There used to be a function called cogl_clip_stack_save in the public
API which was used when temporarily switching to an offscreen buffer
to save the clip state. This is no longer necessary because each
framebuffer has its own clip stack anyway so the function was removed
in master. However the code to maintain the stack of stacks was
retained. This patch removes it in an effort to simplify the code.
On the 1.18 branch this function is deprecated and the documentation
says that it does nothing. However that is incorrect because it does
actually the push clip stack. I think it would be safe to backport
this patch to the 1.18 branch and actually make it do nothing like it
is documented to do.

This patch has some extra changes while backporting to the 1.18
branch. Here the cogl-clip-state file still contained some deprecated
functions. Instead of deleting the file completely it has been moved
to the deprecated folder. The declarations for this functions have
been moved from cogl1-context.h to a new deprecated/cogl-clip-state.h
header.

Dispose() may be called more than once, so calling g_free directly
on the device name is unsafe. Instead, use g_clear_pointer() to
make sure we don't attempt to free the memory again.

Adds cogl_wayland_texture_set_region_from_shm_buffer which is a
convenience wrapper around cogl_texture_set_region but it uses the
correct format to copy the data from a Wayland SHM buffer. This will
typically be used by compositors to update the texture for a surface
when an SHM buffer is attached. The ordering of the arguments is based
on cogl_texture_set_region_from_bitmap.
Based on a patch by Jasper St. Pierre.

This patch was accidentally added before it had any review and without
first going through master. Master now has a replacement patch with
some modifications. That will be cherry-picked to the 1.18 branch in a
subsequent commit.
This reverts commit af480a2b8b5450148ca4b969eec90ee330d5fd12.
Previously the private feature flags were stored in an enum and we
already had 31 flags. Adding the 32nd flag would presumably make it
add -2³¹ as one of the values which might cause problems. To avoid
this we'll just use an fixed-size array of longs and use indices for
the enum values like we do for the public features.
A slight complication with this is in the CoglDriverDescription where
we were previously using a static intialised value to describe the set
of features that the driver supports. We can't easily do this with the
flags array so instead the features are stored in a fixed-size array
of indices.

This fixes the build with --enable-introspection. I'm not sure why
g-ir-scanner seems to parse all public headers in isolation instead of
being able take a more limited list of top-level public headers and
automatically parse all necessary #include directives but this means we
have to special case how we define and undefine __COGL_H_INSIDE__ to
subvert the guards we have in place for detecting misuse of the headers.

This declares the interface types CoglFramebuffer, CoglBuffer,
CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when
including the public cogl.h header so that users don't have to use lots
of C type casts between instance types and interface types.
This also removes all of the COGL_XYZ() type cast macros since they do
nothing more than compile time type casting but it's less readable if
you haven't seen that coding pattern before.
Unlike with gobject based apis that use per-type macros for casting and
performing runtime type checking we instead prefer to do our runtime
type checking internally within the front-end public apis when objects
are passed into Cogl. This greatly reduces the verbosity for users of
the api and may help reduce the chance of excessive runtime type
checking that can sometimes be a problem.

Since we can't break the 1.x api this version of the patch actually

When support for implicit animation of actor position was added,
the optimization for not queueing when allocating an actor back
to the same location was lost. This optimization is important
since when we are hierarchically allocating down from the top of
the stage we constantly reallocate the actors at the top of the
hierarchy back to the same place.

When the source actor potentially changes size, that shouldn't
necessarily result in the target actor being redrawn - it should
be like when a child of a container is reallocated due to changes
in its siblings or parent - it should redraw only to the extent
that it is moved and resized. Privately export an internal function
from clutter-actor.c to allow getting this right.

Since subsurfaces won't have toplevel MetaWindowActors, we need to
use MetaSurfaceActor instead. These are embedded in the MetaWindowActor,
just like MetaShapedTexture was (in fact, MetaSurfaceActor now contains
a MetaShapedTexture)
Make MetaWindowActor chain up to the generic default MetaCullable
implementation, and remove the helper methods for MetaSurfaceActor
and MetaShapedTexture.
Instead of hardcoded knowledge of certain classes in MetaWindowGroup,
create a generic interface that all actors can implement to get parts of
their regions culled out during redraw, without needing any special
knowledge of how to handle a specific actor.
The names now are a bit suspect. MetaBackgroundGroup is a simple
MetaCullable that knows how to cull children, and MetaWindowGroup is the
"toplevel" cullable that computes the initial two regions. A future
cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so
that we only have a generic MetaSimpleCullable, and move the "toplevel"
cullability to be a MetaCullableToplevel.
