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.

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 af480a2b8b.
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
defines compatible NOP macros within deprecated/cogl-type-casts.h
This patch doesn't look right because now nothing will ever set
clear_clip_dirty = TRUE. Presumably that would mean that if a
rectangle is drawn and then the journal is flushed before the
framebuffer is read, then it would think it could return the clear
color even though it shouldn't.
Perhaps a better approach would be to make a second version of
_cogl_framebuffer_mark_mid_scene that doesn't set the clear_clip_dirty
flag and call that from the journal instead. As this patch was pushed
without review and without first going into the master branch I think
it makes sense to just revert it and apply a new version to master.
This reverts commit 3eb63f67a3.
Leaving the clip bounds untouched means that it will retain the stale value
of whatever it was when we last had a clip; reset it so that it contains the
full framebuffer contents instead.

Add framebuffer methods cogl_framebuffer_[gs]et_depth_write_enabled()
and backend bits to pass the state on to glDepthMask().
This allows us to enable or disable depth writing per-framebuffer, which
if disabled saves us some work in glClear(). When rendering, the flag
is combined with the pipeline's depth writing flag using a logical AND.
Depth writing is enabled by default.

Depending on what version of Mesa you have then eglQueryWaylandBuffer

only forward declare the corresponding type.
The use of wl_buffer has been deprecated and so internally we assume

forward declare wl_resource in case we are building with EGL headers
that still use wl_buffer.

When a pipeline is notified of a change we now make sure to notify all
progends of that change not just the progend directly associated with
that pipeline. A pipeline can have private state associated with it from
multiple progends because descendants will always try and cache state on
ancestors to maximize the chance that the state can later be re-used.
Descendants may be using different progends than the ancestors that they
cache state with.

In the cases where we cache vertex state with an ancestor pipeline (whose
vertex processing state is equivalent) we need to invalidate that state
if that ancestor is later modified.
This conformance test checks this case but currently fails because we
only notify the progend directly associated with the pipeline being
changed.
In this case the pipeline can be using a different progend to the
ancestor which it is caching state with so when the ancestor is changed
it needs to notify all the progends that they may need to clear their
private state.

This makes a start on clearly factoring the deprecated code of core Cogl
into a deprecated/ directory. Ideally we want to get to the point where
all code here can be re-worked in terms of the public 2.0 api so that it
can be kept indefinitely for cogl 1.x api compatibility without
cluttering the core code base itself. If we can do this then we can
avoid maintaining the Cogl 1.x branches in parallel with master which
would reduce the maintenance effort.
