    build: Split GOA symbols out into a separate symbols file
    
    On some systems (Mac OS X) it is an error to include symbols in the
    symbols file which are not exported from the library. This can happen if
    building with --disable-goa (or --disable-gnome).
    
    Fix this by generating the symbols file dynamically.

    If this isn't possible, the deprecated function should be split into a static function which contains all 
the code, and the public symbol should
    become a simple wrapper of this static function. This allows the static function to be used inside 
libgdata without causing deprecation warnings.
