You can place the export macros in the namespace declarations on ELF
systems and that will apply to all declarations inside that scope. If a
namespace is exported like that, then we should mark it for versioning
too.
Note that the exporting doesn't happen for declarations in other scopes
of the same namespace, even though the findclasslist.pl script will mark
everything in that namespace. This should not be a problem.

Before commit f1e9076809, mousePressEvent
called the virtual method setSelection(const QRect&, SelectionFlags)
with the 1x1 rectangle which contains only the clicked QPoint, unless
the SelectionFlag "Current" was set because Shift was pressed during
the mouse press.
Since that commit, the behavior has been changed such that the
rectangle is the one that is spanned by the center of the clicked item
and the clicked pixel. In theory, the result should be the same (i.e.,
only the clicked item should be selected), but
* the code path in QListView::setSelection for 1x1 QRects is more
efficient, and
* using a larger QRect can cause problems with custom views, see the
comments in QTBUG-18009
This commit ensures that the 1x1 QRect is used again, unless the
SelectionFlag "Current" is used.

Unlike layouts and spacer items, a QWidget is-not-a QLayoutItem.
QWidgetItem simply wraps the QWidget, so in QFormLayout::setWidget(),
we allocate a widget item for the widget passed, and hand that down
to Private::setItem() for adding to the various data structures.
Private::setItem() has a bunch of guard clauses, though, that return
without deleting the item.
A test triggered this code path and made asan complain.
This is just one part of a larger problem: QFormLayout::setLayout()
normally takes ownership of the layout passed, because QLayouts own
their QLayoutItems, and QLayout is-a QLayoutItem. But setLayout()
fails to live up to the owner role when it fails to add a layout,
and there's no easy way for the API user to check for success.
A fix for this breaks tst_qformlayout, and while those checks that
break deserve to be broken, I'll refrain from proposing the larger
fix for 5.6 LTS, but will propose it for 5.8 or 5.9 instead.
This fix here only fixes the leak in setWidget() by adding a bool
return to Private::setItem() informing Private::setWidget() of the
need to manually delete the item it allocated for the widget.

In some cases, when QNetworkReply::encrypted is emitted,
QNetworkReply::sslConfiguration is not yet initialized, in particular
certificate chain is empty, which breaks the documented usage of
'encrypted' to perform additional checks on certificate chain.
It looks to be caused by the fact that QHttpNetworkReply is originally
associated with 0th QHttpNetworkConnectionChannel, and this association
is not updated if HTTP pipelining is not used. Therefore, a reply on
channel >0 might arrive before reply on channel 0, and then using ssl
configuration from channel 0, which not made it through handshake, is
not usable.
