A texture based node without a valid texture is not allowed,
as the material and the renderer will only tolerate
well-formed nodes. If a node is missing any part of its material
state it should not be in the scene graph in the first place.

Because of an "optimization" in QSGDefaultImageNode::setTexture
and QSGSimpleTextureNode::setTexture, we must temporarily set
the texture to 0 to ensure that it gets updated properly. This
temporarily puts the node into an invalid state which can lead
to crashes when QSGNode::markDirty() reaches the renderer.

This define is quite useful for debugging scene graph internals, but
it is disabled by default to conserve memory.

For clarity, I renamed the define to QSG_RUNTIME_DESCRIPTION.

This commit introduces the enum TextureCoordinatesTransformFlag and
corresponding QFlags OR combination TextureCoordinatesTransformMode.
This enum is used to control the orientation of texture coordinates
relative to window/item coordinates.

The common use case addressed by this commit is when rendering to a
texture via an FBO using some 3rd party OpenGL library. Some libraries
do not offer a way to orient the rendered output which results in the
texture being displayed upside down when used in conjunction with
QSGSimpleTextureNode.

There are a number of possible solutions to this:

1 Mirror the item by scaling by -1 in the y-direction in QML document

2 Use a custom material (shader) that transforms texture coordinates
  in GLSL

3 Generate texture coordinates differently

This commit opts for approach 3. Approach 1 is ugly and visible to the
end user and also causes more work when other transformations interact
with the necessary scaling. Approach 2 has a performance cost in both
switching material (shader) and also in additional per-vertex or per-
fragment operations. The chosen approach hides it from the end user
and has zero runtime cost delta compared to any other textured quad.

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...
