Update the cogl.symbols file
Update the cogl.symbols file

Add and rename the symbols that have been added/renamed during the
development cycle, and also remove those that have been dropped during the
process.

Also continue the quest of purging from the exports lists of the internal
APIs as some of those are no longer referenced by other Cogl components.
