755c678f0f Provide calendar backends with a unique ID
Registration by ID allows for detection of duplicate instantiation of
built-in back-ends, which can be detected and flagged by setting the
ID to ~size_t(0) instead of the enum value for which it sought to be
registered. A new method, calendarId(), is provided to access this;
while the old calendarSystem() becomes non-virtual, as it can be
inferred (when registration was successful) from the ID.

Make registration by name or alias conditional on successful
registration by ID. Previously, failed registration by name precluded
registration by ID, which now becomes the authoritative registration.
This incidentally makes it possible to add a QCalendar constructor
taking the unique ID of a backend, for use in conjunction with custom
calendar implementations.

530b629349 Do not rewrite boolean INPUTs if they have a corresponding feature
Initial replacement of boolean INPUT_ variables to the FEATURE_
variables was wrongly changed to updating of the INPUT_ variable
value to ON/OFF value. This causes potential issues when INPUT_
variable has explicit check for 'yes' or 'no'.
The feature evaluation step enables FEATURE_ variables in case if
the corresponding INPUT_ variable contains a positive CMake value.
So there is no need to process boolean INPUTs at the argument
processing step.
Also no need to keep the special opengl case, since it will be
processed correctly.

09cc63d425 tst_qapplication: Prevent desktopaware test from deactivating main test
Applications on macOS are automatically activated (put into the foreground),
when launched from the Finder, or via 'open' on the command line. But when
launched from the terminal, e.g. foo.app/Contents/MacOS/foo, the application
will launch in the background (inactive).

In Qt we override this behavior, activating the app even when launched from
the terminal, as a convenience, as long as the application is a GUI application.

Unfortunately this means that when tst_qapplication launches a subprocess that
is a GUI app, it will steal activation from tst_qapplication, which in turn
will break tests that later try to activate a window and check that the window
is then active. The window will not be active until the application is active.

We can work around it by preventing Qt from activating the application, but
ideally we'd find a better solution to this, as we don't want to sprinkle
overrides all over our tests.

1702393644 Run headers_clean check with C++20 (gcc, clang)
The headers are already somewhat tested with C++17 in the regular
build. So let's try in the headers_clean check with C++20 instead.

Using C++20 with MSVC 19.28 doesn't work yet though:

  corelib/tools/qalgorithms.h(247): error C2039: 'popcount': is not a member of 'std'
  corelib/tools/qhashfunctions.h(311): note: see declaration of 'std'
  corelib/tools/qalgorithms.h(247): error C3861: 'popcount': identifier not found

6bdffefaa8 Fix QTimer::setInterval to remove existing bindings
A recent change ( a7ca8b1a28 )
led to failure of binding removal in setInterval().
This was fixed by introducing setterScope.
This patch add unit tests for this regression.

18bf641777 Use newlines more consistently in generate compile-test code
The generated code contained many repeated blank lines.
Most main()s were preceded by one, but not all.
Only include blank lines for actual empty entries in lists, where
configure.json specified them, plus one before main if anything else
precedes it.

c462793d67 Drop parsing of antique TextDate format
Apparently we used to have (back in 2007, only on Windows,
incompatibly with what we were then using on Unix) a TextDate format
(only for QDateTime, QDate used what it still uses) that put the
day-of-month number, with a dot after it, before the month's short
name. We have retained parsing of this format, on all platforms, ever
since.

It no longer matches the format we now use (since 5.2, in 2013, commit
61b56a89a1, which harmonised the format
with Unix and QDate); now seems like a good time to stop complicating
our parser for its sake.

[ChangeLog][QtCore][QDateTime] The parsing of Qt::TextDate in
QDateTime::fromString() no longer supports the old TextDate format
used (only) on Windows by Qt < 5.2 ("ddd d. MMM yyyy" with an
"HH:mm:ss" time either appended or inserted before "yyyy").

517578e071 QDateTime::toString(): use UTC-offset as time-zone suffix
Since fromString() can't parse the (ambiguous at the best of times;
also backend-dependent and thus potentially system-locale-dependent)
abbreviations currently produced (since 5.9) and can parse UTC-based
offsets, the OffsetName of the zone is a more robust format for the
zone-suffix. This also makes it possible to consistently use the C
locale, compatibly with everything else about post-6.0 date-time
serialization.

[ChangeLog][QtCore][QDateTime] When spec is Qt::TimeZone, the
offset-suffix now used for the toString(Qt::TextDate) format is now a
UTC-based offset string, compatible with the parsing (now) supported
by fromString(). The zone-abbreviation suffix in use since 5.9 was not
parseable.

3cf84287e7 Prepare TextDate to use UTC-offset rather than GMT-offset zone suffixes
There are GMT-offset zones whose convention for the sign of the offset
is the reverse of what we are (still) using, which is the usual
convention for UTC-offset zone: for example, the Olson Database's
Etc/GMT+3 has offset -3 hours in the UTC-based system we use, so we
give it suffix GMT-0300. The UTC-based suffix is also what we use as
the abbreviation for OffsetFromUTC() in toString().

For now this only adds support for parsing a planned future form: the
old form using GMT is retained, to give client code some chance to
prepare for a backwards-compatible transition. Although the GMT prefix
is matched case-insensitively, only match UTC if fully upper-case;
there is no meaningful precedent for case-insensitive usage here.

[ChangeLog][QtCore][QDateTime] The Qt::TextDate format now recognizes
UTC-based offset suffixes in addition to suffixes based on the
deprecated alias GMT. This prepares for toString() to use such
UTC-based suffixes for time-zones (fromString() cannot parse the
present abbreviation suffix). A future release of Qt shall use
UTC-based suffixes in place of the present GMT-based suffixes (which
conflict with GMT-based IANA zone names) for Qt::LocalTime and
Qt::OffsetFromUTC time-specs. Client code is encouraged to use and
recognize UTC-based zone suffixes in preparation for that transition,
unless compatibility with versions before 6.2 is required.
