These were found with the help of -Wdangling-reference, which is
new in GCC 13.
The one in qtpaths.cpp is a false positive: parseLocationOrError()
returns a reference, so there's nothing for the full expression to
destroy. Moreover, it returns a reference to a static object, so
there's no destruction inside the function either.
The other two aren't, but are also harmless. QDBusMessage::arguments()
and QVariant::toList() return a stored QVariantList by value, so
QList's COW mechanism means at() returns a reference that will not be
destroyed. However, the compiler has no way of knowing that. And
since it depends on the implementation details, change the code to
not depend on that.

This is part of a series of patches deprecating implicit conversions
of QAtomic<T> variables to T.
Use relaxed atomic loads and stores on the 'isDebugging' variable. The
old code used the implict conversions to and from int and therefore
loadAcquire/storeRelease. Here, the int is the only value, it's not
guarding the construction of any other data, so relaxed loads and
stores suffice.
A further optimization would be to make the initial value of
isDebugging 0, to send it into the BSS instead of the TEXT/DATA
segment, but seeing as this is just compiled in for the auto-tests,
this patch leaves that particular change for another round (or never).

QVector = QList, and QList::iterator isn't a pointer, but converts

pointers. In preparation for deprecating conversions between them,

If more than one signal parameter required conversions (e.g. 2

Found with valgrind after the QtApplicationManager started crashing
weirdly when built against Qt 6. The same code is in Qt 5, but it
just works fine there: I guess the reallocation strategy in QList is
different there, so we never have to reallocate the list.
