Say hello to QtQuick module

This change moves the QtQuick 2 types and C++ API (including
SceneGraph) to a new module (AKA library), QtQuick.

99% of this change is moving files from src/declarative to
src/quick, and from tests/auto/declarative to
tests/auto/qtquick2.

The loading of QtQuick 2 ("import QtQuick 2.0") is now delegated to
a plugin, src/imports/qtquick2, just like it's done for QtQuick 1.

All tools, examples, and tests that use QtQuick C++ API have gotten
"QT += quick" or "QT += quick-private" added to their .pro file.

A few additional internal QtDeclarative classes had to be exported
(via Q_DECLARATIVE_PRIVATE_EXPORT) since they're needed by the
QtQuick 2 implementation.

The old header locations (e.g. QtDeclarative/qquickitem.h) will
still be supported for some time, but will produce compile-time
warnings. (To avoid the QtQuick implementation using the
compatibility headers (since QtDeclarative's includepath comes
first), a few include statements were modified, e.g. from
"#include <qsgnode.h>" to "#include <QtQuick/qsgnode.h>".)

There's a change in qtbase that automatically adds QtQuick to the
module list if QtDeclarative is used. Together with the compatibility
headers, this should help reduce the migration pain for existing
projects.

In theory, simply getting an existing QtDeclarative-based project
to compile and link shouldn't require any changes for now -- but
porting to the new scheme is of course recommended, and will
eventually become mandatory.

+    \qmlproperty bool QtQuick2::Animation::running
+    This property holds whether the animation is currently running.
+
+    The \c running property can be set to declaratively control whether or not
+    an animation is running.  The following example will animate a rectangle
+    whenever the \l MouseArea is pressed.
+
+    \code
+    Rectangle {
+        width: 100; height: 100

+        }
+        MouseArea { id: myMouse }
+    }
+    \endcode
+
+    Likewise, the \c running property can be read to determine if the animation
+    is running.  In the following example the text element will indicate whether
+    or not the animation is running.
+
+    \code
+    NumberAnimation { id: myAnimation }
+    Text { text: myAnimation.running ? "Animation is running" : "Animation is not running" }
+    \endcode
+
+    Animations can also be started and stopped imperatively from JavaScript
+    using the \c start() and \c stop() methods.
+
+    By default, animations are not running. Though, when the animations are assigned to properties,
+    as property value sources using the \e on syntax, they are set to running by default.

+    \inherits Animation
+    \brief The PropertyAction element allows immediate property changes during animation.
+
+    PropertyAction is used to specify an immediate property change during an
+    animation. The property change is not animated.
+
+    It is useful for setting non-animated property values during an animation.
+
+    For example, here is a SequentialAnimation that sets the image's
+    \l {Image::}{smooth} property to \c true, animates the width of the image,
+    then sets \l {Image::}{smooth} back to \c false:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml standalone
+
+    PropertyAction is also useful for setting the exact point at which a property
+    change should occur during a \l Transition. For example, if PropertyChanges
+    was used in a \l State to rotate an item around a particular
+    \l {Item::}{transformOrigin}, it might be implemented like this:
+
+    \snippet doc/src/snippets/declarative/propertyaction.qml transition
+
+    However, with this code, the \c transformOrigin is not set until \e after
+    the animation, as a \l State is taken to define the values at the \e end of
+    a transition. The animation would rotate at the default \c transformOrigin,
+    then jump to \c Item.BottomRight. To fix this, insert a PropertyAction
+    before the RotationAnimation begins:
+
+    \snippet doc/src/snippets/declarative/propertyaction-sequential.qml sequential
+
+    This immediately sets the \c transformOrigin property to the value defined
+    in the end state of the \l Transition (i.e. the value defined in the
+    PropertyAction object) so that the rotation animation begins with the
+    correct transform origin.

+    \brief The RotationAnimation element animates changes in rotation values.
+
+    RotationAnimation is a specialized PropertyAnimation that gives control
+    over the direction of rotation during an animation.
+
+    By default, it rotates in the direction
+    of the numerical change; a rotation from 0 to 240 will rotate 240 degrees
+    clockwise, while a rotation from 240 to 0 will rotate 240 degrees
+    counterclockwise. The \l direction property can be set to specify the
+    direction in which the rotation should occur.
+
+    In the following example we use RotationAnimation to animate the rotation
+    between states via the shortest path:
+
+    \snippet doc/src/snippets/declarative/rotationanimation.qml 0
+
+    Notice the RotationAnimation did not need to set a \l target
+    value. As a convenience, when used in a transition, RotationAnimation will rotate all
+    properties named "rotation" or "angle". You can override this by providing
+    your own properties via \l {PropertyAnimation::properties}{properties} or
+    \l {PropertyAnimation::property}{property}.
+
+    Also, note the \l Rectangle will be rotated around its default
+    \l {Item::}{transformOrigin} (which is \c Item.Center). To use a different
+    transform origin, set the origin in the PropertyChanges object and apply
+    the change at the start of the animation using PropertyAction. See the
+    PropertyAction documentation for more details.
+
+    Like any other animation element, a RotationAnimation can be applied in a
+    number of ways, including transitions, behaviors and property value
+    sources. The \l {QML Animation and Transitions} documentation shows a
+    variety of methods for creating animations.

+    \brief The PropertyAnimation element animates changes in property values.
+
+    PropertyAnimation provides a way to animate changes to a property's value.
+
+    It can be used to define animations in a number of ways:
+
+    \list
+    \o In a \l Transition
+
+    For example, to animate any objects that have changed their \c x or \c y properties
+    as a result of a state change, using an \c InOutQuad easing curve:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml transition
+
+
+    \o In a \l Behavior
+
+    For example, to animate all changes to a rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml behavior
+
+
+    \o As a property value source
+
+    For example, to repeatedly animate the rectangle's \c x property:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml propertyvaluesource
+
+
+    \o In a signal handler
+
+    For example, to fade out \c theObject when clicked:
+    \qml
+    MouseArea {
+        anchors.fill: theObject
+        onClicked: PropertyAnimation { target: theObject; property: "opacity"; to: 0 }
+    }
+    \endqml
+
+    \o Standalone
+
+    For example, to animate \c rect's \c width property over 500ms, from its current width to 30:
+
+    \snippet doc/src/snippets/declarative/propertyanimation.qml standalone
+
+    \endlist
+
+    Depending on how the animation is used, the set of properties normally used will be
+    different. For more information see the individual property documentation, as well
+    as the \l{QML Animation and Transitions} introduction.
+
+    Note that PropertyAnimation inherits the abstract \l Animation element.
+    This includes additional properties and methods for controlling the animation.

+
+    These properties are used as a set to determine which properties should be animated.
+    The singular and plural forms are functionally identical, e.g.
+    \qml
+    NumberAnimation { target: theItem; property: "x"; to: 500 }

+    NumberAnimation { targets: theItem; properties: "x"; to: 500 }
+    \endqml
+    The singular forms are slightly optimized, so if you do have only a single target/property
+    to animate you should try to use them.
+
+    The \c targets property allows multiple targets to be set. For example, this animates the

+    \o When used in a transition, a property animation is assumed to match \e all targets
