[cogl] Declare interface types as void and remove cast macros



commit 248a76f5eac7e5ae4fb45208577f9a55360812a7
Author: Robert Bragg <robert linux intel com>
Date:   Wed Oct 9 13:31:12 2013 +0100

    Declare interface types as void and remove cast macros
    
    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.
