    cogl: Drop CoglHandleObject and CoglHandleClass
    
    They're just typedefs to CoglObject and CoglObjectClass, respectively,
    and the latter is unused already. The former is used in a couple of
    deprecated headers, which can easily be changed.
    
    Change all CoglHandleObject instances to CoglObject, and drop the types
