Add CoglDepthState API

Browse Source 
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This removes the following experimental API which is now superseded: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().
