This reverts commit 2556bfdab42dc0aefb34bb7cf304063c7db0ff00.
This is no longer necessary, as there are now no users of this
functionality in other modules.

In Qt Quick Controls 2, we plan on using positioners to layout an icon
next to text in a button, for example.
Consider the following example:
AbstractButton {
id: button
text: "Button"
contentItem: Row {
Text {
text: button.text
width: parent.width
}
}
background: Rectangle {
radius: 5
color: "lightsteelblue"
opacity: button.pressed ? 1.0 : 0.8
}
}
In Qt Quick Controls 2, implicit size propagates "up" from the
delegates/building blocks to the control, whereas explicit size
propagates "down" from the control to the delegates/building blocks.
Providing a reasonable implicit size is important to make controls
behave well in layouts, etc., and the internal building blocks must
follow the size of the control to retain sensible looks when a control
is resized.
In the example above, contentItem needs to have a "natural" (implicit)
size representing the ideal fit of the content, but it needs to respect
the explicitly provided size from the control too.
With the current behavior, as the explicit width of the Row is 0, the
Text item (via the width binding) sets explicit width to 0, and Row
uses that explicit width rather than the implicit width, thus, Row here
will have an implicit width of 0, which is not what the control wants.
This patch:
- Allows subclasses of positioners to set
QQuickBasePositionerPrivate::useImplicitSize to true in order to tell
positioners to use implicit size rather than explicit size. This is
not exposed as public API, as this behavior is typically not
something desirable in the positioners themselves. For example,
Row { Rectangle { width: 100; height: 100 } } would have an implicit
size of 0, as Rectangle has no implicit size.
- Adds QQuickImplicitRow and QQuickImplicitGrid, which are private
subclasses of their respective positioners that simply set
useImplicitSize to true in their constructors.
- Exports the wrappers privately so that they can be registered by
other modules as QML types.

This change introduces two new properties, horizontalItemAlignment and verticalItemAlignment to a
Grid element. This gives the user the possibility to align the items.

Fix positioners to apply a "populate" transition for initially added
items. This is consistent with ListView and GridView and also fixes the
behaviour from QtQuick 1.x where the positioners were instead running
the "move" transition for initially added items.

Symbols beginning with QDeclarative are already exported
by the quick1 module.
Users can apply the bin/rename-qtdeclarative-symbols.sh
script to modify client code using the previous names of the
renamed symbols.
