233ca06500 rsslisting example: move default URL to main()
It felt more natural that the RSSListing class would be agnostic about
the default URL, so let it be a constructor parameter. In the process,
update the URL to what the old one now redirects to (thanks to Ivan
Solovev for spotting that) and make the constructor explcit (thaks to
Ievgenii Meshcheriakov for suggesting this).

3cdc65c2ec rsslisting example: Tidy up #include usage
Replace one #include with a forward-declaration - in rsslisting.h QUrl
is only passed by reference to a function. Shuffle order of existing
forward declarations to be alphabetic, in the process.

Shuffle #include order in sources so that this example's own headers
appear before the Qt ones.

1371cd107a Add metadata to serialization examples
There's no separate category for {de,}serialization, so I've put them
in Input/Output; and at least some of them are relevant to
transmission over the network, so include that as a tag, so that
someone writing a network application that wants to use what they
illustrate gets a chance of being lead to it.

179b61c85f Update cbordump image to a higher-resolution one
Incidentally using reversed video, too, as that's what came naturally
to the terminal I was using. File is smaller, but text in the new
image is considerably more readable and the image is bigger.

The examples guideline calls for an image giving some idea what the
example is about, with a 4:3 or 5:4 aspect ratio. An image shorter
than its width wasn't practical, and getting a useful amount of
information in a height less than 3/2 of the width would have required
widening into blank space purely to satisfy the aspect ratio.  The
prior image's ratio was about 12:7, the new one's is roughly 2:3.

The old image showed the start of cbordump -a output, which is rather
less illuminating than the default output of formatted data; it's also
rather verbose, so was cut off part way through. It does, however,
illustrate how the annotated form might be useful for debug
purposes. The image also had a lot of blank space to the right of the
text of interest, wasting roughly half of its width; it could easily
have been cropped to 1:1 without loss of information. As example
data-set, it used ../savegame/save.dat, but without any hint to how to
generate that.

I decided to include a hint to how to generate a CBOR data file to
dump, then show the standard output and only the beginnings of the
annotated output, as the latter (even on its own) would make the
aspect ratio considerably taller. In the context of the standard
display, the preamble of the annotated one gives a reasonable feel for
what's going on, without belabouring the point.

5a3ac484db savegame ex.: revamp the way we (de)serialize JSON
JSON, unlike, say, QDataStream, allows building up objects independent
of some central object, and combining them into a QJsonDocument
later. This suggests returning QJsonObjects from a toJson() const
method instead of having the caller supply a QJsonObject. Doing it
this way enables transparent move semantics to kick in, too.

For deserialization, use a fromJson() named constructor for value-like
classes (where identity doesn't matter, only equality). Keep using
read(), too, and add a note to explain when to use which form.

Also, avoid the triple lookup from

   if (json.contains("key") && json["key"].isSoughtType())
      mFoo = json["key"].toSoughtType();

by using C++17 if-with-initializer and showing the trick with
Undefined never being of isSoughtType():

   if (const QJsonValue v = json["key"]; v.isSoughtType())
      mFoo = v.toSoughtType();

Adjust the discussion to match the new code, up the copyright years
and rename some qdoc snippet markers from nondescript [0]/[1] to
[toJson]/[fromJson].

55fe3ee5e7 Replace runic XSLT with a python script and tidy cbordump code
Filters records on having value < 256, or an RFC, previously hacked
into the XSLT to produce the last update, with a bit of hand-editing.
Using a python script makes it easier to control the formatting and
other details; for example, severl entries previously had descriptions
that mentioned their RFC, with specific section, to which the XSLT was
adding a redundant mention of the RFC. It is also possible to exploit
C++ string juxtaposition to get tidily-presented string literals,
without having to resort to raw strings.

* android:allowBackup="true": this has to be explicitly set, we set it
to the default value here [2].
* android:fullBackupOnly="false": SDK 23+ use this to deteremine to

bcab157f75 Update table of CBOR tag descriptions in cbordump example
A comment said how to do this, so I gave it a try. Added a note to the
instructions to save the next person to look at this from, as I
initially did, thinking the comment in the generated code had the URL
wrong.

It turns out that some of the newer additions to the IANA registry
have semantics elements that spread across several lines. I don't know
the XSLT magic to replace each newline in a value, along with its
preceding and following spacs, by a single space, so adapted the XSLT
to produce C++ raw strings to wrap these multi-line entries. That'll
produce somewhat ugly output, so left a TODO for the better solution.

fddeec60cb Wait conditions example: fix an incorrect condition variable usage
3a449bbb69 amended the code to remove
acquiring a lock when waking up a condition variable. It is fine to
not have a lock associated when waking a condition variable; what I
misunderstood was the scope of the lock, which (and this underlines
the importance of commenting _what exactly_ a lock protects, for
each and ever lock) protected both the buffer as well as the counter
of the buffer. This made my reasoning flawed: it is necessary to keep
the lock while notifying, otherwise the counterpart could verify the
condition isn't satisfied and wait (e.g. see numUsedBytes==0), missing
the wake from the other thread (which could arrive between the check and
the wait).

