Neil Roberts 0c8582aad8 cogl: Add an internal utility to maintain a list of callback functions
This adds an internal CoglCallbackList type which is just a GSList of
of function pointers along with a data pointer to form a
closure. There are functions to add and remove items and to invoke the
list of functions. This could be used in a number of places in Cogl.
