Comparing pointers that do not point into the same array using
operator< is UB. You need to use std::less<>.
The QOrderedMutexLocker ctor already used std::less to compare
pointers, but the static relock() function was not fixed.

Previously when a new QOpenGLFramebufferObject was bound, the
QOpenGLContextPrivate::qgl_current_fbo member was also updated to point
to this new object.
But if a user called QOpenGLFramebufferObject::bindDefault(),
qgl_current_fbo was not unset, meaning that if the FBO object would be
deleted at some point, qgl_current_fbo would be a dangling pointer.
This patch makes sure to clear the value of qgl_current_fbo when
bindDefault() is called. It is cleared, and not set to point to another
object because the default platform OpenGL FBO is not backed by a
QOpenGLFramebufferObject.

The old code fell through into from the CE_RubberBand case into the
CE_SizeGrip case if the cast of the the QStyleOption to a

Quite obviously, the drawing of a rubber band was requested by the
caller, drawing a size grip instead must be considered a bug,
regardless of any additional guards employed by the size grip case.
So, fix by removing the conditional return in the success case and
adding an unconditional break. The function ends after the switch,
and all other cases also break instead of return, so consider the
switch from return to break a contribution to the internal consistency
of the function.

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.

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
