Add the composite overlay window to the cache, as this can be a reasonable Xdnd proxy as well.
This is only done when the screen is composited in order to avoid mapping
the COW. We assume that the CM is using the COW (which is true for pretty
much any CM currently in use).

We need to use gdk_threads_add_idle, in order to keep GDK code
under the GDK lock.

(cherry picked from commit 08dd02fe255487f5c7953de9b2c8b63c2e937989)
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names. In GTK2, this header is included by default.

Add an ugly workaround because GTK does not ensure surfaces get flushed
before directly accessing the drawable backed by the surface. This is
not visible on X11 (where flushing is a no-op), but can be seen on
Windows.

The attributes struct has some members that aren't covered by the
attributes_mask so they should always be filled in. The Win32 backend
was using the window type member when creating the window
implementation. Previously this was left uninitialized so it would end
up thinking the window is input_only and nothing would get painted.

TrackMouseEvent is present in user32.dll in all Windows versions we
support. No need to look it up dynamically. No need to fallback to
_TrackMouseEvent from comctrl32.dll.
