* gdk/win32/gdkwin32.h: Define more message types missing from
mingw headers.

* gdk/win32/gdkevents-win32.c (gdk_event_translate): On WM_DESTROY
call gdk_window_destroy_notify(). It was never called. This
probably meant that the GdkWindow was never freed. Thanks Owen for
noticing (!).

* gdk/win32/gdkwindow-win32.c (gdk_window_internal_destroy): Mark
window as destroyed before calling DestroyWindow(). DestroyWindow()
causes a call to the window procedure (gdk_WindowProc), which
calls gdk_event_translate(), which calls
gdk_window_destroy_notify(), which gets confused unless the window
is set as destroyed.

* gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string): Rename
this function to indicate it's win32 only. Put inside #ifdef
G_ENABLE_DEBUG.

* gdk/win32/gdkevents-win32.c (gdk_win32_message_name): New
debugging function. (gdk_event_translate:) Add a default branch
that uses the above function to print debug messages with all
Windows messages symbolically.

* gdk/win32/gdkprivate-win32.h: Declare it, and
gdk_win32_color_to_string, but only if G_ENABLE_DEBUG.
