Add the capability flags to the extended mouse events. Otherwise it is
not possible to tell if the velocity is valid.

While the original version is fine if velocity is guaranteed to be
available whenever QT_TRANSLATE_TOUCH_TO_MOUSE is set, some platform
and driver combinations, e.g.  the evdevtouch plugin that comes with
Qt, do not provide velocity data in touch events. The touch-only mode
of QML may be very useful in these cases too, we just need to fall
back to the built-in velocity calculation.

Allowing the canvas to deal with mouse event emulation provides
a couple of advantages: 1. touches outside a reactive area can

specifically velocity in this case.

What was traditionally the QQuickRenderLoop which was used
to support one QQuickCanvas instance has now grown to support
multiple QQuickCanvas instances and is now called
QQuickWindowManager, of which there are two implementations.

QQuickRenderThreadSingleContextWindowManager:
One QSGContext and one OpenGL context is being used to draw
all the windows and we alternate between which surface the gl
context is bound to. This implementation relies on that
swap does not block, but that the graphics pipeline is
vsynced and will eventually block as the buffer queue is
filled up. This is the behavior we get on Mac OS X and
Wayland. The benefit of this implementation is that we have
vsync'ed animations, and the synchronizaiton between GUI and
render thread is simple. (well, simple relative to the
alternative, that is).

QQuickTrivialWindowManager:
One QSGContext and one OpenGL context is being used on the GUI
thread. Animations are ticked from a timer. Performance of this
implementation will deteriorate if the driver is using blocking
swap.

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.
