A first step towards abandoning the CoglObject type system: convert
CoglFramebuffer, CoglOffscreen and CoglOnscreen into GObjects.
CoglFramebuffer is turned into an abstract GObject, while the two others
are currently final. The "winsys" and "platform" are still sprinkled
'void *' in the the non-abstract type instances however.

As we will start adding support for more pixel formats, we will need to
define a notion of planes. This commit doesn't make any functional
change, but starts adding the idea of pixel formats and how they (at
this point only theoretically) can have multple planes.
Since a lot of code in Mutter assumes we only get to deal with single
plane pixel formats, this commit also adds assertions and if-checks to
make sure we don't accidentally try something that doesn't make sense.

The function will be used in copying from a primary GPU framebuffer to a
secondary GPU framebuffer using the primary GPU specifically when the
secondary GPU is not render-capable.
To allow falling back in case glBlitFramebuffer cannot be used, add boolean
return value, and GError argument for debugging purposes.

Depends on: "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
As a possible ANGLE implementation is not longer limiting the pixel format
matching, lift the requirement of having the same pixel format.
We still cannot do a premult <-> non-premult conversion during a blit, so guard
against that.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer if the formats do not
match exactly.

This basically reverts commit 54735dec, which tried to avoid the
GLib-defined types in favor the standard C ones. One exception to this
is the bool type, for which the commit introduces a new type CoglBool.
Let's just get rid of this type in favor of having consistency with the
GLib types. Note by the way that neither CoglBool nor gboolean (which
has a size of `int`) are completely compatible with bool (size `char`).

In cogl use cogl-config.h and in clutter use clutter-build-config.h. We
can't use clutter-config.h in clutter because its already used and
installed.
