scanner: Kill glibast

It was a stupid abstraction split, we only support GObject.

* Clean up how we handle c:type - we only set it if we've actually
  seen a corresponding structure.
* Add a warning if we don't see the structure typedef for an
  interface, since that's pretty bogus.  (And fix regress.h to have
  one)
* Rename the "type_name" attribute internally to "gtype_name"
  for clarity.
