Rename QDeclarative symbols to QQuick and QQml

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.

+    \ingroup qml-working-with-data
+    \brief Package provides a collection of named items.
+
+    The Package class is used in conjunction with
+    VisualDataModel to enable delegates with a shared context
+    to be provided to multiple views.
+
+    Any item within a Package may be assigned a name via the
+    \l{Package::name}{Package.name} attached property.
+
+    The example below creates a Package containing two named items;
+    \e list and \e grid.  The third element in the package (the \l Rectangle) is parented to whichever
+    delegate it should appear in.  This allows an item to move
+    between views.
+
+    \snippet examples/declarative/modelviews/package/Delegate.qml 0
+
+    These named items are used as the delegates by the two views who
+    reference the special \l{VisualDataModel::parts} property to select
+    a model which provides the chosen delegate.
