0 CMake: Do not link qmake against Qt (not even the bootstrap one)
Qmake should not rebuild all the code in QtCore, but currently it does.
When linking against QtCore, all the symbols get duplicated. A clever
linker will "deduplicate" the symbols again, so this actually works
with shared Qt builds, but it fails for static builds.

Do not rely on the linker being clever and just do not link Qt at all
for qmake.

3f03917b54 Fix Windows build
- Fix qmake build
- Fix QtNetwork moc-ing, by including the moc files
  inside the cpp files
- Fix sql odbc plugin by including QT_PLUGIN define
- Fix Boostrap to link against the Platform target, to get the
  correct Unicode and WIN64 defines.
- Fix vulkan headers to be found
- Fix freetype bzip and png unresolved symbols / linker issues
  when building minimal platform plugin (also need to make
  sure to use the vcpkg toolchain instead of CMAKE_PREFIX_PATH
  because then find_package is overridden, which does magic
  to properly propagate static library dependencies).
- Fix qfilesystementry test not to be built without private
  tests feature (it led to undefined symbols issues).
- Make sure to remove QT_NO_CAST_TO_ASCII define when building
  QtCore, so that the qstringbuilder3 test builds
  successfully.
