Views / delegates absolutely *adore* hammering data(). A simple
QListView showing a couple of dozens entries can call data()
a hundred of times on the first show.
Back of the hand calculation,
* 2 times per visible item (sizeHint() + paint()),
* times 9 roles used by the default delegate,
* times 20 visible items
= 360 as a bare minimum, assuming the view doesn't redraw twice
accidentally. Move the mouse over the view, and that'll cause
a full update with certain styles: 360 calls to data() per update.
This has an overhead visible in profilers. The model's data()
has to re-fetch the index from its data structure and extract
the requested field every time.
Also, QVariant is used for the data interexchange,
meaning anything that won't fit in one is also a memory allocation.
This problem will likely be gone in Qt6Variant as that
will store sizeof(void*) * 3, meaning QImage/QPixmap and similar
polymorphic classes will fit in a QVariant now...
So I'm trying to to remove part of that overhead by allowing
views to request all the data they need in one go. For now,
one index a a time.
A view might also store the data returned. The idea is that
the same role on different indexes will _very likely_
return variants of the same type. So a model could move-assign
the data into the variant, avoiding the memory allocation
/deallocation for the variant's private.
This patch:
1) Introduces QModelRoleData as a holder for role+data.
2) Introduces QModelRoleDataSpan as a span over QModelRoleData.
The idea of a span type is twofold. First and foremost, we are
in no position to choose which kind of container a view should
use to store the QModelRoleData objects for a multiData() call;
a span abstracts any contiguous sequence, leaving the view free
to do whatever it wants (statically allocate, use a vector, etc.).
It also solves the problem of efficient passing the roles and
gathering the returned variants from multiData().
3) Add multiData(), which populates a span of roles for a given
model index. The main advantage here is that a model can fetch
all the needed information for a given index just once, then
iterate on the span and provide data for each requested role.
Cf. this with data(), where every call has to re-fetch
the information for the index.
A couple of models have been ported to multiData(), as well as
QStyledItemDelegate.
[ChangeLog][QtCore][QModelRoleData] New class.
[ChangeLog][QtCore][QModelRoleDataSpan] New class.
[ChangeLog][QtCore][QAbstractItemModel] Added the multiData()

And remove the old manual registration code for those operators.
Add some special handling for long/ulong, as these types could be
streamed as a QVariant so far, but are not directly streamable
through QDataStream.
[ChangeLog][QtCore][QMetaType] The QMetaType::registerStreamOperators()
and QMetaType::registerDebugStreamOperator() methods have been
removed. The streaming operators for a type are now automatically
registered together with the type registration. This implies that the
operators should be visible wherever the type is visible and being used.
[ChangeLog][Behavior Incompatible Changes] Because the QDataStream and
QDebug serialization operators are automatically registered with
QMetaType, the declarations of those functions must be present at any
point where the type is used with QMetaType and QVariant.

isNull() would forward to the contained type and check that type's
isNull() method for some of the builtin types. Remove that behavior
and only return true in isNull(), if the variant is invalid, doesn't
contain data or contains a null pointer.
In addition, implement more consistent behavior when constructing
a QVariant using the internal API taking a copy from a void *.
isNull() should return true in both cases. This mainly changes behavior
for some corner cases and when using our internal API.
[ChangeLog][Important Behavior Changes] QVariant::isNull()
no longer returns true when the variant contains an object of some
type with an isNull() method, that returns true for the object;
QVariant::isNull() now only returns true when the variant contains
no object or a null pointer.
