Instead of having each winsys implement its own list of callbacks the
list is now just attached directly to the CoglOnscreen using code in
cogl-onscreen.c. The winsys's can invoke this list of callbacks by
calling _cogl_onscreen_notify_swap_buffers(). All of the winsys's
would probably have a very similar implementation for this anyway and
I don't think it makes much sense to try and save the cost of a list
pointer in the CoglOnscreen struct.

Unlike in GObject the type number for a CoglObject is entirely an
internal implementation detail so there is no need to make a GQuark to
make it safe to export out of the library. Instead we can just
directly use a fixed pointer address as the identifier for the type.
This patch makes it use the address of the class struct of the
identifier. This should make it faster to do type checks because it
does not need to call a function every time it wants to get the type
number.

This factors out the CoglOnscreen code from cogl-framebuffer.c so we now
have cogl-onscreen.c, cogl-onscreen.h and cogl-onscreen-private.h.
Notably some of the functions pulled out are currently namespaced as
cogl_framebuffer but we know we are planning on renaming them to be in
the cogl_onscreen namespace; such as cogl_framebuffer_swap_buffers().
