These methods are not present in gconf.defs. don't know why. But I think
if callback for gconf is used, these methods need to be binded.

I have the get_car/cdr methods override cause from gconf API doc, the actual
GConfValue's are owned by the pair they are in. Need a FALSE in pyg_new_box().
And get_list still return a Tuple.

BTW,  
override gconf_client_all_entries args
in gconf.override
Py_INCREF the tuple before return it. is it neccessary? if it is, all the
get_list
need to INCREF before return too.
