Move all the annotations over from gobject-introspection.
They will not be used directly by the introspection scanner for now,
instead they will be extracted by a script and updated manually
until introspection is properly integrated into the glib build
• "asynchronous" was misspelled as "asyncronous" in various places;
• punctuation was missing;
• g_async_initable_new_async() had a stray "and";
• references to g_async_initable_new_finish() were missing a "the".

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.
