The comparison between nullptr and QWeakPointer was just bogus
and ill-formed. The INTEGRITY compiler catches that even if
nothing tries to use the comparison. It is an ill-formed, no
diagnostic required case of a function template never being
able to produce a valid specialization. And while we're at
it, this patch makes the result of comparing a nullptr to
a QWeakPointer or vice versa the same as asking .isNull() from
the weak pointer, because it seems mind-boggling if those
are not the same operation.

With C++20, there is a new iterator_category: contiguous_iterator, for
containers whose elements are stored contiguously in memory. In Qt 6,
QList satisfies this requirement.
However, we still need to tell the standard machinery about it. Step one
is to mark the iterators as contiguous_iterator; as that exists only in
C++20, we have to ifdef accordingly.
We also have to ensure that the iterators satisfy pointer_traits by
defining element_type due to how contiguous_range is specified. As this
runs afoul of LWG 3346, we check for known bad _GLIBCXX_RELEASE
versions.

requires that we construct the new items in the list in order
and increment the size each time we constructed a new item.
Not having a code path that potentially calls destructors should
avoid the generation of lots of additional code for those
operations. In addition, the forward and backwards code paths
are now unified and only require somewhat different setup of
some variables at the start.
This gives us strong exception safety when appending one item,
