The history of that one line of code is... interesting, to say the
least. `defaultConnection` was originally declared as `char *`, which
happened to work on older MSVC versions. Then it gained a workaround for
other platforms by conditionally marking it const, with a const_cast to
keep the code working on MSVC. Now it is unconditionally declared as a
const char *, but the const_cast is still there. Get rid of it.

The QAndroidApplication::runOnAndroidMainThread() function creates a
task on QThreadPool::globalInstance() to wait for a timeout and cancel
the QFuture representing the task.
It does so by passing a lambda to QThreadPool::start(std::function)
that captures the future, a local variable, by reference. This is UB
when the lambda is ever executed, because the local stack variable's
lifetime will have ended.
To fix, simply capture the future by value, not by reference. Since
QFuture::cancel() is not const, we need to make the lambda mutable.

QtBase didn't contain any checks for QT_RESTRICTED_CAST_FROM_ASCII, so
a recent addition to the QString::append/insert/prepend overload set
made calls with C string literal arguments ambiguous without the CI
noticing. We had a similar problem with QString::multiArg.
To increase test coverage, we now run tst_qstring two times:
- without any define
- with QT_RESTRICTED_CAST_FROM_ASCII (lots of changes necessary)
Most removals are expected, because they disable tests that check the
implicit conversions from QByteArray and const char*, but the
relational operators with QLatin1String objects might warrant fixing.
In some places, when the conversion wasn't the functionality under
test, replaced C string literals or QByteArrays with QLatin1String.
We should also test with QT_NO_CAST_FROM_ASCII, but that's even larger
surgery.
QString doesn't have a ctor from std::nullptr_t, so QString s =

QtMiscUtils functions are inline constexpr.
¹ isdigit could give a false positive on non-US-ASCII-digits, I
suppose.
As a drive-by, rely on the QtMiscUtils::fromHex() returning a negative
value when a non-hex character was encountered, to avoid the extra
isxdigit() checks. This property is preserved through the bit
manipulations: ORing together negative values yields a negative number
iff either or both operands were negative (in two's complement, which
Qt requires). The caller also checks the array bounds before calling,
so the isxdigit() calls didn't act as an implicit bounds check
(returning false if they encounter '\0'), either.
