All these TUs relied on transitive includes of qpointer.h, maybe to a
large extent via qevent.h, though, given that qevent.h is more or less
the only public QtBase header that includes qpointer.h, something else
seems to be at play here.
Said qevent.h actually needs QPointer in-name-only, so a forward
declaration would suffice. Prepare for qevent.h dropping the include.
The algorithm I used was:
If the TU mentions 'passiveGrabbers', the name of the QEvent function
that returns QPointers, and the TU doesn't have qpointer.h included
explicitly, include it. That may produce False Positives, but better
safe than sorry. Otherwise, in src/, add an include to all source and
header files which mention QPointer. Exception: if foo.h of a foo.cpp
already includes it, don't include again.

The density of Q_FOREACH uses is high here, too high for this author
to tackle in a short amount of time. But they're concentrated in just
a few TUs, so pick a different strategy:
Mark the whole library with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too). Created QTBUG-115803 to keep track of
this.

To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.
At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.
The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.
In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.
To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

In Qt 6.3, a check for WA_InputMethodEnabled was removed
in QWidget, to support IM queries also for read-only
widgets (7c6e4af48). This caused a regression on iOS, which
made the input panel open for widgets that didn't support
IM at all.
A patch was merged that solved the regression (3b12305575),
but it didn't take the widget attribute into account.
Since not doing so has the potential to cause regressions,
this patch will modify the affected code once more, so that
we instead fall back to test WA_InputMethodEnabled when
ImEnabled is not implemented. This will match closely
to the way ImEnabled was implemented in Qt 6.2.
Since we, with this change, now require that either ImEnabled
or WA_InputMethodEnabled is set, our own input widgets will
fail to support IM text selection when they're read-only, since
they actually don't implement ImEnabled.
This patch will therefore also make sure that we do so.

QGraphicsItems may override itemChange to prevent certain attribute
changes. Overriding ItemSelectedChange this way is explicitly documented
to be allowed.
However QGraphicsScene::clearSelection did not test whether items were
in fact deselected after the call to setSelection, and always cleared
the stored set of selected items.
Fix this by checking the actual selected state of the item as we iterate
over them, and store those items that are still selected in a set that
becomes the new selectedItems set (which will be empty if no item
overrides, which is the default).
Add a test that also checks that clearing the selection emits the
selectionChanged signal correctly (and does not if all selected items
block being deselected).

under each touch point.
In addition, limit the implicit grabbing of each touch point before
sending the event to those cases where we have to: touch pads, and
if the target widget comes from a closest-widget matching. And don't
call the QTouchEvent override of QEvent::setAccepted() on QTouchEvent
instances in QGraphicsView classes, as this will override each event
point's acceptance state.
This way, we can identify which touch points have been accepted after
event delivery, any only implicitly grab those points that were.
Otherwise, touch points not accepted by a proxied widget hierarchy
will still be part of an accepted event, and be grabbed by the
viewport of the QGraphicsView. This would then lead to infinite
recursion when the QGraphicsProxyWidget passes the TouchUpdate event
on to each touch point's grabber.
