std::function, which is used to store the type-erased continuation
lambdas, requires the passed callable to be copy-constructible. This
makes impossible to use move-only callables with continuations/handlers.
In particular, it makes impossible passing lambdas that are capturing
move-only objects. The workaround is to store the continuation lambda
inside a wrapper for the callable, which stores the move-only lambda in
a QSharedPtr and can be stored in std::function, since it's copyable.

The only documented replacements for Q*String*::arg() are sequences like
%1, %2, %3 -- where the n-th number is expressed using a sequence of
ASCII digits [1].
The code parsing the replacements however used the QChar::digitValue()
function. That function simply checks if a QChar has a *Unicode digit
value* (no matter what its block/category is), and if so, returns the
corresponding digit value as an int (otherwise returns -1).
The result of this is that a sequence like "%¹" or "%१" actually
triggered substitutions (both count as "1"). Similarly, QChars with
a digit value would be parsed as part of longer sequences like "%1²"
(counting as "12" (!)).
This behavior is weird, undocumented, and extremely likely the usual
backstabbing by Unicode by using "convenience" QChar methods -- that is,
never *intended* by the implementation.
This commit deprecates (via warnings) such usages, which for the time
being are left working as before (in the name of backwards
compatibility). At the same time: given it's extremely unlikely that
someone would be deliberately relying on this behavior, it implements
the desired change of behavior (only accept sequences of ASCII digits)
starting from Qt 6.6, that is, after the next LTS.
Throughout Qt 6's lifetime users will still be able to control arg()'s
behavior by setting an env variable, but that variable (and the support
for Unicode digits) will disappear in Qt 7.
To summarize:
* Qt 6.3->6.5: default is Unicode digits, env var to control
* Qt 6.6->6.x: default is ASCII digits, env var to control
* Qt 7: only ASCII digits, no env var
[1] That's the name Unicode gives to them, cf. https://www.unicode.org/charts/PDF/U0000.pdf
[ChangeLog][QtCore][Deprecation Notices] The arg() functions
featured in Qt string classes have always been documented to require
replacements tokens to be sequences of ASCII digits (like %1, %2, %34,
and so on). A coding oversight made it accept sequences of arbitrary
characters with a Unicode digit value instead. For instance, "%2੩" is
interpreted as the 23rd substitution; and "%1²" is interpreted as the
12th substitution. This behavior is deprecated, and will result in
runtime warnings. Starting from Qt 6.6, arg()'s behavior will be changed
to accept only ASCII digits by default. That means that "%1²" is going
to be interpreted as substitution number 1 followed by the "²" character
(which does not get substituted, so it gets left as-is in the result).
Users can restore the previous semantics (accept Unicode digits) by
setting the QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG environment
variable to a non-zero value. In Qt 7, arg() will only support sequences
of ASCII digits. Note that from Qt 6.3 users can also set
QT_USE_UNICODE_DIGIT_VALUES_IN_STRING_ARG to zero; this will make arg()
use ASCII digits only, in preparation for the future change of defaults.

Q(Multi)Map mutating functions that take reference to a key and/or a
value (e.g. insert(), take(), etc.) must make sure that those references
are still valid -- that is, that the referred objects are still alive --
after the detach() call done inside those functions.
In fact, if the key/value are references into *this, one must take extra
steps in order to preserve them across the detach().
Consider the scenario where one has two shallow copies of QMap, each
accessed by a different thread, and each thread calls a mutating
function on its copy, using a reference into the map (e.g.
map.take(map.firstKey())). Let's call the shared payload of this QMap
SP, with its refcount of 2; it's important to note that the argument
(call it A) passed to the mutating function belongs to SP.
Each thread may then find the reference count to be different than 1 and
therefore do a detach() from inside the mutating function. Then this
could happen:
Thread 1: Thread 2:
detach() detach()
SP refcount != 1 => true SP refcount != 1 => true
deep copy from SP deep copy from SP
ref() the new copy ref() the new copy
SP.deref() => 1 => don't dealloc SP
set the new copy as payload
SP.deref() => 0 => dealloc SP
set the new copy as payload
use A to access the new copy use A to access the new copy
The order of ref()/deref() SP and the new copy in each thread doesn't
really matter here. What really matters is that SP has been destroyed
and that means A is a danging reference.
Fix this by keeping SP alive in the mutating functions before doing a
detach(). This can simply be realized by taking a local copy of the map
from within such functions.
remove() doesn't suffer from this because its implementation doesn't do
a bare detach() but something slightly smarter.

and both were stored separately when streaming through QDataStream. The
families list was treated as an extension of family in this case, and
the primary font family was always the singular family property.
In Qt 6, it has been merged into one and family() is now just a
convenience for families().at(0).
But when reading files generated with Qt 5, we would ignore the fact
that these were previously separated. We would first read the family
entry into the families list, and then we would later overwrite this
with an empty families list.
Instead, we detect streams created with Qt 5.15 or lower and make sure
we append the families list instead of overwriting it in this case. In
addition, we need to make sure we split up the list again when
outputting to Qt 5.x.
This adds a file generated with QDataStream in Qt 5.15 to the test to
verify.
[ChangeLog][Fonts] Fixed a problem deserializing the family of fonts
that had been serialized using QDataStream in Qt 5.

QObjects must be deleted if the QCoreApplication is being destroyed.
This was previously done by implementing custom code in qtbase and
other modules. So unify it and introduce a Q_APPLICATION_STATIC,
based on the Q_GLOBAL_STATIC, which centralises the logic.
Since we still have a few remaining living QObjects,
this comes in handy to fix those as well.
