This means CoglContext is now also introspected, although its
constructor and some getters are skipped to avoid having to expose even
more types. This makes it possible to create pipelines using Javascript.

They have been deprecated for a long time, and all their uses in clutter
and mutter has been removed. This also removes some no longer needed
legacy state tracking, as they were only ever excercised in certain
circumstances when there was sources (pipelines or materials) on the now
removed source stack.

This means cogl_set_source_color*() that switches to the opaque or
blending pipeline, or cogl_source_set_texture() which switches to the
texture pipeline.
Left is the opaque pipeline, as it is still used to compare other
pipelines to check whether they are opaque or not, and as the default
pipeline still pushed to the source stack during initialization.

Change the warp modes test to sanity check CoglPrimitive based polygon
drawing instead of cogl_polygon(). This removes some checks, as
cogl_polygon() has explicitly documented special behaviour for automatic
wrap modes, which CoglPrimitive does not.

When painting, actors rely on semi global state tracked by the state to
get various things needed for painting, such as the current draw
framebuffer. Having state hidden in such ways can be very deceiving as
it's hard to follow changes spread out, and adding more and more state
that should be tracked during a paint gets annoying as they will not
change in isolation but one by one in their own places. To do this
better, introduce a paint context that is passed along in paint calls
that contains the necessary state needed during painting.
The paint context implements a framebuffer stack just as Cogl works,
which is currently needed for offscreen rendering used by clutter.
The same context is passed around for paint nodes, contents and effects
as well.
In this commit, the context is only introduced, but not used. It aims to
replace the Cogl framebuffer stack, and will allow actors to know what
view it is currently painted on.

This is inspired by 98892391d7 where the usage of
`g_signal_handler_disconnect()` without resetting the corresponding
handler id later resulted in a bug. Using `g_clear_signal_handler()`
makes sure we avoid similar bugs and is almost always the better
alternative. We use it for new code, let's clean up the old code to
also use it.
A further benefit is that it can get called even if the passed id is
0, allowing us to remove a lot of now unnessecary checks, and the fact
that `g_clear_signal_handler()` checks for the right type size, forcing us
to clean up all places where we used `guint` instead of `gulong`.
No functional changes intended here and all changes should be trivial,
thus bundled in one big commit.

The function create_texture() in test-wrap-modes.c takes a
TestUtilsTextureFlags. However a CoglTextureFlags is passed instead
in two calls. As the enums are identical this patch changes it to
use the TestUtils type.
The enum definitions:
typedef enum
{
COGL_TEXTURE_NONE = 0,
COGL_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
COGL_TEXTURE_NO_SLICING = 1 << 1,
COGL_TEXTURE_NO_ATLAS = 1 << 2
} CoglTextureFlags;
typedef enum
{
TEST_UTILS_TEXTURE_NONE = 0,
TEST_UTILS_TEXTURE_NO_AUTO_MIPMAP = 1 << 0,
TEST_UTILS_TEXTURE_NO_SLICING = 1 << 1,
TEST_UTILS_TEXTURE_NO_ATLAS = 1 << 2
} TestUtilsTextureFlags;

In _cogl_offscreen_gl_allocate we only want to perform certain actions if
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL is not set in create_flags.
We perfrom this check with:
if (!offscreen->create_flags & COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL)
which is not correct as we negate the create_flags before the bitwise &.
It happens to work as intended though, as CoglOffscreenFlags only has one
element, and that element has the value 1. If the flag is not set then the
nagation of create_flags is true and the bitwise and with the element value
is true as well.
If any flag is set then the negation will give 0 and the bitwise & will be
false.
So while it works correctly it is fragile as either additional flags or a
change in the enum element value will break this check. This patch makes
things a bit more safe by adding parentheses to let the bitwise & happen
before the negation.
Definition of the enum:
typedef enum
{
COGL_OFFSCREEN_DISABLE_DEPTH_AND_STENCIL = 1
} CoglOffscreenFlags;

cogl_pipeline_get_front_face_winding() is supposed to return a CoglWinding. It
takes a CoglPipeline as argument and does the following input validation:
g_return_val_if_fail (cogl_is_pipeline (pipeline),
COGL_PIPELINE_CULL_FACE_MODE_NONE);
The returned COGL_PIPELINE_CULL_FACE_MODE_NONE is not a winding.
The function was added with this check 8 years ago in
5369b3c601
I do not see any of the two options in the CoglWinding as particularly good
choice for a return value on bad input, but let's go with
COGL_WINDING_CLOCKWISE as that is equivalent with the behavior for all
these years.
Definitions of the two enums:
typedef enum
{
COGL_WINDING_CLOCKWISE,
COGL_WINDING_COUNTER_CLOCKWISE
} CoglWinding;
typedef enum
{
COGL_PIPELINE_CULL_FACE_MODE_NONE,
COGL_PIPELINE_CULL_FACE_MODE_FRONT,
COGL_PIPELINE_CULL_FACE_MODE_BACK,
COGL_PIPELINE_CULL_FACE_MODE_BOTH
} CoglPipelineCullFaceMode;

As noted in <cogl-texture-2d-gl.h> (now also removed), this is for
allowing external GL callers to promote one of their textures to a
CoglTexture. We aren't doing that and don't want to start.
