removed linux-fb backend files.

	* gdk/linux-fb/*: removed linux-fb backend files.

	* acconfig.h
	* config.h.win32.in
	* docs/README.linux-fb
	* gtk/Makefile.am: remove remaining traces of linux-fb.

	* gtk/gtkwindow-decorate.c: same here. There is some code that
	calls into linux-fb to set window move/resize callbacks. I put it
	in #if 0 as a reminder because we did use decorated windows with
	the DirectFB backend and it did work, so I don't really know why
	this code is needed or how it could work with DirectFB back then.
	The file does actually compile now if DECORATE_WINDOWS is defined,
	but I didn't test with DirectFB to check if it does anything.
