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
Currently when a unique pipeline is created and added to the pipeline
cache that pipeline will live forever which includes keeping a
reference to any large resources that the pipeline has such as
textures. These textures don't actually need to be kept for the
pipeline to be used as a key in the hash table so ideally we wouldn't
do this. This test case tries rendering with a pipeline that has
textures and then checks whether the textures are successfully
destroyed after the pipeline is unreffed. The test is currently marked
as a known failure because the pipeline cache will prevent them from
being destroyed.