Amends the previous commit.

* Unlock the mutex before notifying the condition variables.

* Condition variables are always meant to be used in a while loop, and

ef935f6e37 Plumb public permission APIs to Android backend
The lock and unlock of the Android deadlock mutex is now part
of the internal implementation instead of limited to the enum
based permission API. It is unclear why 8bca441b6f added
the guard only to this API and not to the string based API
as well.

The check for isBackgroundLocationApi29 has been removed,
as the logic seemingly resulted in accepting every single
permission type except location permissions if used via
the enum-based API.

Since Android's platform permission API doesn't have an
Undetermined status, we keep a hash of the status for each
permission type, and by default checkPermission() would
return Undetermined, until a requestPermission() call
is done which updates the internal hash, and after that
checkPermission() would return properly Granted/Denied.

f0a7d74e1d Add permission API backend for macOS and iOS
When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.

To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.

Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

33cf9d32da Long live QPermissions!
Many features of today's devices and operating systems can have
significant privacy, security, and performance implications if
misused. It's therefore increasingly common for platforms to
require explicit consent from the user before accessing these
features.

The Qt permission APIs allow the application to check or request
permission for such features in a cross platform manner.

The check is always synchronous, and can be used in both
library and application code, from any thread.

The request is asynchronous, and should be initiated from
application code on the main thread. The result of the request
can be delivered to lambdas, standalone functions, or
regular member functions such as slots, with an optional
context parameter to manage the lifetime of the request.

Individual permissions are distinct types, not enum values,
and can be added and extended at a later point.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

To simplify executing a similar task and to diminish the duplication of

`\externalpage` commands directing to RFC locations, was enhanced with
links to all RFCs that were mentioned in the current documentation, so
as to aggregate this common category of links.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

0e69349f6f Brush up the mandelbrot example
The example refines the image by running a number of passes
with increasing number of iterations, which is not really
visible to the user. Set an informational text string on
the generated image which provides this information
along with the elapsed time.
The idea is to do the same to the corresponding
Qt for Python example to have some sort of speed comparison
for number crunching.

Add a command line option for the number of passes.

Make the window a bit larger to accommodate the
information.

89f7a2759c Deliver Quit event when calling QCoreApplication::quit()
Instead of QCoreApplication::quit() directly calling exit(0), which would
leave QGuiApplication and client code out of the loop, we now send the
Quit event, and let it pass through event delivery, before finally ending
up in QCoreApplication::event(), where we call exit(0).

This has the advantage that QGuiApplication can ensure all windows are
closed before quitting, and if any of those windows ignore the close
event the quit will be aborted. This aligns the behavior of synthetic
quits via QCoreApplication::quit() with spontaneous quits from the
platform via QGuiApplicationPrivate::processApplicationTermination.

Clients who wish to exit the application without any event delivery or
potential user interaction can call the lower level exit() function
directly.

[ChangeLog][QtGui] Application termination via qApp->quit() will now
deliver Quit events to the application, which in turn will result in
application windows being closed as part of the application quit,
with an option to cancel the application quit by ignoring the close
event. Clients who explicitly want to exit the application without
any user interaction should call QCoreApplication::exit() explicitly.

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.

Note that this is a mere search/replace; some places were using
double braces to work around the presence of commas in a macro, no
attempt has been done to fix those.

tst_qglobal had just some minor changes to keep testing the macro.

I made a clazy automated check that replaced the use of QVariant::Type
by the equivalent in QMetaType.
This has been deprecated since Qt 5.0, but many uses were not yet removed.

In addition, there was some manual changes to fix the compilation errors.

Adapted the Private API of QDateTimeParser and QMimeDataPrivate
and adjust QDateTimeEdit and QSpinBox.

QVariant(QVariant::Invalid) in qstylesheet made no sense.

But note that in QVariant::save, we actually wanted to use the non-user type.

In the SQL module, many changes were actually reverted because the API
still expects QVarient::Type.

care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.

99539a2894 Allow to build examples as standalone project
Create CMake config files which can be used from the very same CMake
project. These CMake config files simply do not create any targets,
controlled via the QT_NO_CREATE_TARGETS.

This patch also allows to build qtbase.git:examples as a standalone
project, against an already-built Qt.

Ran this:
  ag -s "QT " examples -l -0 | xargs -0 -n 1 .../util/cmake/pro2cmake.py --is-example

c19d556863 QVariant: deprecate qVariantFromValue/qVariantSetValue()
qVariantFromValue/qVariantSetValue() was marked as obsolete since Qt4.
Therefore mark them as deprecated with Qt5.14.
Since QVariant::setValue/fromValue() were using the now deprecated
functions move the implementation to them and let
qVariantFromValue/qVariantSetValue() call
QVariant::setValue/fromValue().
