* gobject.[hc]:
* gparam.[hc]: provide marshaller specific value_set_*_take_ownership()
variants.
* gvalue.h: shrink GValue's data contents to 2 unions.
* glib-genmarshal.c: fix release and realeas_check hackage by always
using _take_ownership() variants. directly access value contents if
G_ENABLE_DEBUG is not defined.
* gobject.h: add padding pointers to the class struct.
