Try and fix unbind_to when localness of binding has changed
* eval.c (unbind_to): Don't unbind a local binding into the global binding when the local binding disappeared. Inversely, don't unbind a global binding into a newly created local binding. * data.c (set_internal): Make its `buf' arg into a `where' arg so we can specify the frame to use, when applicable. Adjust callers.
