QGLShader and QGLShaderProgram used to delete the GL object id
in the wrong context. But fixing this means we must keep track of
when contexts are destroyed so that we don't try to access a
context from a shader if it goes away. We also need to transfer
ownership from one context to another when they are shared.
This change introduces QGLSharedResourceGuard, which keeps track
of a context and a GL object identifier. When the context goes
away, ownership is passed to a shared context. When there are
no more shared contexts, the identifier automatically zeroes.

This is the last patch in the QGLPaintDevice series. Although previous
patches have not been reviewed individually, Samuel's reviewed
QGLPaintDevice API and all the changes as the code stands with this
patch.

This patch also refactors QGL2PaintEngineEx::ensureActive() and the
logic which handles multiple paint engines rendering to the same
QGLContext. In a nut-shell:
* QGLPaintDevice::beginPaint() stores the currently bound FBO
* QGLPaintDevice::ensureActiveTarget() makes sure that GL rendering will
end up in the paint device (I.e. the right context is current and the
right FBO is bound). If a different context or FBO was bound, it is
_not_ remembered.
* QGLPaintDevice::endPaint() restores whatever FBO was bound when
beginPaint() was called.
This logic allows interleaved painter rendering to multiple FBOs and
contexts to work as expected. It also allows a stacked begin/end to work
properly when it's mixed with native GL rendering (as far as current
render target is concerened. GL state clobbering is obviously a
different topic).
QGLPaintDevice::context() also had to be made virtual as there's no good
place to call setContext. This might be possible to change in the future
though.
Finally, to make this work, QGLFramebufferObjectPrivate had to be moved
into it's own private header.

This patch adds a new abstract base class which inherits from
QPaintDevice called QGLPaintDevice. This base class will contain
everything the GL paint engines need to know about the surface they are
drawing onto. As such, new surfaces can be targeted by the GL paint
engines without having to modify QtOpenGL. This is very useful for
plugins, specifically QGraphicsSystem plugins.
To unify things a little, the GL paint engines will use the same
QGLPaintDevice API to render into existing target surfaces (QGLWidget,
QGLPixelBuffer & QGLFrameBufferObject). Ideally we'd make QGLPaintDevice
a common ancestor for these surfaces, but obviously that wil break B/C.
This patch only implements QGLWidget using the new interface. Rendering
to other surfaces will be fixed in following patches.

Some applications that uses a mix of OpenGL and QPainter code may
not work correctly with the new GL 2 engine (e.g. the composition demo).
The same is most likely also true for user apps, therefore we need
a way to enforce the usage of the old GL 1 engine for the sake of
compatibility.

QGLFormat was being deep-copied many times per frame because of
code like this:
if (context()->format().doubleBuffer()) { ...
This change modifies QGLFormat to use implicit sharing to reduce
the overhead of the above type of checks.

I added a QGLContextResource class which can be used internally in Qt
for sharing resources between contexts. The QGLContextResource is a
hash map where the context is used as 'key', and the resource is the
'value'. All the sharing contexts point to the same resource, and the
resource is automatically deleted when it is not referenced any more.
Now, the shader manager uses the QGLContextResource class.
I also added a pointer to a struct in the QGLContextPrivate class. The
struct is shared between all the sharing contexts and is deleted
automatically. Currently, the struct only contains the resolved OpenGL
function pointers.
The shared context register code has been simplified.

Now there's only a copy of the texture glyph cache in graphics memory,
avoiding the system memory copy that we used earlier. In addition the
texture will use the GL_ALPHA texture format when possible, making it
consume less graphics memory as well.

A multisample FBO is used for rendering, and is then blitted onto a
non-multisample FBO dynamically bound to the relevant texture.
