Benjamin Otte 41e19757db gdk: Add GDK_DECLARE_EXPORTED_TYPE() ...

This is like G_DECLARE_FINAL_TYPE(), except it doesn't make the class
struct public, so internally all the subclassing in the world can
happen.

Some subtle differences:
- It marks the get_type() function as G_GNUC_CONST
- It doesn't require the parent type
- It uses G_DEFINE_AUTOPTR_CLEANUP_FUNC() instead of the private glib
  chainup method.

Port a bunch of GDK and the whole event controller + gesture machinery
to provew that it works.

As a side effect, we gained a bunch of missing autocleanups.
