mkspecs/features/qt.prf adds a dependency on the system threading
library if the Qt Core thread feature is enabled. Because qt.prf is
loaded by any public or internal Qt project, it's essentially a public
dependency for any Qt consumer.
To mimic that in CMake, we check if the thread feature is enabled, and
and set the Threads::Threads library as a dependency of Qt6::Platform,
which is a public target used by all Qt modules and plugins and Qt
consumers.
We also need to create a Qt6Dependencies.cmake file so we
find_package(Threads) every time find_package(Qt6) is called.
For the .prl files to be usable, we have to filter out some
CMake implementation specific directory separator tokens
'CMAKE_DIRECTORY_ID_SEP' aka '::@', which are added because we call
target_link_libraries() with a target created in a different scope
(I think).
As a result of this change, we shouldn't have to hardcode
Threads::Threads in other projects, because it's now a global public
dependency.

Remove QDestopWidget public header, simplify the implementation that

QWidget's initial target screen into a QScreen pointer.

returns a QWidget pointer, so that applications and widgets can get
access to the root widget for a specific screen without having to
resort to private APIs.
QDesktopWidgetPrivate implementations to look up a screen for an index,
widget, or point are now all inline functions that thinly wrap
QGuiApplication::screens/screenAt calls. We should consider adding those
as convenience APIs to QScreen instead.
Note that QWidget::screen is assumed to return a valid pointer; there is
code that handles the case that it returns nullptr (but also code that
trusts that it never is nullptr), so this needs to be defined, verified
with tests, and asserted. We can then simplify the code further.

In Coin when provisioning for Android, we download and configure
the OpenSSL package, but don't actually build it. This means that
find_package(OpenSSL) can find the headers, but not the library,
and thus the package is marked as not found.
Previously the openssl_headers feature used the result of finding
the OpenSSL package, which led to it being disabled in the above
described Android case.
Introduce 2 new find scripts FindWrapOpenSSL and
FindWrapOpenSSLHeaders. FindWrapOpenSSLHeaders wraps FindOpenSSL,
and checks if the headers were found, regardless of the OpenSSL_FOUND
value, which can be used for implementing the openssl_headers feature.
FindWrapOpenSSL uses FindWrapOpenSSLHeaders, and simply wraps the
OpenSSL target if available.
The find scripts also have to set CMAKE_FIND_ROOT_PATH for Android.
Otherwise when someone passes in an OPENSSL_ROOT_DIR, its value will
always be prepended to the Android sysroot, causing the package not
to be found.
Adjust the mapping in helper.py to use the targets created by these
find scripts. This also replaces the openssl/nolink target.
Adjust the projects and tests to use the new target names.
Adjust the compile tests for dtls and oscp to use the
WrapOpenSSLHeaders target, so that the features can be enabled even
if the library is dlopen-ed (like on Android).

This leads to "make benchmark" actually running the benchmark, which
would be nice, I think. Purged various CONFIG += release or -= debug
lines from the same configurations; those surely only configure how
the test code is compiled, which is more or less pointless; it's the
code under test whose debug/release state matters, and I don't suppose
that's affected by the build config of the test code.
In the process, reduce diversity of the ordering of lines within these
*.pro files and purge some dangling space.

Constantly re-reading the timezone information only to be told the exact
same thing is wildly expensive, which can hurt in operations that cause
a lot of QTimeZone creation, for example, V4's DateObject - which
creates them a lot (in DaylightSavingTA).
This performance problem was identified when I noticed that a
QDateTime binding updated once per frame was causing >100% CPU usage
(on a desktop!) thanks to a QtQuickControls 1 Calendar (which has a
number of bindings to the date's properties like getMonth() and so
on).
The newly added tst_QTimeZone::systemTimeZone benchmark gets a ~90%
decrease in instruction count:

PASS : tst_QTimeZone::systemTimeZone()

+ 0.0036 msecs per iteration (total: 59, iterations: 16384)
Also impacted (over in QDateTime) is
tst_QDateTime::setMSecsSinceEpochTz(). The results here are - on the
surface - less impressive (~0.17% drop), however, it isn't even
creating QTimeZone on a hot path to begin with, so a large drop would
have been a surprise.

traverse transitions.

The concept was a nice idea to avoid accidental detach() calls
in implicitly shared containers, but it conflicts with a C++11

taking a const_iterator as argument and returning an iterator

QTimer::singleShot is optimized for zero timeouts when using the API
taking a string method name. This optimization was not used for the API
taking a PMF or functor. This patch adds it, making the various API
calls behave similarly from a performance point of view.
The approach taken here requires a QObject context object. If none is
available, e.g. a nullptr was passed explicitly, or the
QTimer::singleShot(O, Functor) API was used, the optimization could
not easily be applied. This is not only bad from a performance POV,
but also poses as a potential source for heisenbugs: Using the
different API versions of QTimer::singleShot would use different code
paths internally, which then would not ensure the expected slot call
order. This problem actually existed already when mixing the
string-based slot syntax with PMF/functors in the QTimer::singleShot
API.
This patch overcomes this hurdle and fixes all of the above: When we
encounter a 0ms single shot timer, and no QObject context object is
available, we fall back to the main thread, or create a temporary
QObject for any other thread. The updated and extended benchmark
shows that this is still a significant performance improvement
over using a timer:

Extended the existing qFuzzyCompare tests to probe the boundaries of
the ranges of values of both types, in the process.
Revised the toString<double> that qCompare() uses to give enough
precision to actually show some of the differences being tested there
(12 digits, to match what qFuzzyCompare tests, so as to show different
values rather than, e.g. 1e12 for both expected and actual) and to
give consistent results for infinities and NaN (MinGW had eccentric
versions for these, leading to different output from tests, which thus
failed); did the latter also for toString<float> and fixed stray zeros
in MinGW's exponents (which made a kludge in tst_selftest.cpp
redundant, so I removed that, too).
That's further complicated handling of floating-point types, so let's
just keep an eye on how expensive that's getting by adding a benchmark
test for QTest::toString(). Unfortunately, default settings only get
runs that take modest numbers of milliseconds (some as low as 40)
while increasing this with -minumumvalue 100 or more gets the process
killed - and I'm unable to find out who's doing the killing (it's not
QProcess::kill, ::kill or the QtTest WatchDog, as far as I can tell).
So results are rather noisy; the integral tests exhibit speed-ups by
factors up to 5, and slow-downs by factors up to 100, between runs
with and without this change, which does not affec the integral tests.
The relatively modest slow-downs and speed-ups in the floating point
tests thus seem likely to be happenstance rather than signal.

QFile/QFileInfo::readLink() functions are obsolete but were not marked
as deprecated.
Explicit mark them as deprecated so they can be removed with Qt6.
