f1f1e876f1 doc: Fix the remaining warning around the depth state
Various changes have led to the current, separate from the pipeline,
depth state, this commit fixes the remaining waring around that.

4f6fe6f0e2 Fixes for --disable-glib
This fixes some problems which were stopping --disable-glib from
working properly:

• A lot of the public headers were including glib.h. This shouldn't be
  necessary because the API doesn't expose any glib types. Otherwise
  any apps would require glib in order to get the header.

• The public headers were using G_BEGIN_DECLS. There is now a
  replacement macro called COGL_BEGIN_DECLS which is defined in
  cogl-types.h.

• A similar fix has been done for G_GNUC_NULL_TERMINATED and
  G_GNUC_DEPRECATED.

• The CFLAGS were not including $(builddir)/deps/glib which was
  preventing it finding the generated glibconfig.h when building out
  of tree.

54735dec84 Switch use of primitive glib types to c99 equivalents
The coding style has for a long time said to avoid using redundant glib
data types such as gint or gchar etc because we feel that they make the
code look unnecessarily foreign to developers coming from outside of the
Gnome developer community.

Note: When we tried to find the historical rationale for the types we
just found that they were apparently only added for consistent syntax
highlighting which didn't seem that compelling.

Up until now we have been continuing to use some of the platform
specific type such as gint{8,16,32,64} and gsize but this patch switches
us over to using the standard c99 equivalents instead so we can further
ensure that our code looks familiar to the widest range of C developers
who might potentially contribute to Cogl.

So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this
switches all Cogl code to instead use the int{8,16,32,64}_t and
uint{8,16,32,64}_t c99 types instead.

Instead of gsize we now use size_t

For now we are not going to use the c99 _Bool type and instead we have
introduced a new CoglBool type to use instead of gboolean.

426c8b8f41 features: Support more than 32 features!
Currently features are represented as bits in a 32bit mask so we
obviously can't have more than 32 features with that approach. The new
approach is to use the COGL_FLAGS_ macros which lets us handle bitmasks
without a size limit and we change the public api to accept individual
feature enums instead of a mask. This way there is no limit on the
number of features we can add to Cogl.

Instead of using cogl_features_available() there is a new
cogl_has_feature() function and for checking multiple features there is
cogl_has_features() which takes a zero terminated vararg list of
features.

In addition to being able to check for individual features this also
adds a way to query all the features currently available via
cogl_foreach_feature() which will call a callback for each feature.

Since the new functions take an explicit context pointer there is also
no longer any ambiguity over when users can first start to query
features.

07c0b9f89f Add CoglDepthState API
Instead of simply extending the cogl_pipeline_ namespace to add api for
controlling the depth testing state we now break the api out. This adds
a CoglDepthState type that can be stack allocated. The members of the
structure are private but we have the following API to setup the state:

    cogl_depth_state_init
    cogl_depth_state_set_test_enabled
    cogl_depth_state_get_test_enabled
    cogl_depth_state_set_test_function
    cogl_depth_state_get_test_function
    cogl_depth_state_set_writing_enabled
    cogl_depth_state_get_writing_enabled
    cogl_depth_state_set_range
    cogl_depth_state_get_range

This removes the following experimental API which is now superseded:

    cogl_material_set_depth_test_enabled
    cogl_material_get_depth_test_enabled
    cogl_material_set_depth_test_function
    cogl_material_get_depth_test_function
    cogl_material_set_depth_writing_enabled
    cogl_material_get_depth_writing_enabled
    cogl_material_set_depth_range
    cogl_material_get_depth_range

Once a CoglDepthState structure is setup it can be set on a pipeline
using cogl_pipeline_set_depth_state().
