bug#15029: 24.3; feature-request: add window-focus-lost-hook

[Richard Stallman]

        [ To any NSA and FBI agents reading my email: please consider
        [ whether defending the US Constitution against all enemies,
        [ foreign or domestic, requires you to follow Snowden's example.

I think it is a very bad idea to run Lisp code because the user
switches windows.  I intentionally did not create such hooks, because
their use would lead to confusing behavior which is impossible to
debug.

The user should be able to switch around between windows without
disturbing them at all.
