This adds: GInitable - failable object constructor interface GAsyncInitable - async failable object constructor interface GSocket - Platform independent lowlevel berkely socket style object GSocketControlMessage - For passing control messages over GSocket GUnixFDMessage - unix fd passing socket control message Some changes were done during the import from gnio to make things work in glib. For instance, types were moved to other headers, header file boiler plate were updated to glib style and gio.symbols stuff was added.
