KItemListViewLayouter uses a KItemListSizeHintResolver to find out how
much space the items will need in the view.
Before this commit, the size hint resolver object could be changed at
runtime, and it could also be null. However, we never made use of these
possibilities, so all the code that checks if m_sizeHintResolver is
null is actually not needed at all.
Moreover, clear the entire hash if items are added or removed.
This saves time and memory when loading a directory, and it fixes
problems that might occur if the model is in an inconsistent state, such
as crashes that can happen when we try to remove individual items from
m_items.

The problem was that we restored the URL of the right view while the
left one is still active. When we received the signal
urlChanged(KUrl& url) from the right URL navigator, we then set the URL
of the active (i.e., left) view to 'url', such that both views showed
the same URL.

This commit works around the problem that KDirLister may not provide a
"rootItem" for some kioslaves by setting up a KFileItem with the view
URL and using this to find out if the URL is writable.

The pointer to QThread object is stored in a global variable, and each
view increments/decrements a reference count when it starts/stops using
the thread. If this thread reaches zero, the thread is stopped.
Note that we cannot just use a smart pointer, like QSharedPointer, to
manage the thread, because we must make sure that the thread is not
running any more before the QThread is deleted.

Showing an error message, makes no sense in this case - the user can see it when all items are "unversioned".
The plugins still have the ability to show error/warning messages on real errors. (and only where it makes sense ;)

and in VersionControlObserver::slotThreadFinished().
So we get O(n) complexity instead of O(n*logn), and O(1) memory instead of O(n).
Thanks to Thiago Macieira for providing this information.

The speed up is really small, but theses changes are mostly straightforward and make the code a bit nicer - break
the KStandardItemListWidgetInformant::itemSizeHint beast into three smaller functions.

If loading a preview takes long, it was possible before this commit
that a preview for a new item was requested before the first preview
was shown. In that case, there was a race condition, and the first
preview to arrive stayed in the Information Panel.
This commit fixes this by keeping a pointer to the preview job and
killing it before starting a new one.

KFileItemModel allows to find out the index of a KFileItem with its
index(const KFileItem&) method. Calling this method is not extremely
expensive, but it's also not free (it looks up the URL of the KFileItem
in a QHash, i.e., it has to call qHash(QString) for the full URL).
In KFileItemModelRolesUpdater, we sometimes converted the known index to
a KFileItem and then back to an index in applyResolvedRoles(KFileItem).
This patch fixes this by modifying applyResolvedRoles such that it takes
the index directly as its argument.

It is not necessary to save the position of each item as a QPointF
because all items in a row will have the same y-coordinate, and all
items in a column will have the same x-coordinate. Therefore, we can
reduce the number of doubles that we store from
(number of items) * 2
to
(number of rows) + (number of colums)
which is at least 50% less.

The problem was that the loop in KFileItemModel::createMimeData() which
is supposed to find out if any parent of an item has been added to the
QMimeData already (because it is not necessary to add the item in that
case) did not loop through the parents of the item, but incorrectly
replaced the local variable 'itemData' by its parent.

The test verifies that creating the mime data for a child of an expanced
folder does not cause a crash. The regression happenened in the master
branch, but it doesn't hurt to have the test also in KDE/4.12.

This fixes the problem that the new file name is not shown in the view
