4b2035cd0f Bump Apple platform minimum versions
Includes both minimum deployment targets and minimum sdk
versions.

As per supported Apple platforms versions which was done
in qt/qtdoc at
8807fdedce29cbbd7662fcd745234da30eace3fb

For Qt for iOS 6.0.x we only bump the minimum
deloyment target because applications seem to crash with iOS 12.4+,
and it's better to have a build error than a runtime error.

The minimum required sdk will not be bumped for 6.0.x, so we don't
accidentally break someone's existing build, given that 6.0 is already
released.

9082cc8e8d macOS: Don't hard-code x86_64 as the architecture when using qmake
The qmake variable QMAKE_APPLE_DEVICE_ARCHS was added for iOS,
to support universal builds, as the QT_ARCH is a single value.

Since the qmake macOS builds are non-universal (at the moment),
we remove the hard-coded value for QMAKE_APPLE_DEVICE_ARCHS on
macOS, and let the normal architecture test resolve the arch,
like on other platforms.

To ensure that the following configuration tests are run with
an -arch argument, we trigger a commit of the preliminary Qt
configuration after running the architecture test. This is not
strictly necessary, but makes it clearer what's going on during
configure.

The device_and_simulator configuration option was used by the
iOS toolchain, and needed to be moved up in the configuration
test order to not break later tests.

The logic in mac/default_post.prf for both Xcode and Makefiles
to add -arch flags was kept as is, based on the existing
variable, to avoid too many changes to this logic.

The logic in toolchain.prf was amended to make it clear and
ensure that it only applies to iOS builds. macOS builds do
not have this issue.

f27f9e7bd3 MSVC: enable identical COMDAT folding for release builds
According to Microsoft's docs, /OPT:ICF is enabled by the
linker by default unless /OPT:NOICF or /DEBUG is specified.

If we are in RelWithDebInfo mode, /DEBUG is passed to the
linker to generate debug symbols, however, it caused the
identical COMDAT folding be disabled. We now pass /OPT:ICF
to the linker explicitly to prevent this.

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.

1048d83fc2 Limit OpenGL deprecation silencing on Apple platform to Qt itself
Apple deprecated the entire OpenGL API in favor of Metal, which
we are aware of, so we don't need to see the warnings when building
Qt.

Instead of applying the silencing globally for all Qt consumers,
both internal and external, we now limit the silencing to Qt itself.
That means user code that explicitly uses any of the deprecated APIs
will see the warnings. Note that this does not apply to merely using
any of the Qt OpenGL APIs. The user has to explicitly use the platform
APIs that have been deprecated.

The warnings need to be disabled on a build system level, so that
that they are passed as -D flags on the command line. If the defines
were done in Qt headers (qguiglobal.h e.g.), they would require the
user to always include this header before any of the Apple headers.

752497910b Remove ANGLE
This marks the end of EGL and OpenGL ES support on Windows.

The concepts of -opengl dynamic, -opengl desktop, QT_OPENGL=software,
etc. remain unchanged, with the exception of the disapperance of
everything ANGLE related.

CMake builds now work identically to qmake on Windows: they default to
'dynamic' OpenGL on Windows, unless -DINPUT_opengl=desktop is specified.

On Windows, Qt 6 is expected to default to the "dynamic" OpenGL model by
default, just like Qt 5.15. This can be changed by switching to "desktop"
OpenGL, which will link to opengl32 (publicly, so other libs and applications
will do so as well) and disallows using another OpenGL DLL.

The "dynamic" mode is essential still because the fallback to a software
rasterizer, such as the opengl32sw.dll we ship with the Qt packages,
has to to work exactly like in Qt 5, the removal of ANGLE does not
change this concept in any way (except of course that the middle option
of using ANGLE is now gone)

When it comes to the windows plugin's OpenGL blacklist feature, it works
like before and accepts the ANGLE/D3D related keywords. They will
then be ignored. Similarly, requesting QT_OPENGL=angle is ignored (but
will show a warning).

The D3D11 and DXGI configure time tests are removed: Qt 5.14 already
depends on D3D 11.1 and DXGI 1.3 headers being available unconditionally
on Win32 (in QRhi's D3D11 backend). No need to test for these.

[ChangeLog][Windows] ANGLE is no longer included with Qt. Dynamic OpenGL
builds work like before but ANGLE is no longer an option. OpenGL proper
or an alternative opengl32 implementation are the two remaining options
now. Attempting to set QT_OPENGL=angle or Qt::AA_UseOpenGLES will have
no effect on Windows.

This adds instrumentation to the binaries. At the end of their
execution, these will then write a file containing information which code
was executed. This can be used for code coverage analysis.

[ChangeLog][QtCore][configure] Add switch "-coverage source-based" to
enable clang's "source-based" code coverage feature. This can be used
for code coverage analysis.

6e42ed217c configure: Add sanitizer "fuzzer-no-link"
Adds instrumentation for fuzzing to the binaries but links to the usual
main function instead of a fuzzer's. The similar sanitizer "fuzzer"
should then be used only for building the test itself.

Requires clang 6 or higher.

8ffb200153 Fix LTCG linker flags for macOS with separate debug info
The linker must not throw away the lto.o file. We now instruct the
linker to create a non-temporary lto.o, dependent on the target name.

In order to do that we introduce a new mkspec variable
QMAKE_LFLAGS_LTCG_SEPARATE_DEBUG_INFO. This variable can contain
single-$ variable references that get evaluated when loading ltcg.prf.

2e63d12183 Update supported platforms and build requirements for Apple platforms
Per earlier discussions we bump the deployment target for LTS releases
and follow up by requiring the latest SDK available for building.

As layer backed views and dark mode is a lot more stable these days in
Qt and on macOS in general we no longer support the option to build with
the 10.13 SDK. A workaround in case this functionality is still needed
is to explicitly set the QMAKE_MAC_SDK_VERSION qmake variable, which
will tell the linker to write that version into the MachO header of
the executable, which will then be read by AppKit when determining
which features to opt in to.

780137d585 QRandom: add support for RDSEED
The Intel whitepaer[1] recommends using the RDSEED over RDRAND whenever
present. libstdc++ from GCC 10 will also use it in std::random_device.

[ChangeLog][QtCore][QRandomGenerator] The system() random generator will
now use the RDSEED instruction on x86 processors whenever available as
the first source of random data. It will fall back to RDRAND and then to
the system functions, in that order.

4d289edb14 Disable debug-and-release builds for MinGW
The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.

MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.
