updateAncestorFlags was not reseting the flags if you change the parent
that have for instance itemsClipChildrenToShape to a new one that
doesn't have that flag.

Forwarding the ignoreOpacity flag to children in QGraphicsItemPrivate::fullUpdateHelper.
This is a complementary fix to task 252913, partly fixed in commit 2e3a5ea44...

When setVisible() is called on a QGraphicsItem, if the parent of that
item was hidden, the child shouldn't be actually shown.

QGraphicsItem::deviceTransform() returns the item-to-device transform,
provided with the device-to-scene transform, and combining it with the
item's scene transform. This function is meant to handle items that
enable ItemIgnoresTransformations, but it happened to not work properly
for items that _don't_ enable that flag. Unfortunately this bug is
hard to work around for users from the outside, as it requires you to
check if the item or any ancestor enables ItemIgnoresTransformations.
The fix also removes unnecessary branchs inside QGV so that we use the
same function for all items.

The problem was that we discarded update requests for fully
transparent items, which is correct, but we even did that
when the update was issued from QGraphicsItem::setOpacity.
We don't have to, and shouldn't, consider the opacity in
that case. Whenever we reach the fullUpdateHelper call in
setOpacity it means we have to do an update regardless of
the current opacity (oldOpacity was not 0.0 if the
currentOpacity is 0.0).
Auto-test included.

This fixes a bug in 4.5.0 where cached items that call update() after
they have been moved or transformed failed to get a call to paint(),
so the last cache image was used to draw. The easiest way to reproduce
this bug is in the Elastic Nodes example. If you press, wait, then
release, the nodes will consistently move to sunken state, then back
to normal state. But if you click quickly while moving the mouse, the
nodes will stay sunken.
The bug was that the item was marked as dirty as a result of being moved,
and when the mouse button was released, the node item's call to update()
was discarded, as the item was "already dirty".
The fix is to allow invalidation of the cache even if the item is
marked as dirty.

Previously we were calling two times itemChange on the parent to give
QGraphicsItem::ItemChildAddedChange. We don't need that. One is enough.

Each version of Qt has its own set of autotests, therefore
preprocessor directives relating to obsolete QT_VERSION's
are not necessary.

same.
updateBoudingRect update the item only if the boundingRect change
but if we have 123 as an initial text and then we set 321 as the new
text, then nothing happen because the rect is the same.
In case the boundingRect change then we call update 2 times but
the item is already dirty so the second call will just return.

Regression caused by optimizations in QGraphicsItem and QGraphicsScene.
The changes in QGraphicsItem fix bugs in QGraphicsItem::mapToParent
functions, which did the translation before applying the transformation,
instead of the other way (transform, then translate). This bug caused
almost all mapToParent and mapRectToParent functions to behave wrongly.
Unfortunately the new helper functions in QGraphicsScene for discovering
items made use of these functions, which introduced a regression. Fixing
these functions also fixes item discovery.
The other part of this change fixes a regression caused by c1909321,
which luckily happened after 4.5.0 and never saw the light of day. The
fix is to also invalidate the cached clip path even if there is no scene,
which is necessary if you build your scene graph outside the scene, and
finish off by adding the root item to the scene.

The problem here is that we are filling the sceneEventFilters map
when we install evenfilter but we never remove the references of an
item if it has been removed from the scene or deleted. The deletion can
keep stale pointers into the map and a crash can happen.
