Update window flags from QToolBarPrivate::endDrag().

Activate previously #ifdef'ed code which cleared
the Qt::X11BypassWindowManager hint. With the hint
set, the tool bar stays on top and does not get deactivated
along with the application by the WM.

Widgets: be more careful when setting focus on touch release

An application might choose to change focus when receiving mouse/touch
press/move events. This is in conflict with Qt assigning focus on touch
release (QPlatformIntegration::SetFocusOnTouchRelease), since Qt
might then reassign focus to something else.

An example of this is seen with the "frozencolumn" example. Here, when
the user double clicks on a cell, the application creates an 'edit'
widget inside the cell that gets focus. But at soon as the last release
is sent, Qt will change focus to the focus proxy of QScrollArea instead.

This patch will introduce an exception to setting focus on release, so that
we only set focus if we detect that focus didn't change (by the app)
while processing press/move events.

Take ShareOpenGLContexts into account in QOpenGLWindow

While the attribute was originally intended for widgets (QOpenGLWidget,
QQuickWidget) only, we need a way to get multiple QOpenGLWindow instances
whose contexts share with each other.

doc: Clarify \inqmlmodule usage

The \inqmlmodule command only accepts one parameter: the name of the module.
This was producing some confusion, since in qtdeclarative there were some wrong
import statements and it wasn't obvious which command was producing them.
